I00 BALFOUR—NEW SPECIES OF RHODODENDRON. 
interlocking and becoming matted as a compact smooth 
slightly scintillating surface, its under layer of rosette-hairs 
with short spreading vesicular unicellular branches (inter- 
mediate hair-forms also occur), midrib elevated, rest of venation 
hidden; petiole about xr cm. long stout grooved above 
coated with an indumentum like that of young stem, more or 
less glabrescent. Flowers in terminal few-flowered (5—6) umbels ; 
bracts unknown ; bracteoles about g mm. long slightly shorter 
than pedicels linear-clavate brown membranous pilose with 
white hairs throughout on the back; pedicels about 1.2 cm. 
long clad with stalked ovoid red glands and floccose greasy 
often red or brown branched hairs. Calyx small about 2 mm. 
long cut to the base into 5 lobes cup outside glandular and 
hair-coated like the pedicels; lobes oblong or rounded or 
semi-lunate about 1.5 mm. long sparingly glandular and floccose 
on back, margin ciliate and glandular, the glands red-stalked. 
Corolla dull soft rose without blotch but with faint crimson 
spots fleshy about 3 cm. long openly campanulate from base, 
slightly oblique 5-gibbous, puberulous inside, glabrous outside, 
5-lobed, posterior lobe the largest semi-lunate about 1.3 cm. 
long 2 cm. broad emarginate crenulate. Stamens 10 unequal 
very short, longest about 1.7 cm., shortest about I cm. long, 
the anthers grouped in the centre of the flower over the style ; 
filaments yellow stout broadly widened downwards, from base 
upwards through one-third to three-fourths of length puberulous 
with many short stout pointed hairs and glandular with short- 
stalked ovoid uncoloured glands; anthers oblong ovoid about 
3 mm. long in long stamens, 2 mm. in short. Disk slightly 
puberulous below ridges of ovary. Gynaeceum very short 
about 7 mm. long shorter than shortest stamens; ovary ovoid 
with truncate top about 2.5 mm. long slightly grooved glandu- 
lar with long-stalked ovoid ascending glands, also coated with 
floccose branched greasy hairs often brown or red ; style very 
short not twice length of ovary slightly decurved glabrous 
hardly expanding under the small-lobed and lipped stigma. 
SE. Tibet. Tsarong. Open situations on rocky slopes of 
Ka-gwr-pw, Mekong-Salween divide. Lat. 28° a5 Ni Alt. 
12,000 ft. Shrub of 4 ft. Flowers dull soft rose with faint 
crimson markings. G. Forrest. No, 14,242. July 1917. 
A species recalling by its habit members of the Sanguineum 
series, and also plants like Rh. perulatum, Balf. f. et Forrest. 
Its leaves, while of the general form found in the cycles of 
affinity named, are not so aggregated at the ends of the annual 
growths, and in consequence the branches do not show the 
nodular swellings which such leaf-disposition commonly brings 
_ about. The scale-leaves of the foliage-bud do not persist
