The “Quan Fang Bei Zu”, a first dictionary for Chinese plants, which contains 27
volumes in its first collection and 31 volumes in its second collection, was completed by
Chen Jing-yi in 1253, the First Year of Bao You of Li Zong in Song Dynasty. The
first part of this encyclopaedia of plants is devoted to flowers. The second part is of
more varied nature, dealing with fruit trees, plants in general, herbs, trees, agriculture
and sericulture, vegetables, and medicinal herbs. These two collections cover 267 kinds
of plants, each of which is described under two categories separately: The first category,
“Si Shi Zu” in Chinese, meaning “facts of the plants” concerned, which again divided
into 3 entries, i.e. the history, miscellaneous information and sundry bits of the plants.
The second category, “Fu Yong Zu” in Chinese, meaning poetry, which divided into
10 meters, wherein the plants are described and eulogized in poetrical expressions.
Later on, the “Quan Fang Bei Zu” was used as a blueprint for some famous books
in China, for example, the “Qun Fang Pu” and the “Guang Qun Fang Pu” all written
and compiled after its model. It is known today that in China there are only two
extant hand writting copies of it, one in Beijing Library, the other in the Library of
Yunnan University. Both of them are listed as the best national books. Outside China,
it is known that a third copy of is in the Congress Library in U.S.A. As for the ori-
ginal wood-carving copy printed during the period of the Song Dynasty, it is known so
far that one copy is kept in the Library of Culture Ministry of Japan. The Beijing
Agriculture Publishing House has made a decision to photograph this carved copy in
the Culture Ministry of Japan as one of the “Precious Series of China Agriculture
Science”. The book plays a very important role in the study of chinese botany, agri-culture science, medicine, history and literature. 相似文献

The “Iconographia Plantarum” written by Wu Chi-Tseng in the Qing Dynasty
(A. D. 1848) is a classical monumental work in the literature of botany. 1714 species
of plants widely-spread all over 19 provinces of our country, especeally in Jiangxi,
Hunan and Yunnan Provinces, were described in this book.
nan and Yunnan Provinces, were described try, especeally in Jiangxi, Hunan and Yun.
In order to make the plant names coincide with the original material as possible,
the author had commented upon chinese herbal in considerable detail. Most of the
plants were illustrated after their habitual appearence in somewhat clear manner.
As a means for identifying certain species of the plant, this work has been playing an
important role in development of modern botanical science in China.
In modern taxonomical books a great deal of chinese name of plants are originated
from this book, and they were available for reference to numerous researchers both at
home and abroad. On account of inadequate observation, a lot of mistakes or misleadings
occured in this book, and often been overlooked by the later botanists. Some of the
modern authors still adhere to the work “Iconographia Plantarum”and even quoting
the erroneous statement from it, thus we have to correct.
This paper annotates and commentates the misleading items of 36 species of plant,
and calls for the attention to the future readers.

It is generally accepted that tea plant (Thea sinensis L.) is originated in China,
where has numerous varieties, According to the literature, the selected work of tea
plants may be traced as early as to the 3rd-5th century A.D. The number of varie-
ties discovered in recent years reached more than 300. Besides, a large number of
wild species were discovered. In all tea varieties, the crown canopy, leaf size and
the date of sprouting were different. It was proposed that according to the crown
canopy, leaf size and the date of sprouting. The principle of the classification of
Chinese tea varieties may be 3 orders. The first order named “group”, it contains
macrophanerophyte group, microphanerophyte group, and frutex group. The second
order named “type”, it contains extreme large leaf size, large leaf size, medium leaf
size and small leaf size. The third order named “species”, it contains the early-
sprouting species, medium-sprouting species and late-sprouting species.

