136 BALFOUR—NEW SPECIES OF RHODODENDRON. 
or less with the persistent outer scale-leaves of the foliage-buds 
showing very short annual growths producing about 5 foliage 
leaves at the top. Outer scale-leaves of foliage-bud ovate acute 
or shortly acuminate keeled somewhat crustaceous puberulous 
outside, sericeous at the top inside, margin fringed with branched 
brownish hairs more numerous at the tip; inner scale-leaves 
yellowish more membranous ligulate-spathulate with adpressed 
hairs inside and outside, hair-fringed. Leaves petiolate as much 
as 5.5 cm. long often less; lamina thickly leathery oval or 
oblong-oval as much as 5 cm. long 2.5 cm. broad often less, obtuse 
and ending in a prominent tuberculate dark red mucro, margin 
cartilaginous slightly revolute, base obtuse and prolonged down- 
wards as a narrow wing on each side of the petiole ; upper surface 
olive-green mat, the midrib primary veins (some 10 on each side) 
and ultimate venation grooved making a finely areolate or some- 
what shagreened surface, which is apparently glabrous but 
marked by vestiges of fallen glands and branched brownish hairs 
the groove of the midrib lined with hairs particularly at the base ; 
beneath with a paler green epidermal surface veiled by a thin 
layer of floccose much-branched hairs most abundant on the 
veins but not confined to them, many small red glands accom- 
pany the hairs, midrib prominently raised and floccose and 
glandular, the veins and ultimate venation reddened and con- 
spicuous but not raised, the indumentum sometimes falling off ; 
petiole about 5 mm. long grooved above glabrescent but with 
some floccose brown hairs or their vestiges. Flowers in a 
2-flowered terminal umbel ; outer bracts unknown : inner bracts 
persistent during flowering, yellowish tinted red forming a group 
around the pedicels, largest about 2 cm. long nearly 1 cm. broad 
broadly spathulate rounded at top and slightly mucronulate, at 
the top inside and outside (more sparingly) sericeous with white 
hairs, ciliate; bracteoles unknown - pedicels unequal as much 
as 1.3 cm. long strict erect glabrous. Calyx small fleshy 
saucer-shaped about 1.5 mm. long with 5 rounded lobes often 
yellow quite glabrous outside faintly ciliate. Corolla tubular 
campanulate about 3 cm. long deep rose-coloured unspotted 
slightly 5-gibbous, glabrous inside and outside, 5-lobed ; lobes 
rounded emarginate 1 cm. long 1.5 cm. broad. Stamens 10
