中国粟米草科分类修订

Taxonomic Revision of Chinese Molluginaceae

摘要:

粟米草科（Molluginaceae）隶属于石竹目，是一个分类极为困难的被子植物类群，关于该科的分类学界定在众多不同被子植物分类系统中争议颇大。在最近的分子系统学研究中，粟米草科的范围被准确界定，全球共包含11属。在此基础上对中国粟米草科类群进行了分类修订，最终确认中国产粟米草科植物5属7种，其中线叶漆姑粟草[Hypertelis umbellata（Forssk. ）Thulin]为中国分布新记录种。更新了分种检索表，并提供了各属形态描述及相关物种的地理分布图。

Abstract:

Molluginaceae is a taxonomically difficult family in Caryophyllales, and its circumscription was much controversial among different systems of angiosperm classification. Based on result from a recent molecular phylogenetic study, the circumscription of Molluginaceae was well-established and 11 genera within the family were accepted, and thus a taxonomic revision of Molluginaceae in China is revised accordingly. Finally, seven species belong to five genera of Molluginaceae were accepted, and the species Hypertelis umbellata (Forssk.) Thulin is newly recorded from China. Detailed morphological description of all genera and distribution maps of all species accepted, as well a key to all of relevant species, were provided.
