98 BALFOUR—NEW SPECIES OF RHODODENDRON. 
back gland-fringed, glands stalked. Corolla pale rose openly 
campanulate 3.5 cm. long glabrous out and in 5-lobed ; lobes 
about 1.5 cm. long and 2 cm. broad rounded imbricate emar- 
ginate. Stamens ro unequal, longest about 3.2 cm. long a 
little shorter than corolla with anthers oblong about 3 mm. long, 
shortest about 1.7 cm. with anthers about 2 mm. long nearly 
globose ; filaments widened below, from the base upwards to 
above ovary puberulous. Disk minutely puberulous below 
ovary. Gynaeceum about 3.4 cm. long, slightly shorter than 
corolla exceeding stamens ; ovary 2.5 mm. long conoid narrowed 
into base of style grooved densely. glandular, glands clavate 
orange-coloured and stalked; style glandular at very base with 
shortly stalked glands hardly expanding into lobulate lipped 
stigma. Capsule somewhat sickle-shaped about 2.5 cm. long 
and 6 mm. in diameter pale brown or tinted glaucous pink 
slightly warted dehiscing from apex by 5 valves. Seeds very 
pale straw-coloured flattened oblong about 3 mm. long and 
0.5-I mm. broad ; body of seed striate about 1.5 mm. long with 
arillar wing of nearly equal width all round and a chalazal crest 
and funicular broad extension.

Lat. 28° 12’ N. Open thickets and scrub. Shrub of 4-6 ft. 
Flowers pale rose. G. Forrest. No. 13,949. June 1917. 
A most distinct and beautiful species first found by 
Forrest during his exploration of Yunnan in 1914, in fruit, 
and with a single withered flower on a ripening capsule. He 
has obtained specimens in flower in course of the exploration 
in which he is now engaged, and these enable me to complete 
the description of the species. From seeds collected in 1914 
Mr. J. C. Williams of Caerhays Castle has raised seedling plants. 
The species belongs pethaps to the Souliei series or should 
be placed between the Souliei and Selense with some other 
species with partially glandular style, and is readily distin- 
guished by its habit and the nodulose swellings of the branches 
at the end of each year’s growth, by the very thick rigid small 
leaves disposed in false whorls which persist for three years, 
markedly punctulate with persistent glands on the underside, and 
by the 2~3-flowered umbels of long-stalked flowers. The nodulose 
swellings on the stem are of the same character as those which 
are found on Rh. temenium, Balf. f. et Forrest, a beautiful species 
from the Tsarong, and in plants of the Sanguineum series— 
all showing the same habit of leaves in pseudo-whorls. The
