Abstract

Two new species of Ophiopogon (O. rupestris, O. tristylatus) and one species of Peliosanthes (P. cambodiana) of Asparagaceae (Convallariaceae s. str.) discovered recently in southern Cambodia and in Vietnam are described and illustrated. All described species are probably local endemics with a restricted distribution. Data reported for each described species comprise a standard citation of type specimens, description, list of available paratypes, proposed species epithet etymology, data on ecology, phenology and distribution, as well as short taxonomic remarks.

中文摘要

本文發表三個新物種，分別自越南與柬埔寨南部發現的兩種沿階草（O. rupestris, O. tristylatus），及一種球子草（P. cambodiana）；本文除提供物種的分類描述與圖片外，也提供每個物種所引用的模式標本資訊、副模標本清單、種小名之來源和生態資訊以供辨別。這三個物種很有可能都是特有種且分布範圍狹窄。
