122 BALFOUR—NEW SPECIES OF RHODODENDRON. 
small lobulate stigma at the centre of its extremity. Capsule 
about I cm. long 3 mm. in diameter dehiscing to base by 5 valves. 
S.W. Szechwan. es around Mu-li, valley of the 
Litang River. Lat. 28°12’ N. Alt. 1z,o00 ft. Open situations 
in and on the margins Be i forests. Shrubof4-5ft. Flowers 
white faintly tinged rose. G. Forrest. No. 16,249. June 1918. 
Rh. ophaeum is one of the small-flowered species of the 
Triflorum series, using that designation in its widest sense. Its 
nearest allies are Rh. longistylum, Rehd. et Wilson and Rh. 
Hanceanum, Hemsl.—two of Wilson’s species from Szechwan, 
and both known in wild specimens in an imperfect condition. 
They are common plants now in cultivation and their features 
in living specimens are well known. Rh. hypophaeum is easily 
distinguished from both these species by its less leathery leaves 
smooth not rugulose on the upper surface and with closer-set 
scales on the under surface. Then the inflorescence is a few- 
flowered umbel solitary and terminal whilst in the species 
named the inflorescence is essentially racemose with many 
flowers although where there are only a few flowers the umbellate 
form appears.

A stiffly branched shrub reaching 2 cm. in height with few
