对中国兰科植物新种云南巾唇兰Pennilabium yunnanense S.C.Chen&Y.B.Luo作了
描述和绘图。该新种与P.acuminatum（Ridley）Holttum较为接近，区别点在于具较小的花朵
，直径仅3cm;花瓣白色且上面有深紫色斑点，以及唇瓣侧裂片顶端有流苏。 相似文献

讨论了北美火烧兰 Epipactis gigantea、卵叶火烧兰 E．royleana和大叶火烧兰 E．mairei之间的异同。过去被许多作者认为是北美火烧兰 E．gigantea和卵叶火烧兰 E．royleana的中国植物实际上应是大叶火烧兰 E.mairei。卵叶火烧兰在中国仅局限于西藏东南部。 相似文献

An attempt has been made in the present paper to discourse on the orgigin and
early differentiation of the Orchidaceae, based on recent information, as well as a
comparative study of some significant characteristics in the most primitive genera ofthis family. Four problems are separately discussed in the following: 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.

There are eleven species of Satyrium hitherto reported in China, among which,
after a detailed examination of herbarium specimens consisting of about 300 plants,
only four forms, represented by S. nepalense D. Don, S. ciliatum Ldl., S. setchuenicum
Kranzl. and S. yunnanense Rolfe, are susceptible of division. S. nepalense is a wides-
pread species with its main distribution centre in indian region, whereas the other
three, with which the present paper deals, are largely distributed in our country.
S. ciliatum is characterized by its pink flowers with spurs about half as long as
the ovary. It is usually found in mountain meadows at an altitude between 1900-
4100m. from Szechuan through Kweichow, Yunnan and Tibet, southwestward to
Sikkim and Bhutan. In all its flowers examined, both female and male organs are
perfect and many have produced capsules. It is, no doubt, the hermaphrodite form as
seen in the ordinary orchids.
S. setchuenicum closely resembles S. ciliatum in habit, distinguished mainly by
having flowers without or with short spurs. These two forms are sympatric. In our
herbarium, for instance, they are sometimes found on a same specimen or the different
sheets with the same field number, such as Y. Tsiang 11454, R. C. Ching 24184, T. P.
Wang 9497, etc. A detailed comparison shows that in S. setchuenicum the anther and
pollinia are abortive or even entirely absent, and the stigma is larger than the
rostellum which usually partly thickens and becomes some-what stigma-like, while in
S. ciliatum the male organ is well developed, and the thin rostellum is larger. Between
these two forms several intermediates are found. It is quite certain that they are dif-
ferent sexual forms belonging to one and the same species, and so called S. setchuenic-
um is but a female form of S. ciliatum.
Another sympatric form is S. yunnanense, characterized by its yellow flowers with
somewhat horizontally extended spurs. Its anther, pollinia and rostellum are very
similar to those of hermaphrodite form of S. ciliatum, but the ovary is narrower and
the stigma is usually smaller. It is interesting to note that in all specimens examined
consisting of 36 individuals, no fruit can be found, while in those of S. ciliatum, includ-
ing both female and hermaphrodite forms, the lower flowers of the racemes are mostly
found to have produced fine seed-capsules. From these facts we may confidently
regard this species as the male form of S. ciliatum.
Thus, we have three separate sexual forms in S. ciliatum, to which eight specific
names previously recorded in China are here referred. Detailed discussion and descrip-
tion as well as a key to the chinese species are given as above. Its geographical distribu-
tion is mapped. The flowers of these three forms are illustrated. All the specimens
cited here, with a few exceptions, are deposited in the herbarium of Institute of Botany,Academia Siaica. 相似文献
