BALFOUR—-NEW SPECIES OF RHODODENDRON. 153 
dense hair tufts with some long-stalked glands; in Rh. cruentum 
the style is glandular and floccose throughout nearly its whole 
length. Then I find that in Rh. cruentum the corolla-tube is 
densely pubescent inside; in RA. Bureavi there are fewer hairs 
but intermixed with them are many clavate glands. On the 
posterior side are many crimson spots which do not appear in 
Rh. cruentum. 
The flowers as a whole of the two species differ in size— 
those of Rh. cruentum being much the smaller. At same time 
I find some variation in flower-size of this species, but the flowers 
never seem to attain the size of those in Rh. Bureavi. 
The finding of Rh. cruentum in N.E. Yunnan gives an 
interesting extension of distribution to the Bureavi type. We 
have Rh. Bureavi from E.N.W. and Rh. cruentum from N.E. 
of Yunnan. The localities, stir eS though they are by the 
breadth of Yunnan, are within the Yangtze basin, and when 
we get to know more of the intervening area one or other of 
them or related forms may be found. Hemsley and Wilson * give 
a record for Rh. Bureavi in Szechwan under Wilson’s number 
3954. The number is not given in Wilson’s list of the plants 
of the Veitchian expedition, and I have not seen the specimen. 
I should not expect Rh. Bureavi to occur in the area of Szechwan 
which Wilson explored; the occurrence of Rh. cruentum would 
conform with experience of other species.
