Guangdong Province extends across the subtropical and tropical zones.
With favorable climate and plentiful rainfall, this district is extremely rich in plants.
However, the study on the Charophyta in this province is scanty.
The specimens we identified were collected from 4 cities and 10 counties of the
province. The result shows that there are abundant representatives of Chrophyta, espe-
cially in Nitella, in the province.
In this paper, however, only reported are some new taxa of Nitella. The 2 new spe-
cies are Nitella sessilis and N. guangdongensis; the 3 new varieties are Nitella flagellifor-
mis var. conglomerata, N. brevidactyla var. hainanensis and N. pakistanica var. magni-
antheridii; and the 3 new records of distribution in China are Nitella bengalensis Kundu,
N. madagascariensis Zanev. and N. tenuissima var. sanukensis Imah. 相似文献

Yunnan is extends across the subtropical and tropical zones, situated in the sou-
thern border area of southwestern China. This district is extremely rich in plants, and
thus, it has been known as a “Kingdom of Plants”. However, up to the present our
knowledge of the Charophyta in this region has been scanty.
In order to get a thorough understanding of its Charophyta, we identified speci-
mens collected from 13 countries or cities in this province. The result shows that is
especially abundant in Charophyta.
In this paper, however, only are reported new species, new varieties and new re-
cords of China on the Nitelleae. The former two are Nitella hokouensis, N. bicornuta,
N. longicaudata, N. procera, N. brevidactyla, N. papillata, N. pseudohyalina, N. hyalina
var. aberrans and Tolypella yunnanensis; while the third is Nitella globulifera Pal andN. japonica T. F. Allen. 相似文献

青海九种杜鹃的比较解剖和分类位置 总被引:1,自引:0,他引:1
王为义 《中国科学院研究生院学报》1982,20(1):49-58
作者检查了青海九种杜鹃的木材、幼枝和叶子的解剖学性状。 结果表明:
按其生长层上管孔的分布,可以分成半环孔材和散孔材两类;根据木射线的结
构、幼枝和叶表面腺毛的种类,后者又可以分成两类。青海九种杜鹃分别隶于 Sleumer分类系统中两个亚属及两个组和一个亚组。 相似文献

A fossil plant, Yanliaoia sinensis gen. et sp. nov. of late Jurassic is described from
western Liaoning. It is an arborescent conifer, deciduous, with branchlets and leaves
resemble closely those of Sequoia sempervirens.. The form and structure of female
cones and cone scales are similar to those of extinct genus Elatides and living genera
Cunninghamia, Taiwania and Athrotaxis, The female cone, however, is smaller. Cone
scales are spirally arranged, woody, thin and ellipticzl, having a short spine at their
apex. Seeds, globuloidal, without wings, about ten on each scale, and longitudinally
arranged in three to four ranks, which occupy nearly the whole area of the ventral
surface of ovuliferous scales.
The author believes that Yanliaoa and Elatides are two closely allied genera,
evolved roughly in parallel with each other in the late Mesozoic. Yanliaoa may be
one of the ancestors of the living genera of Taxodiaceae. remarkablly the lineal or
sublineal ascendant of Sequoia sempervirens. The so-called “Sequoid jeholensis”(Endos. 1951) may be a branchlet of Yanliaoa sinensis. 相似文献
