154 BALFOUR—NEW SPECIES OF RHODODENDRON. 
most leaves, never terminal; outer bracts leathery rounded 
mucronulate, lepidote and puberulous outside, finely shortly 
ciliate on margin; inner bracts more oblong; bracteoles un- 
known ; pedicels about 6-8 mm. long clad with setae short hairs 
and peltate scales. Calyx minute about .5 mm. long forming a 
fleshy ring with an indication on margin of 5 lobes, densely 
hairy and lepidote outside the margin of the lobes more or less 
setulose. Corolla small about 8 mm. long with a short funnel- 
shaped tube puberulous inside expanding into a 5-lobed limb ; 
lobes oblong-oval lepidote outside longer than the tube. Stamens 
Io unequal the longest a little longer than the corolla, shortest 
about 5 mm. long; filaments filiform with a tuft of hairs above 
the glabrous base. Gynaeceum longer than corolla and stamens. 
Young fruit green narrowly oblong-ovoid puberulous and lepi- 
dote; style glabrous. Capsule oblong straight about 6 mm. 
long 2.5 mm. in diameter finely pilose and lepidote.

The date of collection of specimens of this species has not been 
favourable. The flowers are all gone, only a few withered ones 
remaining on the young fruit. The fruits are not mature. The 
leaf-buds are hardly formed. Notwithstanding these deficiencies 
the species is so distinct I am able to describe it, although im- 
perfectly. It belongs to the phylum of Rh. mollicomum, Balf. 
f. et W. W. Sm., and Rh. hemitrichotum, Balf. f. et Forrest. The 
latter species with its white wax-covered underleaf without hairs 
(save on midrib) and buds cobwebbed with hairs is easily 
diagnosed. The former is a nearer ally but without the bristle- 
shaped hairs of Rh. pubescens, has buds with long cilia, and much 
larger flowers. They all belong to the Scabrifolium series, but 
none of them have the asperities near the margin of the leaf on 
its upper side that are so prominent in Rh. scabies and other 
members of the series.
