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.
