报道了采自广州从化的野牡丹科肉穗草属（Sarcopyramis）和兰科独蒜兰属（Pleione）各一种新分布植物，分别为楮头红（S. nepalensis Wall.）和独蒜兰[P. bulbocodioides (Franch.) Rolfe]，凭证标本存放于华南农业大学植物标本馆(CANT)。两种植物在从化的分布地海拔260～300 m，是二者在中国大陆的最南部、海拔最低的分布记录，对研究两属植物的扩散机制、垂直分布及气候变化对物种迁移的影响等理论问题具有参考意义。
Two new recorded plants, S. nepalensis Wall. and P. bulbocodioides (Franch.) Rolfe, respectively belonging to Sarcopyramis of Melastomatceae and Pleione of Orchidaceae, were reported in Guangzhou City, Guangdong Province. The voucher specimens were deposited in the Herbarium of Forestry College, South China Agricultural University (CANT). The two species were found at high 260～300 m altitude in Conghua, which was the southernmost and the lowest altitude records for them so far. The new records would provide important references for the effects of diffusion mechanism, vertical distribution, climate change on species migration, and some other theoretical problems.
