An investigation of a questionable species of the genus Alseodaphne led to the discovery of a new genus Alseodaphnopsis H. W. Li & J. Li, gen. nov., separated from Alseodaphne Nees, and a new species Alseodaphnopsis ximengensis H. W. Li & J. Li, sp. nov., endemic to Yunnan province, China. This new species is characterized by having big, axillary, paniculate inflorescences, as well as large, subglobose fruits. Based on DNA sequence data from two gene regions (nuclear ribosomal ITS and LEAFY intron II), we investigate its phylogenetic position within the Persea group. Phylogenies using maximum parsimony (MP) and Bayesian inference (BI) support the recognition of Alseodaphnopsis as a distinct genus but do not resolve well its relationship within the Persea group. The new genus is circumscribed, eight new combinations for its species are made, and a description and illustration of the new species are provided.
对可疑的杨桐属（Alseodaphne）物种的调查导致了一个新属——阿尔西达福尼斯属（Alseodaphnopsis）H. W. Li & J. Li，gen. nov. 的发现，该属与 Alseodaphne Nees 属分离，并发现了一个新种——阿尔西达福尼斯滇西亚种（Alseodaphnopsis ximengensis H. W. Li & J. Li，sp. nov.），该种为中国云南省特有种。这个新种的特征是具有大的腋生、聚伞状花序，以及大的近球形果实。基于来自两个基因区域（核核糖体 ITS 和 LEAFY 内含子 II）的 DNA 序列数据，我们研究了它在柿属（Persea）内的系统发育位置。基于最大简约法（MP）和贝叶斯推断（BI）的系统发育支持将阿尔西达福尼斯属（Alseodaphnopsis）作为一个独特的属，但不能很好地解决其在柿属（Persea）内的关系。该新属被定义，对其 8 个种进行了新组合，并提供了该新种的描述和插图。
