50 BALFOUR—NEW SPECIES OF RHODODENDRON. 
spots, about 4.8 cm. long, glabrous outside, puberulous at the 
base inside, not gibbous, 5-lobed ; lobes short and broad about 
8 mm. long and 3 mm. broad emarginate crenulate. Stamens Io 
unequal, shorter than corolla, longest about 3.3 cm. long with 
anther oblong 4 mm. long, shortest about 2 cm. with anther 
3 mm. long; filaments expanding to the base and from there 
through about one-third finely puberulous. Disk puberulous 
below ovary. Gynaeceum about 3.8 cm. long shorter than 
corolla longer than stamens; ovary about 6 mm. long dark- 
brown when dry, conoid truncate slightly grooved densely 
glandular, glands shortly-stalked ; style glandular through three- 
fourths of length glabrous in upper fourth, hardly expanding 
below a broad discoid lobulate lipped stigma. 
E. N. -W. - Yunnan. Sungkwei divide. Eastern flank. Alt. 
10,000-11,000 ft. Lat. 26° 12’ N. Margins of maple forests. 
Shrub of 9-12 ft. Flowers fragrant fleshy rose-pink, with few 
markings. G. Forrest. No. 13,789. May 1917. 
A species which in the outward appearance of its detersile 
indumentum recalls Rh. floccigerum, Franch., but whilst the 
upper stratum of indumentum in the two species is formed of 
similarly constructed hairs, the under stratum here is glandular, 
in Rh. floccigerum consists of vesicular rosette-hairs. It is not 
really an ally of Rh. floccigerum, wanting the caudate scale- 
leaves to the foliage-bud seen in that species, having a non- 
fleshy not tubular-campanulate corolla, and the ovary is 
glandular not floccose, the style glandular not glabrous or 
nearly so. The well-developed calyx, the glandular ovary, and 
glandular style may lead one to the Souliei series, but the 
foliage and its indumentum are very different. From the 
general facies of the plant and its inflorescence one might be 
excused for taking it at first glance to be a relative of Rh. Trail- 
lianum, G. Forrest et W. W. Sm. of the Lacteum series, which 
it is not. 
Rhododendron dimitrum,* Balf. f. et Forrest. 
Small shrub not 2 m. high with short straight branches 
some 2.5 mm. in diameter when a year old and then glab- 
* diputtooc, with double cap—in allusion to the very large calyx.
