BALFOUR—NEW SPECIES OF RHODODENDRON. 143 
lined with black-red vestiges of glands and a few hairs, primary 
veins some 12 on each side very inconspicuous; under surface 
red-cinnamon-brown sometimes. when young pale grey-buff- 
coloured smooth shining with black-red or paler red patches 
here and there specially well seen on the paler-surfaced leaves, 
covered by a complete thin persistent somewhat crustaceous 
pellicle of bistrate indumentum composed of hairs with long 
thick stalks and long vesicular branches spreading horizontally 
and agglutinate as an upper stratum and rosette-hairs on short 
stalks with short vesicular branches as an under stratum, many 
of them are reddened by a secretion which exudes and forms 
crusty black-red blotches large and small over the surface em- 
bedding the hairs, sometimes there is an indication of splitting 
of the pellicle, midrib prominent clad like the rest of the surface, 
rest-of venation concealed by the indumentum, the whole indu- 
mentum penetrated by the mycelium of fungus ; petiole about 
I cm. long stout glabrescent like the stems. Flowers in a ter- 
minal racemose umbel about 15-flowered with a short rhachis 
about 1 cm. long floccose and glandular; flower-bud globose ; 
outer sterile bracts like the outer scale-leaves of vegetative bud 
but with tails; inner bracts persistent during flowering soft 
obovate spathulate rounded at top and shortly mucronulate 
densely silky with white hairs on both sides, towards top out- 
side glabrous, about 2 cm. long 8 mm. broad ; bracteoles shorter 
than pedicels about 7 mm. long thin filiform pilose from base 
and white hair-crested ; pedicels about 2 cm. long floccose and 
sparingly glandular. Calyx minute a fleshy cup with 5 indistinct 
semi-lunate or slightly pointed lobes more or less glandular and 
floccose. Corolla campanulate washed rose deepest on margins 
with small crimson spots posteriorly, about 4 cm. long ; tube 
wide somewhat fleshy at base and there faintly 5-gibbose the 
gibbosities darker coloured, glabrous outside, densely puberulous 
inside ; limb open spreading 5-lobed ; lobes broad about 1 cm. 
long 2.3 cm. broad slightly undulate and crenulate. Stamens 
IO unequal much shorter than corolla and gynaeceum, longest 
about 2.3 cm. long with anther 3 mm. long, shortest about 1.5 
em. long with anther 2 mm. long; filaments widened to base, 
from base upwards through one-half or more of length densely 
villous. Disk glabrous. Gynaeceum about 2.6 cm. long shorter 
than corolla; ovary about 3.5 mm. long cylindric-conoid 
truncate grooved glabrous with surface finely papillate ; style 
stout glabrous clavate below the lobulate discoid stigma. 
W.N.-W.-Yunnan. Mountains north of Atuntzu. Lat. 
28° 35’ N. Alt. 13,000 ft. In open forest. Shrub of to ft. 
Flowers washed rose deepest on margins with crimson markings.
