IIo BALFOUR—NEW SPECIES OF RHODODENDRON. 
Alt. 13,000 ft. On ledges of cliffs. Shrub of 2 ft. G. Forrest. 
No. 14,293. July 1917. 
This is a delightful species of the Forrestii series a speci- 
men of which with flower has come to Mr. J. illiams, 
Caerhays Castle, in a postal packet, one of the first-fruits of 
Forrest’s exploration during the year 1918. It is the same as 
Forrest’s No. 14,293 of his 1917 collection which is evidently 
the duplicate in foliage to which he refers on the ticket of 
16,695. Its conspicuous features are :—the elongated oblan- 
ceolate to oblong leaves showing purple-red under surface with 
thin bistrate indumentum of long branched hairs and smaller 
rosette-hairs without any glands, more or less detersile ; densely 
floccose eglandular pedicels, calyx, and ovary; large corolla ; 
puberulous disk. I look upon the red under surface of the 
leaves of this species as indicating the persistence of a juvenile 
character now fixed as a specific character of the adult, an 
explanation which is also put forward in the case of Rh. Forrestii 
(see p. IIQ).
