常山属的初步研究

Dichroa Lour., a small genus of Saxifragaceae, contains about 12 species, ranging from the mainland of S. E. Asia southward to Pacific islands. But most of the species are more restricted in distribution. Of the 12  recognized species,  six  are known from South China and Indochina; three are confined to west and northwest New Guinea; two are endemic to the Phillipines. Only one species is widely distributed in S. E. Asia.  In the present paper, the genus is divided into two sections  and two series based on the number of stamens and the characteristics of the ovary.  One spe- cies is described as new.

中国姜科一新属——苞叶姜属

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.
