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

报道日本虎舌兰Epipogium japonicum Makino在中国四川西部的新记录，并讨论了该种与虎舌兰E. roseum (D. Don) Lindl.的形态差异。过去将日本虎舌兰处理为虎舌兰的异名是不恰当的。日本虎舌兰间断分布于日本和中国的四川西部高海拔地区及台湾。 相似文献

讨论了长距美冠兰Eulophia dabia及其近缘种的分类与命名问题。Eulophia dabia的基名Bletia Dabia乃是D．Don(1825)合法发表的最早名称，尽管D．Don的“Dabia”很可能是在袭用Hamilton的“dubia”时拼写上的笔误。为了避免进一步的混乱，明智的做法是接受Don拼写的加词，而避开其语源上的麻烦。在分类方面，可以接受Hooker(1890)将Eulophia campestris Lindl．、E．rupestris Lindl、E．ramentacea Lindl．与Bletia Dabia D．Don：予以合并的观点，以及Deva&Naithani(1986)将Eulophia hormusjii Duthie并入 E．dabia的做法。此外，本文还将Eulophia turkestanica (Litw．)Schltr．和E. faberi Rolfe也归并入 Eulophiadabia。因此，长距美冠兰是一个广布种，白土库曼东部经塔吉克、阿富汗东部、巴基斯坦、克什米尔地区，印度北部、尼泊尔、锡金、不丹、缅甸北部直到中国(云南西南部、四川中部到东部、贵州西南部和江苏)，海拔在400~2300 m之间。 相似文献

Apostasioideae, a small subfamily of Orchidaceae, is largely distributed in tropical
Asia with its northern limit extending to the Ryukyu Islands and south China. The first Chinese
species of this subfamily was reported by E. D. Merrill (1927) based on a specimen collected
from Hainan (McClure 9519, AMES), which he regarded as Apostasia wallichii R. Br. As
later labelled by E. F. de Vogel, it is in fact identical with A. odorata Bl., a widespread spe-
cies also found in southern Guangdong, Guangxi and Yunnan of China. It was not until re-
cently that the true A. wallichii was collected from southwestern Yunnan bordering on Burma,
which is initially reported here. In addition, an interesting new species, A. ramifera S. C. Chen
et K. Y. Lang, is described from Hainan.
The only Chinese species of Neuwiedia has long been known as N. veratrifolia Bl. (of.
Iconographia Cormophytorum Sinicorum 5: 602, t. 8034. 1976, and Flora Hainanica 4 180, t.
1078. 1977), which, however, was considered by de Vogel (1969) to be not found in China. In
de Vogel's revision, no Chinese taxon but a variety, N. zollingeri Rchb. f. var. singapureana
(Baker) de Vogel, is cited with some doubt based on a specimen of Hainan (F. C. How 73122,
in young fruit, AMES). N. zollingeri var. singapureana is in fact quite different from N.
veratrifolia by having glandular hair, much shorter inflorescence and flattened filaments. As
recently pointed out by de Vogel and G. Barretto (in Journ. Taiwan Museum 37: 78. 1984),
the plants found in Hongkong, as well as those in Guangdong and Yunnan, possess glandular
hair and short inflorescence. They are identical with the Vietnamese species N. balansae Gagnep.,
which was reduced by de Vogel to a synonym of N. zollingeri var singapureana. E. F. de
Vogel's suggestion seems to be acceptable except the varietal rank. It is treated here as a se-
parate species, N. singapureana (Baker) Rolfe, according to its fruit and hair characters. Thus
we have altogether one species of Neuwiedia and three species of Apostasia in China, including a new species and a newly recorded one. 相似文献

弥散山蚂蝗Desmodium diffusum(新拟)不同于大叶拿身草D. laxiflorum,然而前者在中国却不被承认。弥散山蚂蝗广布于中国,与大叶拿身草相较更为普遍,而大叶拿身草仅分布于中国的广东、广西、台湾及云南南部。崔现举等将弥散山蚂蝗置于单序山蚂蝗D. unibotryosum种中。根据国际命名法规,单序山蚂蝗为一非法名称,属弥散山蚂蝗的异名。本文介绍了弥散山蚂蝗和大叶拿身草的分类历史、种的检索表、种的文献、异名及分布。同时,指定了弥散山蚂蝗的后选模式。 相似文献
