These are plants with chartaceous more or less broadly 

 lanceolate leaves, usually dark coloured above, borne upon 

 fairly stout twigs, and they are always floccose or floccose 

 and glandular in parts. The development of wax in Rh. 

 ceraceuin and Rh. lukiangense tends to exclude other forms 

 of indumentum. The many red flowers on the short 

 stout rhachis of inflorescence form a large compact truss. 

 Whilst 5-lobed corollas and 10 stamens are constant {Rh. 

 ceraceum, Rh. lukiangense), we find 5-6 lobes and 10-12 

 stamens in Rh. antJiosphaerurti and 7 lobes with 14 stamens 

 in Rh. hylothreptum. This set is found only from the 

 Likiang range northwards to Tseku and the Chungtien 

 plateau. ' 



KEY TO THE SPECIES. 



Leaves chartaceous not rigid, more or less broadly lanceo- 

 late or oblanceolate, base obtuse, mat above, 

 sometimes glossy beneath. 



Corolla red 5-7-lobed, glabrous outside, glabrous or 

 puberulous inside. Stamens 10-14. Style

 or spots. 

 Ovary puberulous. Pedicel under 1 cm. puberu- 

 lous.
