212 BALFOUR—NEW SPECIES OF RHODODENDRON. 
situations on the margins of pine forests. G. Forrest. No. 
12,713. July 1914. 
Rh. adenogynum, Diels was the species first described of an 
aggregate of forms characterised by a thick buff-coloured or 
rufous uniform mat tomentum on the under side of the leaves, 
by a calyx with relatively large lobes—about 1 cm. long— 
and by an ovary and style bearing clavate glands. It may 
be taken as the central form. Rh. adenophorum, here described 
as a member of the aggregate, is distinguished by the viscidity 
of its buds, by the admixture of clavate red glands with 
tomentum on the young shoots and leaf petioles, by the long 
glands scattered over the upper leaf-surface, by the long-stalked 
glands upon the flower pedicels.
