144 BALFOUR—NEW SPECIES OF RHODODENDRON. 
or less deciduous stratum and becoming brown, midrib elevated 
less hairy and paler in colour; petiole bright green slightly 
winged grooved above as much as 2 cm. long always more or 
less clad with floccose hairs. Flowers 12-15 in a compact 
terminal umbel ; bracts persistent at first flower-opening, outer 
sterile thick crustaceously leathery chestnut-brown rounded- 
ovate mucronate keeled inside densely glandular and puberulous 
towards the top floccose, the glands capitate orange-coloured 
short-stalked, outside furfuraceously puberulous at top and 
over mucro red- or white-floccose; intermediate are mem- 
branous and broadly ovate-oblong; inner fertile bracts long 
spathulate nearly 4 cm. long and 1 cm. broad more or less 
membranous, outside and inside densely covered with white 
curled adpressed hairs, mucronate at the apex and there hair- 
crested with red or white hairs; bracteoles filiform slightly 
clavate at tip hairy from the base about 1.2 cm. long shorter 
than pedicels; pedicels about 2 cm. long eglandular densely 
floccose-pubescent. Calyx small about 1.5 mm. long fleshy cut 
to near base into 5 rounded lobes which are glabrous on the 
back and have a few marginal cilia. Corolla pale rose with a 
posterior basal crimson blotch and a few crimson spots above it, 
openly campanulate from the base about 3.5 cm. long slightly 
oblique, outside glabrous, inside at base puberulous, 5-lobed ; 
lobes short and broad about 1.2 cm. long and 2.2 cm. broad 
emarginate and undulate. Stamens ro unequal shorter than 
corolla and gynaeceum, longest about 2.4 cm. long with anthers 
about 3 mm. long, shortest about 1.3 cm. long with anthers 
2.5 mm. long; filaments stoutish dilated downwards and from 
the base densely puberulous to above the ovary. Disk appa- 
rently glabrous. Gynaeceum about 2.8 cm. long shorter than 
corolla; ovary about 5 mm. long cylindric truncate grooved 
completely covered by an indumentum of floccose somewhat 
fasciate reddish and uncoloured ascending adpressed hairs, 
eglandular ; style glabrous pale-coloured slightly expanding

W.N.W. Yunnan. Mekong-Salween divide. In pine forests. 
Alt. 11,000-12,000 ft. Lat. 28° 20’ N. Flowers pale rose with 
a blotch of crimson at base. G. Forrest. No. 14,060. June 
IQI7. 
One of these N.W. Yunnan Rhododendrons, with bistrate in- 
dumentum on the under-leaf surface, which occupy a position in 
the genus somewhere between the Lacteum series and the Roxie- 
anum series. It sheds its upper stratum of indumentum leaving 
the under stratum as a whitish layer. The prominent red 
blotch at the base of the corolla is a distinguishing mark of the 
species amongst its allies.