The present paper deals with the following three aspects:
1. It attempts to discuss the problems on primitive forms of the family Araliaceae.
The genus Tupidanthus Hook. f. & Thoms. was considered by H. Harms (1894) and H.
L. Li (1942) as primitive, whilst another genus Plerandra A. Gray was regarded as
primitive by R. H. Eyde & C. C. Tseng in 1971. Having made a detailed comparison of
the taxonomical characters of these two genera, the present authors believe that both
genera are not the most primitive in the Araliaceae. Their affinit yis not close enough
and they possibly evolved in parallel lines from a common ancestor which is so far un-
known yet.
2. By studying the systems of the past, the present authors believe that none of them is entirely satisfactory. Bentham (1867) recognized five ‘series’ (in fact, equival-
ent to ‘tribe’ with the ending-eae of names) based on the petaline arrangement in the
bud, the numbers of stamen and the types of endospem. This is a plausible funda-
mental treatment for the Araliaceae, but choosing the endosperm as a criteria in dividing
tribe is artifical. As we know today, both ruminate and uniform endosperm are usually
presente in the same genus. Seemann’s system (1868) divided the Hederaceae (excl.
Trib. Aralieae) into five tribes, in addition to the locules of ovary. The criteria are
essentially the same as Bentham’s. The system of Hams (1894) divided the family into
three tribes. Two tribes, Aralieae and Mackinlayeae, of Bentham are retained, but
other groups were combined in the Trib. Schefflereae. However, Harms did not retain
one of those three oldest legitimate names which had named by Bentham, that is con-
trary to the law of priority in the International Code of Botanical Nomenelature. Hut-
chinson (1967) adopted seven tribes for the family. The criteria essentially follow those
of Bentham, but the inflorescence is overstressed. The inflorescence is an artifical taxono-
mical character in dividing tribes, because of some dioecious plants, such as Meryta sin-
clairii (Hook. f.) Seem., have two types of inflorescence in male and female plants. Ac-
cording to Hutchinson’s arrangement, the male and female plants would be put in se-
parate tribes.
3. The present authors are of the opinion that in the study of a natural classi-
fication of plant groups emphasis should be laid not only on the characters of the repro-
ductive organs, but on those of vegetative organs as well. The present revised system is
based principally upon the characters of both flowers and leaves of the five tribes as
follows:
Trib. 1. Plerandreae Benth. emend. Hoo & Tseng
Trib. 2. Tetraplasandreae Hoo & Tseng
Trib. 3. Mackinlayeae Benth.
Trib. 4. Aralieae Benth.
Trib. 5. Panaceae Benth. emend. Hoo & Tseng 相似文献

Cypripedium subtropicum S. C. Chen et K. Y. Lang is a phytogeography-
cally significant new species with its habit, inflorescence and column very similar to
those of Selenipedilum of tropical America. It is found in Mêdog of southeastern Xi-
zang, China. Its slender leafy stem bears at the summit a many-flowered raceme, am-
ounting to 1.5 m in height. Although its ovary is unilocular—this is the reason why
we place it in Cypripedium, the column characters resemble those of Selenipedilum. For
example, the staminode is rather small and its long stalk is very similar in texture and
color to the filament of the fertile stamens. Obviously, it is a primitive new species re-
lated to Selenipedilum based on the similarities mentioned above.
In the subfamily Cypripedioideae, as generally recognized, Selenipedilum is the
most primitive genus, from which or whose allies Cypripedium is derived. Of phyto-
geographical significance is the fact that Selenipedilum occurs in Central America and
northern South America, while a cypripedium akin to it is discontinuously distributed
in subtropical Asia. This suggests that Selenipedilum or Selenipedilum-like form be
once continually distributed in North America and eastern Asia when the climate there
was warmer, as it is in the subtropics today. The floristic relationship between Central
America and subtropical Asia appears to be closer than expected, as shown by the dis-
tribution patterns of Tropidia, Erythrodes, etc. Based on the occurrence of all six sec-
tions and particularly the most primitive form in eastern Asia, Cypripedium seems to
be of Asian, rather than Central American, origin. Selenipedilum possesses some very
primitive characters, such as trilocular ovary, vanilla-scented fruit, seed with sclerotic
testa, simple column and more or less suffrutescent habit. The latter is considered by
Dahlgren & Clifford (1982) to be one of ancestral characters of monocotyledons, which
is now very rare not only in Orchidaceae but also in all monocotyledons. It is indeed
necessary to make further investigations on Selenipedilum and also the new species pub-lished here, as well as a detailed comparison between them. 相似文献

