Members of the genus are widely distributed and frequently found in plant materials. In an effort to investigate the species diversity within this genus, leaf samples collected from Guizhou and Hainan provinces in China were examined. This study led to the discovery of two previously undescribed taxa. Phenotypic examination, combined with phylogenetic analysis based on concatenated ITS and LSU D1/D2 sequences, confirmed their affiliation with and supported their designation as novel species. One of the new species, , is phylogenetically closely related to , whereas represents a distinct lineage, clearly separated from other known species. Detailed descriptions, illustrations, and comparative discussions with their nearest relatives are provided. These findings contribute two additional species to the genus and enhance our understanding of diversity in China.
该属的成员分布广泛，常在植物材料中发现。为了调查该属内的物种多样性，对从中国贵州和海南省采集的叶片样本进行了检查。这项研究发现了两个以前未描述过的分类群。通过表型检查，结合基于ITS和LSU D1/D2串联序列的系统发育分析，证实了它们与该属的归属关系，并支持将它们指定为新物种。其中一个新物种， ，在系统发育上与 密切相关，而 代表一个独特的谱系，与其他已知的 物种明显分开。提供了详细的描述、插图以及与它们最近亲缘种的比较讨论。这些发现为该属增加了两个新物种，并增进了我们对中国 多样性的理解。
