越南苦苣苔科一新属
A New Genus of Gesneriaceae from Vietnam
摘要
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.关键词
