摘要
本文订正1964年由Cridland所作的无髓根属的特征鉴别,详细描述我国发现的第一个无髓根属、种。文中把它同世界上其他地区发现的生根无髓根作了比较,认为它们的区别仅在于次生木质部管胞的大小,故应属同一种。
This paper revises the generic diagnosis of Amyelon, given by Cridland in 1964, and gives a minute description about the first species of Amyelon from China. Although there is a difference in size of secondary tracheids of A. radicans known from other parts of the world, yet they belong to the same species. In this paper, statistical method is used in discription of secondary xylem rays.
