| 摘 要： | 本文报道了罗布麻属和白麻属植物叶表面气孔形态的比较观察。结果表明,两者气孔形态的微观性状十分相似,同属一个类型。结合花部形态的比较分析,认为Poacynum Baill。独立成属的依据是不充分、不合理的,应将之归并回罗布麻属Apocynum L 中。列举了原白麻属所隶下2个种的正确学名。

| Abstract: | Observations on the structure of leaf stomata of Apocynum L. and Poacynum Baill. have been made under scanning electron microscope. The fact shows that the characters of the leaf stomata of these two genera are similar. The reason of erecting the Poacynum Baill. as a separate genus is quite insuffi-cent and unreasonable. Together with the floral structure, Poacynum Baill. should be merged into Apocynum L.. |
