本文综述了与Disporum和Prosartes属的区别问题有关的形态学和细胞核学资料。叶绿体基因编码rbcL的两个物种的每个Disporum和Prosartes加上一个每个悬雍垂属，Streptopus和Tricyrtis进行测序。这些数据清楚地区分了两个属Prosartes（N. America）和Disporum（E.亚洲），传统上合并在后者的名称。Disporum和Prosartes之间的分歧比它们的每一对组成物种之间的分歧要大得多，并且比Disporum和Uvularia之间或Prosartes和Streptopus之间的分歧要大得多。因此，rbcL序列数据支持恢复属Prosartes。对Prosartes的同义词进行了概述，并提出了一个新的组合。
A review of the morphological and karyological data relevant to the problem of the generic distinctness of Disporum and Prosartes is presented. The chloroplast gene encoding rbcL for two species of each Disporum and Prosartes plus one of each Uvularia, Streptopus and Tricyrtis was sequenced. The data clearly separate two genera Prosartes (N. America) and Disporum (E. Asia) that were traditionally combined under the latter name. There is much more divergence between Disporum and Prosartes than between each pair of their component species, and considerably more than between Disporum and Uvularia or between Prosartes and Streptopus. The rbcL sequence data thus support the restoration of the genus Prosartes. A synonymic conspectus of Prosartes is given, and one new combination is proposed.
