146 BALFOUR—NEW SPECIES OF RHODODENDRON. 
rubro-glandulosus staminibus longior corolla brevior ; stigma 
discoideum lobulatum. 
Species ex affinitate Rh. Sheltonae, Hemsl. et Wils. sed altior, 
foliis juvenilibus supra sparsim et floccosim pilosis, adultis ex 
toto glabris, pedicellis floribusque majoribus, corolla maculata 
divergens. 
E.N.W. Yunnan. Lichiang Range. Alt. 10,000-11,000 ft. 
Lat. 27° 30’ N. Open situations in pine forests. Shrub 9-25 
ft. Flowers pale rose. G.-Forrest. No. 10,075. June 1913. 
E.N.W. Yunnan. Lichiang Range. Alt. 11,000—12,000 ft. 
Lat. 27° 30’ N. In pine and mixed forest. Shrub 6-18 ft. 
Flowers rose-pink.. G. Forrest. No. 10,114B. June 1913. 
A larger plant than Rh. Sheltonae, Hemsl. et Wils. in 
all its parts. Apart from size it differs in the complete 
glabrousness of the older leaves. The young leaves have on 
their upper surface as they open from the bud a few scattered 
hair tufts which soon disappear leaving no trace ; on the under 
surface there are no hairs or glands. Consequently, the older 
leaves -have both surfaces entirely bare of appendages. In Kh. 
Sheltonae the under surface always shows red or yellow glands 
as minute points all over the surface. The lobes at the base of 
the leaf are not so rounded here as they are in Rh. Sheltonae. 
Then the corolla is always red-spotted in Rh. rhantum—hence 
its name. The species is one of a difficult complex, which will 
require much examination of living plants before its legitimate 
microforms can be accurately diagnosed. We have seedlings 
of Rh. rhantum (No. 10,075) raised from Forrest’s seed, presented 
by Mr. J. C. Williams, Caerhays Castle, and we may look to 
having flowers of the species in a few years.
