BALFoUR—NEW SPECIES OF RHODODENDRON. 147 
primary veins, ultimate venation a close network, midrib and 
veins showing more or less detersile floccose hairs sometimes 
glabrous, rest of surface papillate ; petiole about 5 mm. long 
setulose and floccose more or less. Flowers in solitary terminal 
4-flowered umbels; bracts and bracteoles not seen ; pedicels 
about 1.5 cm. long stiff erect reddish-brown clad with fasciate 
seta-like red-brown hairs with a lower stratum of short branched 
floccose hairs, anthopode large. Calyx cup-shaped red about 
I cm. long glabrous outside and inside, slightly fleshy ; cup 
somewhat open about 5 mm. long; lobes subequal irregular in 
shape broadly deltoid or subelliptic or oblong or ovate or rounded 
about 5 mm. long ciliate with short fasciate hairs, often reflexing 
as flower withers. Corolla deep crimson without blotch or spots 
about*3 cm. long tubular-campanulate fleshy glabrous outside 
and inside not gibbous at base 5-lobed; lobes rounded about 
I cm. long a little broader. Stamens 10 unequal shorter than 
corolla, longest about 2.5 cm. long with anther 1.75 mm. 
long, shortest about 1.5 cm. long with anther 1.25 mm. long ; 
filaments slightly widened to base glabrous; anthers brown. 
Disk red lobulate glabrous. Gynaeceum about 3.3 cm. 
long longer than corolla; ovary about 5.5 mm. long ovoid 
truncate grooved densely tomentose with red-brown floccose 
hairs mixed with some stalked red clavate glands ; style 
glabrous stout expanding at top to form a broad disk-plate 
Within the margin of which stand erect 5 dark-coloured lobes 
of the stigma. 
S.E. Tibet. Tsarong. On Ka-gwr-pw, Mekong-Salween 
divide. Lat. 28° 25’ N. Alt. 14,000 ft. On open moorland. 
Shrub of 2-3 ft. Flowers deep crimson. G. Forrest. No. 
14,364. July 1917. Open moorland and on cliffs. Alt. 
14,000-14,500 ft. G. Forrest. No. 14,365. July 1917. 
A distinct species recalling in its habit plants like Rh. brachy- 
anthum and it has also the same kind of calyx. But its corolla, 
stamens and gynaeceum are altogether different, taking one to 
the vicinity of Rh. neriiflorum and I think that 1s probably the 
phylum to which it belongs. The falling tomentum retaining 
its last hold on the veins and midrib recalls forms like KA, 
The same construction is found in Kh. 
Martinianum, Balf. {. et Forrest, a Mekong-Salween species 
of the Souliei series. :
