BALFOUR—NEW SPECIES OF RHODODENDRON. 125 
of the successive annual shoots; outer scale-leaves brown 
crustaceous keeled and mucronulate glabrous outside, inter- 
mediate longer oblong shortly ciliate densely lepidote outside, 
innermost greenish somewhat membranous narrowly oblong- 
oval obtuse and ciliate carried up on elongating shoot. Leaves 
of a year present when those of succeeding year are developed, 
petiolate as much as 4.5 cm. long ; lamina thinly leathery oval 
or oboval as much as 4 cm. long 1.7 cm. broad, apex obtuse or 
rounded with short conspicuous red tuberculate mucro, margin 
setulose, base obtuse or rounded ; upper surface olive-green mat 
with grooved midrib and primary veins about 8 on each side 
hidden most glabrous ; under surface paler somewhat glaucous 
setulose all over copiously on the raised pinkish midrib (primary 
veins concealed) also densely lepidote with brown infiltrated 
superficial discontiguous concave nearly uniform scales without 
conspicuous fringe the distance between the scales less than or 
occasionally slightly more than diameter of scales about 4~5 
scales ina sq. mm. ; petiole about 5 mm. long clad like the stem. 
Flowers in a 2-flowered terminal umbel; bracts quite like the 
scale-leaves of the foliage-buds; bracteoles linear-clavate a 
little more than I cm. long lepidote towards top and setulose ; 
pedicels as much as 3 cm. long green lepidote and bristly ex- 
panded into a cup below the calyx. Calyx large longer than 
ovary about 7 mm. long cut to the base into 5 green lobes ; 
lobes unequal oblong or lanceolate obtuse or acute lepidote with 
large white scales outside and densely setulose all over back and 
margin. Corolla yellow spotted copiously posteriorly oblique 
about 2.5 cm. long, puberulous and lepidote outside, puberulous 
inside ; tube in front short about 5 mm. long expanding into a 
broad limb with 5 unequal lobes, posterior lobe smallest rounded 
about 1 cm. long and broad, antero-lateral elongated oval about 
1.5 cm. long 8 mm. broad entire. Shortest stamens about I cm. 
long; filaments stout villous some distance above the base. 
Disk glabrous. Gynaeceum over 2.5 cm. long; ovary short 
thick cylindric truncate about 4 mm. long, shorter than the style 
densely lepidote with white scales and setulose with many bristles 
those at top forming a crest encircling base of style ; style thin 
delicate epilose more or less lepidote. 
W. Yunnan. Summit of the Jangtzow Shan, Shweli-Sal- 
ween divide. Lat. 25° 15’ N. Alt. 11,000-11,500 ft. Open 
exposed situations on cliffs. Shrub of 1 ft. Flowers pale 
yellow. G. Forrest. No. 18,143. June rgtg. Rare. 
Another and very distinct member of the Trichocladum series 
distinguished readily from other species of the series by the longer 
calyx, the ovary clad with bristles in addition to scales and the 
lepidote style. The material that has come home so far has only
