报道了中国秋海棠属等翅组一新种,即赤车叶秋海棠 (Begonia pellionioides YM. Shui & WH. Chen)。此新种特产于云南东南部的石灰岩山生境,与海南秋海棠 (Begonia hainanensis Chun & F. Chun) 相似,但不同在于其叶片较长,叶基楔形,叶尖渐尖至尾尖,花被片背面具刺毛,蒴果具上边缘平截的三角形翅。此外,补充描述了秋海棠属等翅组拟长柄秋海棠 (Begonia sublongipes YM. Shui)的花部特征。

 Begonia pellionioides YM. Shui & WH. Chen, a new species of the genus Begonia L. (sect. Petermannia (Klotzsch) A. DC., Begoniaceae), is described and illustrated. The new species is endemic to limestone areas in Southeastern Yunnan Province, China, and is most similar to Begonia hainanensis Chun & F. Chun but distinguished by its more elongated leaves with cuneate base and acuminate to caudate apex, tepals adaxially with spiny hairs and sharply triangular capsulewings with truncate superior margin. Besides, the unknown flower morphology of previously published Begonia sublongipes YM. Shui in Begonia sect. Petermannia is described.
