摘 要 ：迄今为止,菱科(Trapaceae)的分类极不统一,知C. D. K. Cook所说,关于种的界限几乎没有一致的意见。苏联学者(例如Vassiljev)对本科植物作了相当细的划分。西欧学者们则倾向于大种,Tutin把13个种合并成1个种。在日本,Nakano通过对中国和日本等东亚国家不同类型的栽培研究,把若干种降级为变种。
Abstract:In this paper a classification of Trapaceae whose specimens were collecte from Hubei province is presented based upon the comparative researches on the results of the cluster analysis, the observations on the potlen morphology under light microscope and the quelitative analysis of habitat. Both morphological discontinuity and ecological isolation were used as the criteria of recognizing species in Trapa. Finally, 17 OTU’s were divided into 5 species and 8 varieties of which 4 were new ones and others were new combinations. The species and varieties are listed below; Trapa incisa Sieb. et Zucc.: T. maximowicii Korsh.; T. bicornis Osb.; T.bicornis Osb. var. quadrispinosa (Roxb.)Z.T. Xiong; T.bicornis Osb. var. bispinosa (Roxb.) Z. T. Xiong; T. bicornis Osb. var. taiwanensis (Nakai) Z. T. Xiong; T. bicornis Osb. var. acornis (Nakano) Z.T.Xiong; T.japonica Fler; T.japonica Fler. var. magicorona Z.T.Xiong; T. japonica Fler. var. longicollum Z.T.Xiong; T.pseudoincisa Nakai; T.pseudoincisa Nakai var. aspinifa Z.T.Xiong; T.pseudoincisa Nakai var. complana Z.T.Xiong.
