摘要:

广义的斜蒴苣苔属(Loxocarpus R. Br. sensu lato)为马来西亚植物区系和巽他古陆的特有类群,其生态习性、营养器官和蒴果形态高度相似,但花部器官却显示出一定的分化和多样性。分子系统学证据显示,该属实际上是一个多系群。根据形态性状特异性组合,结合分子系统学证据,该文将广义的斜蒴苣苔属拆分为3个属,包括狭义的斜蒴苣苔属(Loxocarpus sensu stricto)及姚氏苣苔属(Yaoa)和斜钟花属(Paraloxocarpus)2新属。该文提供了3个属的检索表和描述,对相关的21种做出新组合。

Abstract:

The genus Loxocarpus R. Br. sensu lato is the endemic group of Southeast Asia and Sundaland. The species in Loxocarpus exhibit differentiation and diversity in floral organs with similar habits and morphology in vegetative organs and fruits. However, evidence from molecular phylogenies indicates that Loxocarpus sensu lato is polyphyletic. According to correlated morphological characters combined with molecular data, we separated Loxocarpus sensu lato into three genera, including Loxocarpus sensu stricto and two new genera, i.e. Yaoa and Paraloxocarpus. In the present study, the three genera were described with a key to them, and 21 new combinations were proposed.

Key words: Southeast Asia, new genera, new combinations, Loxocarpus, Yaoa, Paraloxocarpus, Gesneriaceae
