摘要:

本研究发现,100年前描述的石蝴蝶属(Petrocosmea)物种昆岛石蝴蝶(Petrocosmea condorensis Pellegr.)并非该属植物,而是代表一个独立的新属。该物种花冠扁面状,叶片近圆形,花丝线形,蒴果圆锥状卵球形,2瓣裂;形态学性状十分独特。分子系统发育分析表明,该种位于苦苣苔科(Gesneriaceae)苦苣苔亚科(Didymocarpoideae)芒毛苣苔族(Trichosporeae)的斜蒴苣苔亚族(Loxocarpinae),并与该亚族中其他若干属组成的分支呈姐妹群关系,系统位置特殊。基于分子系统发育与形态学证据,本研究将该种提升为新属——振宇苣苔属(Zhenyuenes),并对其作出新组合处理。

Abstract:

The findings of this study reveal that a species(Petrocosmea condorensis Pellegr.), described in Petrocosmea one hundred years ago, in fact represents an independent genus in Gesneriaceae. This species is characterized by a flat-faced corolla, suborbicular leaf blades, linear filaments, and conical-ovoid capsules dehiscing into two valves, exhibiting a series of unique morphological characters. Molecular phylogenetic analyses demonstrated that this species belonged to the subtribe Loxocarpinae(Tribe Trichosporeae) within the subfamily Didymocarpoideae of Gesneriaceae and is sister to a clade comprising several other genera. Based on morphological and molecular phylogenetic evidence, we here elevated this species to a new genus, Zhenyuenes, with the establishment of a new combination.

Key words: Vietnam, new genus, new combination, Zhenyuenes, Gesneriaceae