Acanthochlamydoideae, a new subfamily of Amaryllidaceae, is proposed in the pre-
sent paper, based upon the monotypic genus Acanthochlamys which was detected by
the writer in 1979 and named Didymocolpus as a new genus but was preceded by P. C.
Kao in 1980 under the former name. The genus is indeed of great morphological in-
terest. It has semicylindric leaves with a deep furrow on the ventral and dorsal sides
respectively. The lower part of the leaf is connate with, or adnate to, the lower mid-
rib of a rather large and membranous vagina . Such a feature, as far as we know, is
very rare in the monocotyledons.
The flower resembles that of Amaryllidaceae in having inferior ovary, six stamens
and corolla-like perianth with a rather long tube. But it is quite different in other
characters, such as head-like cyme, leaf-like bracts and bisulcate leaves, which all are
foreign to any taxon known in the Amaryllidaceae. On the other hand, it bears some
resemblance particularly in habit and inflorescence to Campynemanthe of the Hy-
poxidaceae, and also to Borya and Bartlingia of the Liliaceae (in the tribe John-
sonieae), but differs in its long perianth-tube and curious leaf structure. It is highly
probable that the resemblance between them is only superficial and not indicative of
direct or close relationship.
This is no doubt a very curious plant of which we still know incompletely, and
for which an appropriate place in the monocotyledons has not yet been found. Con-
sidering its floral characters, however, it seems safe for the present to place it as a
separate subfamily in the Amaryllidaceae and is juxtaposed with the Ixiolirioideae
and Amaryllidoideae, the only two subfamilies of Amaryllidaceae according to H. Mel-
chior (1964), and, of course, to either of them it is not directly related. Its true affinity
remains problematic.
The only species, Acanthochlamys bracteata, is found in Mar-er-kan (102°12'N,
31°47'E), Qian-ning (101°30'N, 30°33'E), Xiang-cheng (99°39'N, 28°54'E) and Dau
cheng (100°10'N, 29°03'E) in western Sichuan of southwest China, in open bushland
or grassland at an altitude between 2700—3500 meters. Its geographical distribution is
mapped and its morphological details are illustrated to facilitate its identification.

The morphological characters in the genus Orobanche were evaluated from the
taxonomic point of view. The author finds that the plants of this genus are relatively similar
to each other in respect to characters of vegetative organs, fruits and seeds. But the differences
in the floral structures can be served as a basis for delimitating infrageneric taxa. The seed
coat of 18 species and pollen grains of 6 species were also examined under scanning electron
microscope (SEM). They seem to have little significance for distinguishing species.
The result supports G. Beck’s (1930) division of the genus Orobanche into 4 sections, of
which 2 occur in China, based on the characters of the inflorescence, bracteoles and calyx.
The author considers that some characters, such as anther hairy or not, upper lip of corolla
entire or not, lower lip longer or shorter than the upper one, the state of corolla-tube inflec-
tion and the hair type of filaments and plants, are important in distinguishing Chinese species.
A key to the species of Orobanche in China is given.
This genus consists of about 100 species, and is mostly confined to Eurasia, with over 60
species found in Caucasus and Middle Asia of USSR, where may be the mordern distribu-
tional centre.
Orobanche L. in China is represented by 23 species, 3 varieties and l forma. As shown in
Table 1, most species (12 species) are found in Xinjiang, which clearly shows a close floristic
relationship between this region and Middle Asia of USSR. 6 species are endemic to China,
of which 4 are confined to the Hengduan Mountains (Yangtze-Mekong-Salwin divide).
The relationships between this genus and related ones of Orobanchaceae are also discussed.
The author holds the following opinions: the genus Phelypaea Desf. should be considered as a
member of Orobanche L. Sect. Gymnocaulis G. Beck, the monotypic genus, Necranthus A.
Gilli endemic to Turkey, is allied with Orobanche L. Sect. Orobanche, the monotypic genus,
Platypholis Maxim, endemic to Bonin Is. of Japan, is far from Orobanche L. in relation and
should be regarded as a separate genus.
The 11 OTU’s, including all the sections of Orobanche L. and 7 genera of Orobanchaceae,
and 15 morphological characters were used in the numerical taxonomic treatment to test the
above-mentioned suggestions. After standardization of characters, the correlation matrices were
computerized. The correlation matrices were made to test the various clustering methods. At
last the UPGMA clustering method was chosen and its result is shown in a phenogram. The
result of numerical analysis is basically in accordance with the suggestions. 相似文献

