BALFouR—NEw SPECIES OF RHODODENDRON. 151 
Rhododendron cruentum, Lévl.* in Fedde Repert. xii (1913), 
284. 
Small tree with thick short branches fully 5 mm. in diameter, 
when a year old clad with dense thick rusty wiry bistrate 
indumentum of long-branched thick-walled fibril-like inter- 
locking hairs with intermixed glands which have multicellar 
stalks, indumentum persistent as a grey-black coating on 
older branches. Foliage-leaf buds unknown. Leaves shortly 
petiolate very thick and leathery, as much as 10 cm. long; 
lamina oval-lanceolate, as much as 7.5 cm. long 3 cm. broad, 
narrowed to the triangularly acute tip which has a short 
red hydathodal mucro, margin recurved, base obtuse or some- 
what wedge-shaped; upper surface dark green somewhat 
glossy with a grooved midrib lined with tomentum especially 
at base, rest of surface smooth glabrous, primary veins about 
8 on each side of midrib hardly visible ; under surface bright 
rusty-red covered all over with a thick bistrate persistent 
indumentum like that of the young stems concealing the leaf 
epidermis completely—the stalked glands intermixed are fewer 
apparently than in Rh. Bureavi; petiole stout, as much as 
2.5cm. long and 4 mm. in diameter, somewhat swollen and ex- 
panded at base, coated with a thick indumentum like that of the 
leaf under-side. Inflorescence of some ro flowers in a true umbel, 
the rhachis shortly woolly and apparently eglandular ; outer 
sterile bracts caudate, the tail ensheathed in a dense cloak of 
rufous indumentum arises from top of and is a little longer 
than a broad ovate or rounded base about 5 cm. long 7 mm. 
broad, this base is glabrous inside rufously hairy and eglandular 
outside, inner fertile bracts more or less persistent during 
flowering oblong spathulate submembranaceous subtruncate 
and apiculate about 1.8 cm. long and 7 mm. broad densely 
clad with adpressed branched rufous hairs, there are no glands ; 
bracteoles about 5 mm. long filiform clavate at top apparently 
not glandular, at the tip coated with adpressed whitish hairs ; 
pedicels medium - stout stiff about 1.4 cm. long completely 
enclosed in a sheath of rusty-red indumentum with which are 
intermixed many red clavate stalked glands. Calyx about 
4 mm. long fulvous cut to near the base into 5 subequal lobes ; 
cup densely lanate with grey hairs mixed with orange-coloured 
clavate stalked glands ; lobes coriaceous not translucent, about 
2.5-3.5 mm. broad, outside clad throughout like the cup, margin
