Although Guangxi represents one of the distribution centres of begonias in China, the sect. Diploclinium (Wright) A. DC is not well documented herein. In this article, we illustrate a new species belonging to this section, Y.N.Huang, X.X. Feng & R.K.Li, which has been discovered in southern Guangxi. mostly resembles in elliptic leaf blade, palmate veins, dichasial cyme, three styles, axile placentation, and unequally 3-winged capsule. On the other hand, is characterized by creeping rhizome, pilose stipule, red and densely pilose petiole, pubescent leaf blade and pilose inflorescence bract, sparsely pilose ovary and the zygomorphic androecium, differing from the erect stem at anthesis, the green and densely villous petiole, the glabrous stipule, leaf blade, inflorescence bract, ovary and actinomorphic androecium in . Considering its small population size and narrow distribution, its conservation status is categorized as 'Endangered (D)' according to the IUCN Red List Categories and Criteria.
虽然广西是中国秋海棠属植物的分布中心之一，但本文对二室组（Wright）A. DC的记载并不详尽。在本文中，我们描述了一个属于该组的新物种，黄玉娜、冯雪雪和李荣喜，它是在广西南部发现的。该新物种在椭圆形叶片、掌状叶脉、二歧聚伞花序、三枚花柱、中轴胎座以及具不等的三翅的蒴果方面与该组的其他物种大多相似。另一方面，该新物种的特征在于其具匍匐根状茎、具柔毛的托叶、红色且密被柔毛的叶柄、具柔毛的叶片和具柔毛的花序苞片、子房疏被柔毛以及左右对称的雄蕊群，与花期直立的茎、绿色且密被长柔毛的叶柄、无毛的托叶、叶片、花序苞片、子房以及辐射对称的雄蕊群的[某物种]不同。鉴于其种群规模小且分布范围狭窄，根据世界自然保护联盟（IUCN）红色名录类别和标准，其保护状况被列为“濒危（D）”。