1) The Compositae in Tibet so far known comprise 508 species and 88 genera,
which nearly amounts to one fourth of the total number of genera and one third of the
total number of species of Compositae in all China, if the number of 2290 species and 220
genera have respectively been counted in all China. In Tibet there are all tribes of Com-
positae known in China, and surprisingly, the large tribes in Tibetan Compositae are
also large ones in all China and the small tribes in Tibet are also small ones in all China.
Generally speaking, the large genera in Tibet are also large ones in all China and the
small genera in Tibet are likewise small ones in all China. In this sense it is reasonable to
say that the Compositae flora of Tibet is an epitome of the Compositae flora of all China.
In the Compositae flora of Tibet, there are only 5 large genera each containing 30
species or more. They are Aster, Artemisia, Senecio, Saussurea and Cremanthodium. And
5 genera each containing 10—29 species. They are Erigeron, Anaphalis, Leontopodium,
Ajania, Ligularia and Taraxacum. In addition, there are 77 small genera, namely 87%
of the total of Compositae genera in Tibet, each comprising 1—9 species, such as Aja-niopsis, Cavea and Vernonia, etc.
2) The constituents of Compositae flora in Tibet is very closely related to those of
Sichuan-Yunnan provinces with 59 genera and 250 species in common. Such a situation
is evidently brought about by the geographycal proximity in which the Hengtuang Shan
Range links southeastern and eastern Tibet with northern and northwestern Sichuan-
Ynnnan. With India the Tibetan Compositae have 59 genera and 132 species in common,
also showing close floristic relationships between the two regions. Apparently the floris-
tic exchange of Compositae between Tibet and India is realized by way of the mountain
range of the Himalayas. The mountain range of the Himalayas, including the parallel
ranges, plays a important role as a bridge hereby some members of the Compositae of
western or northern Central Asia and of the northern Africa or of western Asia have
migrated eastwards or southeastwards as far as the southern part of Fibet and northern
part of India, or hereby some Compositae plants of eastern and southeastern Asia or
Asia Media have migrated northwestwards as the northern part of Central Asia.
Some of the species and genera in common to both Tibet and Sinjiang indicate that
this weak floristical relationship between these regions is principally realized through two
migration routes: one migration route is by way of the Himalayas including the parallel
ranges to Pamir Plataeu and Tien Shan, or vice versa. The other migration route is by
way of northern Sinjiang to Mongolia, eastern Inner Mongolia, southwards to Gansu,
Qinghai (or western Sichuan), eastern Tibet up to the Himalayas, or vice versa.
However, Tibet is not entirely situated at a migration crossroad of the floral ele-
ments. An ample amount of the data shows that Compositae flora have a particular
capability of development in Tibet. of the total number of species of Tibetan Com-
positae, 102 species and 1 genus (Ajaniopsis Shih) are endemic. Besides, 8 genera are re-
gional endemics with their range extending to its neighbourhood. The higher percentage
of endemics at specific level than at generic in Tibetan Compositae may be a result of
active speciation in response to the new enviromental conditions created by the uplifting
of the Himalayas. The flora in Tibetan Plateau as a whole appears to be of a younger
age.
3) The uprising of the Himalayas and of the Tibetan Plateau accompanied by the
ultraviolet ray radiation, the microthermal climate and the high wind pressure has, no
doubt, played a profound influence upon the speciation of the native elements of Tibetan
Compositae. The recent speciation is the main trend in the development of the Com-positae flora native in Tibet in the wake of upheaval of the plateau. 相似文献

