摘要：

作者检查了青海九种杜鹃的木材、幼枝和叶子的解剖学性状。结果表明：

按其生长层上管孔的分布，可以分成半环孔材和散孔材两类；根据木射线的结

构、幼枝和叶表面腺毛的种类，后者又可以分成两类。青海九种杜鹃分别隶于

Sleumer分类系统中两个亚属及两个组和一个亚组。

Abstract:

Anatomical characteristics of the wood, the branchlets and the leaf blades of nine

representative species of Rhododendron on Qinghai plateau have been examined in order

to explore their taxonomic position.

On the basis of vessel figures in growth rings, the wood of Rhododendron can be

divided into two divisions, namely, semi-ring pore and scattered pore wood. Because of

the differences of the wood ray-structure and the glandular hairs on the branchlets and

the leaf blades, the latter can be further classified into two subdivisions.
