Bush from 1-7 m. tall (usually from 3 to 5 m.), wide-branching, the 

 branches moderately stout, with or without a gray scurfy covering when 

 young; winter-buds ovoid with glandular, ciliolate scales. Leaves coria- 

 ceous, glabrous, elliptic to oblong, sometimes broadest above the middle, 

 without petiole 5-12 cm. long, 2.5-5.5 cm. wide, rounded, apiculate, 

 base rounded or slightly subcordate, rarely oblique, upper surface dark 

 green, lower pale green, midrib stout, prominent and clothed with floccose 

 gray tomentum on lower surface; petiole stout, 1-2.5 cm. long, glabrescent. 

 Flowers 6-12 in a terminal umbellate raceme; rhachis 1.5-3.5 cm. long 

 and with pedicels densely clothed with rufous-gray villose hairs; pedicels 

 ascending-spreading, 1-2.5 cm. long; calyx villose, saucer-shaped, with 

 5 small, unequal triangular teeth; corolla 5-lobed, white or pale pink with 

 posterior blotch or spots of maroon near base, campanulate, 2.5-4.5 cm. 

 deep and broad, lobes short, spreading, rounded, often emarginate; 

 stamens 10, of unequal length, shorter than corolla, filaments flattened, 

 slightly villose at base, anthers oval, very dark; pistil as long as corolla, 

 ovary narrow-ovoid, clothed with rufous-gray villose pubescence, style 

 reddish, filiform, stigma capitate. 



This species is distinguished by the shape of its ample leaves, the 

 midrib on the under surface broad and covered with floccose hairs, and by 

 its villose rhachis, pedicel and ovary. The bell-shaped flowers are arranged 

 in compact rounded trusses which terminate every shoot. It is a wood- 

 land plant, wide-spread and common between elevations of from 5000 to 

 10000 ft. throughout western Hupeh and contiguous Szechuan. It is 

 most abundant in forests of Abies Fargesii Franch. associated with Arun- 

 dinaria Murielae Gamble, above 8000 ft. altitude in Fang district. It is 

 indeed a high-level species and with R. Fargesii Franch. is found at 

 greater altitudes than any other Rhododendron in Hupeh. In a wild 

 state it is in flower from mid-May until mid-June. Usually it is a bush 

 from 8 to 15 ft. tall and broad but I once saw it 30 ft. high with a trunk 

 2 ft. in girth being quite tree-like in appearance. 



This Rhododendron was discovered round Tchen-keou-ting by P£re 

 P. Farges sometime between 1891 and 1894; it was introduced into culti- 

 vation by seeds (No. 944) which I collected in the district of Changyang 

 in December, 1900, and sent to Messrs. Veitch. All the plants in cultiva- 

 tion are of this origin. It flowered for the first time in gardens at Caerhays 

 Castle. In Cornwall it flowers in late March and early April but in colder 

 districts it will be found to blossom later. It is a hardy, sturdy species of 

 good habit and abundant foliage. Though not one of the finest it is a very 

 floriferous Rhododendron possessed of much quiet charm.