The present paper is devoted to a study of the basic morphological and anatomical
characteristics of the endemic family Rhoipteleaceae from China. The fundamental
pattern of the morphological and anatomical characteristics of the Rhoipteleaceae is
similar to those of the Juglandaceae in wood anatomy, resinous peltate scales, apetaly,
bicarpellate pistils, one-seeded fruits and exalbuminous seeds. Whereas Rhoipteleaceae
has stipules; perfect flowers with superior 2-loculed ovaries, anatropous ovules and two
integuments; vessel elements of the secondary xylem with the scalariform perforation,
and 2–8 (18) pores on the oblique plate being observable; vascular rays heterocellular
and tricolporate pollen. The above characteristics–at least most of them, agree
pretty well with those depicted by Manning in his “Pre-Juglandaceae”. It is quite
possible that the Juglandaceae is derived from “Pre-Juglandaceae”by way of the
Rhoipteleaceae, as the morphological and anatomical features as indicated above tend to
show that the Rhoipteleaceae is more primitive than Juglandaceae.
The Rhoipteleaceae was previously considered as related to the Betulaceae or
Ulmaceae, a view, which the present study does not prove to be acceptable. Both Takh-
tajan (1969) and Cronquist (1968) pointed out that the Juglandales, Urticales, Myrica-
les, Fagales are all direct derivatives from the Hamamelidales. However, since the
Rhoipteleaceae is simillar to the Betulaceae in wood anatomy and pollen, it seems that
there too could have certain relationships between the Rhoipteleaceae and the Betula-ceae in the course of evolution. 相似文献

The Chinese medicine “Chuipencao” is studied. But, as a matter of fact, this
Chinese name represents two distinct forms, one with broad leaves and the other with
narrow leaves. As a result of a comprehensive study on gross morphology, pollen mor-
phology, histological structure, isozymes, GC analysis of chemical constituents of the
plants in question has shown that the narrow-leafed form is different from the broad-
leafed form and therefore is considered as a new species, Sedum angustifolium Z. B.Hu et X. L. Huang sp. nov. 相似文献

三种数值方法在几种六道木分类中的应用 总被引:1,自引:0,他引:1
In the last 10—20 years there has bee n increasing awareness of the problem con-
cerning the aims and practices of taxonomy. In particular, there has been growing
interest in the development of numerical methods in biological taxonomy as an aid to
making systematics a quantitative science, a step which comes in time to almost every
scientific discipline.
Numerical taxonomy is the evaluation by numerical methods of the affinity or
similarity between taxonomic units and the employment of these affinities in erecting
a hierarchic order of taxa. The present rapid development of these ideas is presuma-
bly a result of the development of computer techniques.
Numerical taxonomic approach has been applied to the studies of entomology and
microbiology in China to some extent since 1975. But so far it hasn’t been commonly
used in botany. The present report is a preliminary study on 9 spp. of the genus
Abelia. A set of binary data with 54 characters is used for computing association
coefficient; and a set of quantitative data with 47 characters for distance coefficient
and correlation coefficient. For the mathematical models were chosen the non-metric
simple matching association coefficient, the geometrical distance of Riemannian space
and correlation coefficient. Computational procedures are stepwise presented in detail
and computer programmes are written in the background of Algol-60 language. Cluster analysis is compared with simple linkage, average linkage and multi-correlation.
The results of DC and CC for 9 spp. of Abelia agree closely with the traditional
taxonomy, because the data we collected mainly come from morphological characters.
It would seem that the results of quantita tive data are more appropriate for seed
plants. It is, therefore, postulated that our programes are complementary and very
useful to a wide range of classification entities, such as microbes, animals and plants
in present situation in China.
In conclusion, a comparison between the conventional taxonomy and numerical
taxonomy has been made, and a brief discussion of three problems, i.e. the monothetic
versus polythetic, divisive versus agglomerative, weighting versus unweighting.

