Taxonomic notes on genus Trapa L. (Trapaceae) in China
摘要
Abstract
The genus Trapa L. (Trapaceae) is a kind of aquatic and polymorphic plants. Based on literature survey, field work, specimen examination and cultivation observations, taxonomic significance of major morphological characters was evaluated. The sizes of fruit bodies and crowns are found to be the reliable diagnostic characters for circumscription of the species, while the sizes of fruit beaks and numbers of horns for identification of the varieties. Consequently, two species, Trapa incisa and T. natans, with the six varieties of T. natans, are recognized with descriptions. The names of the four varieties of T. natans are newly combined with exception of var. bispinosa, viz. T. natans var. quadricaudata, var. complana, var. magnicorona and var. komarovii. The names of ten species and twelve varieties are newly reduced to synonyms. Lectotypes are designated for T. amurensis, T. bispinosa, T. dimorphocarpa, T. japonica and T. manchurica.关键词
