BALFOUR—NEW SPECIES OF RHODODENDRON. 99 
surface dark blackish-green mat glabrous, midrib and primary 
veins (about Io on each side) raised red; under surface paler 
grey-green lepidote with small distant peltate raised unequal 
scales with thick umbo and hardly any fringe 1 or 2 scales in a 
sq. mm. also setulose more or less usually more densely so along 
raised red midrib and primary veins very densely towards base ; 
petiole red about 5 mm. long densely setulose. Inflorescence 
a 4~5-flowered terminal shortly racemose umbel, rhachis whitely 
pubescent and lepidote ; inflorescence-bud globose ; bracts and 
bracteoles deciduous as bud opens, outer bracts brown coriaceous 
ovate pointed glabrous, inner bracts coriaceous rounded con- 
volute densely lepidote and puberulous outside 1.3 cm. lon 
bracteoles linear about 1.3 cm. long shortly pilose below setulose 
towards base and lepidote towards apex; pedicels varying in 
length as flowers open successively at most 2.5 cm. long stiff 
stoutish dark green becoming dark purple very sparingly lepi- 
dote and setulose sometimes glabrescent swollen below the calyx. 
and there very dark-coloured. Calyx small at most 2 mm 
long usually less with 5 unequal membranous lobes rounded 
or semilunate sparingly lepidote outside or with a scale-fringe 
or glabrous, occasionally some minute marginal cilia. Corolla 
light yellow tinged green at base, spotted green posteriorly, 
campanulate from base barely 2 cm. long lepidote and epilose, 
outside puberulous, inside at base expanding into a spreading 
5-lobed limb; lobes rounded entire about 6 mm. long I cm, 
broad. Stamens 10 unequal, longest about equalling corolla, 
shortest about 7 mm. long; filaments stout greenish-yellow, 
glabrous at base often over 3 mm. in posterior stamens 
which are densely villous within corolla-tube the hairs stout 
long vesicular white, over about I mm. in others which have 
shorter and fewer hairs; anthers ochre-coloured about 2 mm. 
long. Disk glabrous, Gynaeceum shorter than corolla and 
longest stamens about I cm. long; ovary about 4 mm. long 
dome-shaped truncate shallowly grooved sparingly lepidote ; 
style stout glabrous deflexed broadly expanded at top below 
the lobulate stigma. Capsule short straight about 5 mm. long 
dehiscing from apex by 5 valves. 
Yunnan. Li-ti-ping. Lat. 27° 12’ N. Alt. 11,000 
ft. Open situations amongst scrub. Shrub of 2-4 ft. Flowers 
more or less precocious, light yellow tinged green at base. G. 
Forrest. No. 13,900. June 1917. 
One of the Trichocladum series. Its nearest ally is Rh. 
melinanthum, Balf. f. et Ward, from which it may at once be 
distinguished by the underleaf indumentum. In Rh. chlor- 
anthum the scales are distant seldom more than I mm., whilst 
in Rh. melinanthum they are much closer, some 4 to 5 in each