The fern genus Diplaziopsis C. Chr. of Index Filicum has long been considered as
a monotypic one, with the sole species, D. javanica (B1.) C. Chr. from tropical Asia. In
1906, H. Christ described a second species, Allantodia cavaleriana Christ (=D. cavale-
riana C. Chr.) from Kweichow, West China, but this was since not fully recognized by
fern students in general, being often considered as a variety of the first species. This
is certainly a mistake, as is shown by ample herbarium specimens today. In the recent
work on the genus, the writer has found among the herbarium material two additional
new species from China, thus bringing the genus up to four species in Asia, mainly from
China, where, as it is, the genus has its center of development from the long past.
Phylogenetically, Diplaziopsis C. Chr. represents one of the offshoots from the great
stock of diplazioid ferns, of which the genus Diplazium Sw. constitutes the main body
of the group and from which our genus differs chiefly in its leaves of a thin texture with
reticulated venation, but not so much in its type of indusium as it has generally been
emphasized by most botanists in the past, for, as it is, the type of indusium in Di-
plaziopsis also prevails in many species of Diplazium, for which C. B. Clarke (Trans.
Linn. Soc. ser. 2, Bot. I:495, 1880) created, but really superfluously, a subgenus Pseudal-
lantodia, about which the writer will dwell in another paper in the near future. Suffice
it to say here that the indusium in Diplaziopsis as revealed by the species treated here
is, indeed, typical of diplazioid ferns, only often, as it happens, with its adaxial edge
pressed so tight under the expanding sorus that it is unable to open freely along its upper
free edge and, as a result, its thin vaulted back bursts open from the pressure of the ex-
panding sorus underneath.
As a result of the present study, following four species of the genus have been re-
cognized.
Diplaziopsis javanica (B1.) C. Chr. Ind. Fil. (1905) 227.
Wide spread in tropical Asia, northwardly to Bakbo and the southern part of Yun-
nan, China.

In conclusion, it may be pointed out that with the modern plant taxonomy pursued
in a more efficient manner than in the past, and especially by the introduction of the
cytotaxonomic methods, the so-called “monotypic genera”, as conceived by the orthodox
systematists, will continue to prove, to a great extent, to be lack of enough scientific
ground. The fact that the “monotypic genus” of Diplaziopsis C. Chr. is now found to
be a genus of four well-defined species is once again an instance to illustrate the pointat issue. 相似文献

While we were investigating the world Veroniceae we found the genus Wulfenia Jacq.
discontinuously distributing. W. carinthiaca and W. baldaccii are found in south-eastern Europe
and W. orientalis in Turkey and Lebanon, whereas W. amherstiana is a native of W. Hima-
laya. Such a pattern of distribution, discontinuous between the Mediterranean and W. Himala-
ya, as far as we know, is hardly frequent. After comparing carefully the specimens from these
two places and examining their pollen grains we got the impression that the difference between
the plants occuring near the Mediterranean and those in Himalaya is so big that they should
no longer be placed in the same genus. It would be necessary, therefore, to describe W. amhe-
rstiana as a new and separate genus (we name it Wulfeniopsis Hong). Its corolla is not 2-
lipped, but with four lobes (not five) lanceolate, acuminate and erect (not spreading). The
stigma is very small, not 2-lobed. Pollen grains are much smaller, with colpi more narrow and
lacking of membranes, and their exines are smooth (not reticulate). It’s chromosome numberis 2n = 16 (not 18). 相似文献

