香槐属分类学研究随记

Taxonomic Notes on Cladrastis Raf. (Leguminosae)

摘要:

基于对标本和文献的比较研究,确认豆科香槐属(Cladrastis Raf.)中小叶香槐(C. parvifolia C. Y. Ma)、藤香槐(C. scandens C. Y. Ma)、秦氏香槐(C. chingii Duley & Vincent)与本属分布最广的翅荚香槐[C. platycarpa (Maxim.) Makino]为同种植物。其中,小叶香槐被处理为翅荚香槐的一变种,即C. platycarpa var. parvifolia (C. Y. Ma) Z. Q. Song, D. X. Xu & S. J. Li,藤香槐与秦氏香槐被处理为翅荚香槐原变种的两个新异名。同时讨论了翅荚香槐的分类地位及其散布。

Abstract:

Examinations of literatures and specimens in herbaria have shown that three Chinese species of the genus Cladrastis Raf. (Leguminosae), viz. C. parvifolia C. Y. Ma, C. scandens C. Y. Ma and C. chingii Duley & Vincent, are conspecific with C. platycarpa (Maxim.) Makino, a species distributed widely in China and Japan. C. parvifolia is here treated as a variety, namely C. platycarpa var. parvifolia (C. Y. Ma) Z. Q. Song, D. X. Xu & S. J. Li, comb. et stat. nov., while C. scandens and C. chingii are reduced to new synonyms of C. platycarpa. Finally, The taxonomic position and the geographic dispersal of the speices were discussed.
