40 BALFOUR—NEW SPECIES OF RHODODENDRON. 
often glued more or less together and to the base of the stem 
the indumentum of which as the stem elongates adheres to the 
glandular scale-leaves and is removed, the scale-leaves seem 
to fall off quite early sometimes. Leaves petiolate as much 
as 15.5 cm. or more long; lamina oblanceolate as much as 
13.5 cm. long 5 cm. broad, acuminately narrowed at the apex 
into a blunt beak ending in an inconspicuous hydathode, 
margin entire quite flat hardly cartilaginous, narrowed from 
the upper third downwards to the cuneate base which is 
prolonged as a narrow wing along the upper edges of the 
petiole; upper surface opaque dark olive-green with a 
grooved red-tinted midrib and about 16-20 primary veins on 
each side also grooved, the surface lightly shagreened and 
glabrous but showing traces of juvenile hairs; under surface 
pale grey-green or pale cinnamon-coloured coated with a thin 
unistrate scintillating indumentum easily rubbed off of short- 
stalked few-armed (3 to 6) rosette-hairs, the arms short broad 
unicellular vesicular uncoloured or brown, the surface owing to 
the fall of the indumentum frequently becomes naked and in 
old leaves of a somewhat pale olive-green, midrib raised straw- 
coloured free of indumentum but punctulate with bases of fallen 
hairs, primary veins showing beneath the indumentum ; petiole 
about 2 cm. long stout winged with narrow laminar wing on each 
side above, green or purpling, glabrescent but showing remains 
of juvenile flock-hairs. Flowers in a compact terminal umbel 
of some 10-12 flowers enclosed during flowering by the sticky 
bracts ; outer bracts crustaceous with somewhat membranous 
margin, dark-brown rounded or broadly ovate coated on back 
with red sessile tuberculate glands, inner fertile bracts more 
membranous elongated as much as 3 cm. long and 8 mm. broad 
at top spathulate with a strap-shaped straw-coloured stalk and 
shorter elliptic or oval somewhat greenish blade densely pilose 
with sticky hairs apiculate, the apiculus hair-crested ; bracteoles 
very short about 8 mm. long filiform pointed pilose throughout ; 
pedicels about 2 cm. long strict red puberulous with a few flocks 
of reddish hairs. Calyx small saucer-shaped fleshy, margin 
showing 5 rounded or pointed lobes, the whole glabrous save 
for a few obscure marginal hairs to the lobes. Corolla openly 
campanulate from the base, whitish or flushed rose or pale rose 
with a crimson basal blotch, about 4 cm. long glabrous outside, 
puberulous inside, base slightly fleshy and 5-gibbous, 5-lobed ; 
lobes broad about 1.5 cm. long and 2.2 cm. broad emarginate 
somewhat undulate. Stamens 10 unequal shorter than corolla, 
longest about 2.8 cm. long with dark-purple oblong anther about 
3.25 mm. long, shortest about 1.5 cm. long with ovoid anther 
about 2.25 mm. long; filaments pale-coloured considerably