The Baiyandian Lake lies at 115°56′ E. and 38°55′ N. It is about 8 m above
sea level, with an area about 312 square km. There are abundant aquatic plants here, inc-
luding flowering plants of 30 families, 46 genera, 66 species and 3 varieties besides one in-
troduced species. 32 species are erect ones covering about 48.5% of the total number of species
in this lake, 20 are submerged ones, about 30.3%, 9 are leaf-floating ones, about 13.6% and 5
are floating ones, 7.6%. The soil at the bed of the lake is very fertile and the depth is appro-
priate, favouring various plants. The coverage is large, sometimes it may reach 100%, for
example, in communities of Phragmites communis, Hydrilla verticillata, Hydrocharis dubis,
Trapa bicornis, etc. Although the Baiyandian Lake is located in the temperate zone, the floristic
elements are complex. There are tropic-subtropic elements and elements of high-frigid zone
as well. When compared respectively with the floras of the Lakes Jingbo Lake, Honghu Lake
and Lugu Lake, the flora of this lake is found more similar to that of subtropic Honghu Lake
than to those of the other lakes, which shows that it hase a character transitional between the
south and the north in China. Further studies of the floristic relationships are needed in order
to exploit and use the resources of the aquatic plants in this lake. 相似文献

The present paper deals mainly with the karyotype analysis of five
materials in Angelica dahurica collected in Yanbian of Jilin, Anguo of Hebei, Yuxian of
Henan, Hangzhou of Zhejiang and Suining of Sichuan. They are under the names
“Dongbeidahuo”, “Qibaizhi”, “Yubaizhi”, ”Hangbaizhi” and “Chuanbaizhi” respe-
ctively. Among then “Dongbeidahuo” is a wild plant, which occurs in northeastern
China, and the others are cultivated as important crude drugs in some provinces. “Qi-
Baizhi” and “Yubaizhi” have been identified as conspecific with the wild Baizhi-“Do-
Ngbeidahuo” (A. dahurica) according to the external morphological features, whereas the
other cultivated ones, “Hangbaizhi” and “Chuanbaizhi”, treated as a variety (A. dahu-
rica var. formosana).
The results of karyotype analysis are shown in Plate 1, 2, with the formula 2n=22
=12 m+2 mSAT+4sm+4st. The karyotypes described here are constantly characterized by
satellites attached to the fourth pair of metacentric chromosomes and differ from the pu-
blished reports on the other species of the genus. It is reasonable to say that the five
materials collectively named “Baizhi” are taxonomically closely related to each other
and could be regarded as conspecific. Since the second chromosome pair is submetacen-
tric in “Dongbeidahuo”, it may be justifiable to separate the wild plant from the cul-
tivated ones and treat them as two separate varieties. 相似文献

Genus Atractylodes (Fam. Compositae) is the main source of two important
Chinese traditional drugs, “Baizhu”and “Cangzhu”, both being long used as a
stomachic.
After a general survey and taxonomical study, it has been found that “Baizhu”
was only derived from A. macrocephala Koidz. (A. ovata auct. Fl. Orient. Asiat. non
A. P. DC.), while “Cangzhu” were mainly from A. lancea (Thunb.) DC. and A. lancea
DC. var. chinensis Kitam.
Comparison of the components in the rhizomes of Chinese Atractylodes has been
made by TLC and GLC. The results have shown to be in accordance with their mor-
phological features and pharmaceutical merits.
“Baizhu”, A. macrocephala, with its leave pinnately incised, is characterized by the
presence of rich atractylon and absence or lack of atractylodin. As for “Cangzhu”, A.
lancea and A. lancea var. chinensis with their leave not incised or only lobed, are cha-
racterized by high contents of atractylodin, β-eudesmol and hinesol, but poor in atrac-
tylon.
The above conclusion may be of value to both the classification and utilization of
this group of Chinese medicinal plants.
