ERICACEAE. — RHODODENDRON 507 
deciduis, calyce plerumque lobis omnibus ovatis subaequalibus 1.5 
mm. longis, stylo glabro pallide purpureo. 
Western Szech’uan: north of Tachien-lu, Ta-p’ao-shan, moor- 
lands, 4300 m., July 7, 1908 (No. 34672). 
Distinguished from the type chiefly by the more fastigiate habit, the nearly 
equal calyx-lobes and the glabrous style. 
Rhododendron ramosissimum Franchet in Jour. de Bot. XII. 264 
(1898). 
Western Szech’uan: vicinity of Tachien-lu, moorlands, alt. 3600- 
4600 m., June, July and October 1908 (Nos. 3468, 3469; bush 0.3-1 m., 
tall, flowers dark purple). 
Our specimens differ from Franchet’s description in the slightly pubescent 
mouth of the corolla-tube. In No. 3468 the leaves are often oblong-lanceolate; 
and the flowers are either solitary or in pairs. Franchet compares this species 
With his R. intricatum; to us it would appear more closely allied to R. polycladum 
Franchet. 
Group c. 
_ Stamens nearly as long as the corolla; style longer than the stamens; corolla

Perulis paucis rotundatis extus in medio dorsi lepidotis ceterum
