92 BALFOUR—NEW SPECIES OF RHODODENDRON. 
butterfly-shape white flushed violet with a faint yellow 
tinge on posterior side of limb and there spotted with pale 
ochre-brown spots sparsely lepidote and puberulous outside 
posteriorly ; tube funnel-shaped concave in front and there 
4 mm. long, convex on back grooved and longer, expanding into 
a concave patent limb, puberulous inside at base, 5-lobed two- 
lipped upper lip three-lobed ; lobes rounded or elliptic or oblong 
undulate sub-erect, posterior smallest about 1.5 cm. long 1.3 
broad, antero-lateral divergent slightly larger and narrower 1.7 
cm. long 8mm. broad. Stamens 10 unequal longer than corolla, 
longest about 3.7 cm. long with oblong anther 2 mm. long, 
shortest about 1.5 cm. long with nearly globose anther 1 mm. 
long; filaments slender white or tinged violet wider to base, 
base glabrous over 3-4 mm. to above ovary, then filaments on 
posterior side villous to mouth of corolla-tube, on anterior side 
puberulous only ; anthers pink. Disk puberulous. Gynaeceum 
about 4 cm. long or more exceeding the stamens and corolla ; 
ovary conoid truncate about 3 mm. long 2 mm. in diameter 
green but glaucous, lepidote with nearly contiguous whitish 
peltate scales, a few hairs at summit; style glabrous long 
thin white not swollen below the small green lobulate narrow 
lipped stigma. 
Szechwan. Wilson. No. 1220 in part. 
_ One of the several species which have appeared in cultiva- 
tion under numbers of Wilson’s collections assigned to Rh. 
Davidsonianum, Rehd. et Wils. and other members of the 
Triflorum series. Rh. lochmium came under No. 1220. That 
number ought to be Rh. villosum, Rehd. et Wils. a very different 
plant. Its nearest relations in the Triflorum series are Rh. 
polylepis, Franch. and Rh, Searsiae, Rehd. et Wils., and with these 
it forms a distinct group easily distinguishable from all other 
species in the series by foliage-characters :—Oblong chartaceous 
sharp-pointed leaves with very convex and bullate dark- 
coloured lepidote upper surface and densely lepidote under 
surface, the tip always depressed and the whole leaf more or 
less deflexed. The young leaves convolute in bud become 
revolute as they expand. The convexity of the upper surface 
is brought about by the sides of the lamina on each side of 
the midrib curving upwards abruptly from it leaving it in a 
groove and then curving downwards towards the margin. 
Large though the Triflorum series now is—including some 30 
or more species,—no one of the other members can be con- 
fused with the three species forming this little Polylepis set 
within the series. The species are easily distinguished from 
one another both by vegetative and flower-characters, thus :—
