Pyrgophyllum (Gagnep.) T. L. Wu et Z. Y. Chen is a monotypic genus of Zingibera-
ceae from China. Originally, it was placed in Kaempferia as a subgenus by Gagnepain (1901),
later transferred to Camptandra by Schumann (1904) and to Caulokaempferia by R. M. Smith.
(1972).
In this paper, the authors suggest that the separation of Pyrgophyllum at generic rank is
justified on cytological, morphological and anatomical evidence. It is characterised by the large
lamina-like bracts, which are rarely seen in Zingiberaceae. The margin of each bract is ad-
nate to the main axis of the inflorescence at the base and the lip is lobed. Trichomes unicel-
lular, stomata each with 4-7 lateral subsidiary cells, lateral veins are of three various types of
vascular bundles: girder-shaped, semigirder-shaped and isolated. The pollen grains are spinecent.
The basic chromosome number (x) is 21.
The type species, Pyrgophyllum yunnanensis (Gagnep.) T. L. Wu et Z. Y. Chen (Kaemp-
feria yunnanensis Gagnep.), is only distributed in Yunnan and Sichuan provinces of China.

银缕梅属——中国金缕梅科一新属 总被引:1,自引:0,他引:1
在研究中国稀有濒危植物过程中,通过三年观察,作者发现小叶金缕梅绝无花瓣,无疑应从金缕梅族中分出,其形态特征又明显与无花瓣的蚊母树族和弗特吉族各属有差别,故成立新属——银缕梅属。 相似文献

A new fern genus, Chieniopteris Ching, based upon Woodwardia harlandii Hook.
from South China, is here proposed. Its systematic position seems to be apparently inter-
mediate between Lorinseria Presl of the east North America and Woodwardia Sm. of
the Old World, from the former the genus is distinguished by its upland habitat, by the
uniform fronds of chartaceous or rather subcoriaceous texture with straw-colored stipe
and rachis of the leaves; from the latter by the long creeping rhizome with distant
fronds, by the simple trilobed or generally simply pinnate lamina with a few pairs of
entire or sometimes irregularly lobated lateral pinnae, which are connected at the base
by a narrow wing on each side of the rachis, by the superficial and longer sori and by
the veins anastomosing between the sori and the leaf margin.
While describing the plant as a Woodwardia, Hooker properly noted that it is very
distinct from the oriental Woodwardia japonica (Linn. fil.) Sm. and W. prolifera Hook.
Later Baker transferred Hooker's species under Woodwardia sect. Lorinseria in Synopsis
Filicum in a juxtaposition with Woodwardia areolata (Linn.) Moore, the type of the
genus Lorinseria Presl. It is J. Smith, who referred the southern Chinese plant to Lorin-
seria Presl, with which it is somewhat similar in habit, but differs in characters diagnosed
above, besides a distinct habitat and geographic area.
The new genus is now represented by two species, C. harlandii (Hook.) Ching and
C. kempii (Cop.) Ching, all indigenous in South China, extending southwardly to the
northern part of Vietnam and eastwardly to the islands of southern Japan.
The new genus is named after professor S. S. Chien, director of the Institute of
Botany, Academia Sinica, and president of the Botanical Society of China, to celebratehis 80th. birthday last year. 相似文献
