BALFOUR—NEW SPECIES OF RHODODENDRON. II9g 
lepidote and setulose. Flowers in 3—5-flowered terminal umbels ; 
bracts soon deciduous, unknown ; bracteoles short about 5 mm. 
long about .5 mm. broad strap-shaped lepidote outside, pilose 
and setulose on margin, hair-crested ; pedicels barely I cm. 
long strict divergent epilose sparingly lepidote reddened slightly 
expanded below the calyx. Calyx an undulate rim the protuber- 
ances fringed by large white peltate scales forming a conspicuous 
necklace-like ring below the corolla-tube. Corolla butterfly- 
shaped rose-coloured with brown spots posteriorly, about 3 cm. 
long puberulous inside, outside finely puberulous and with a few 
distant scattered white peltate scales; tube short apparently 
darker than limb thin slightly compressed with a median ridge 
on back of posterior petal and corresponding groove inside 
otherwise not conspicuously grooved ; 5 lobes unequal antero- 
lateral longer and narrower, posterior 1.5 cm. long r cm. broad, 
oblong-oval or ovate obtuse often somewhat undulate. Stamens 
Io unequal nearly equalling corolla, longest about 1.8 cm. long, 
shortest about 1.2 cm. long; anthers small ovoid about 2 mm. 
long ; filaments dilated at base and there glabrous over about 
2 mm., puberulous above to mouth of corolla-tube. Disk more 
or less puberulous. Gynaeceum longer than stamens and corolla 
about 3.3 cm. long; ovary cylindric truncate grooved about 
3.5 mm. long entirely covered by white imbricate peltate scales 
sometimes a few hairs at the top amongst the scales ; style red 
glabrous slightly swollen below the discoid lobulate stigma to 
which it forms a narrow crimson lip.

So many of the members of the Triflorum series are dis- 
tinguished one from the other by characters which, easily recog- 
nisable in the living plant, lose prominence in the dried specimen, 
that it is refreshing to have in this new species from S.W. 
Szechwan a plant of which dried specimens pronounce at once 
specific differentiation. Rh. hormophorum belongs within the 
Triflorum series to the set including Rh. chartophylium, Franch. 
and Rh. yunnanense, Franch. It is a plant the habit of which 
is in consonance with its described habitat—dry stony alpine 
pasture. Its stem appears to ramify in the soil under the stones, 
rooting and forming crowns from which aerial short shoots ascend, 
bare below and producing small tufts of leaves and trusses of 
flowers at the top. The community of such plants must form a 
scrub about a foot and a ha!f high after the fashion of old heather 
ona moor. The hairy bristly leaves have the hairs and bristles 
on the upper surface, whilst the under side has neither (excepting
