strikingly handsome. Mature bushes flower abundantly and the pure 

 white blossoms often flushed with pink are sweetly fragrant and very pretty 

 with their long, and prominent stamens and spreading reflexed corolla- 

 segments with a striking yellow blotch. 



This is a low-level Rhododendron, wide-spread in western Hupeh to 

 Mt. Omei and Mt. Wa in western Szechuan between elevations of from 

 4000 to 6000 ft. but nowhere plentiful. It also grows in southeastern 

 Szechuan and in the southwestern part of Hunan province. It is usually 

 found on cliffs in hot, moist valleys among an exuberant growth of shrubs, 

 mostly evergreen in character. Specimens collected on Mt. Omei and 

 Mt. Wa have thinner leaves which are much less obviously reticulated on 

 the upper surface than is the case with specimens from Hupeh. 



It was discovered by A. Henry between 1886 and 1888 on the borders 

 of Changyang and Patung districts and was introduced into cultivation 

 by seeds (No. 887) which I sent from the same locality to Messrs. Veitch 

 in the autumn of 1900; in 1910 I sent seeds (No. 4268) from Mt. Omei 

 to the Arnold Arboretum. Plants raised from the seeds sent in 1900 

 flowered for the first time in 1911 at Caerhays Castle.

 1910, 116.— Bean, Trees & Shrubs Brit. Isles, h. 386, (1914).— Millais, 

 Rhodod. 262 (1917). 



Bush from 1.5 to 3 m. tall with gray, slender, ascending-spreading 

 glabrous branches; winter-buds elongate, acute with paleaceous scales. 

 Leaves rigid-coriaceous, clustered into false verticils, ovate-lanceolate, 

 without petiole 5-10 cm. long, 2-4 cm. wide, acuminate, base more or 

 less cuneate, upper surface shining green, lower pale; petiole 0.5-1.2 cm. 

 long. Flowers fragrant, solitary and axillary but clustered to form fascicles 

 at the end of the last season's growth; pedicels glabrous, about 2 cm. long, 

 sheathed in many shining reddish brown paleaceous, imbricated, acute 

 bud-scales; calyx annular. 5-toothed or unequally 5-lobed, glabrous; 

 corolla deeply 5-lobed, pink, funnelform, 2.5-3 cm. deep, 4-5 cm. wide, 

 lobes rounded, spreading from a narrow tube, posterior lobe spotted with 

 brown; stamens 10 of unequal length, longest as long or nearly as long 

 as corolla, filaments flattened, slightly villose near base, anthers broadly oval; 

 pistil glabrous, exceeding the stamens, ovary oblong, 0.7 cm. long; style 

 slender, curved, stigma Iobed. Fruit cylindric, about 3 cm. long, 0.5 cm. 

 broad, furrowed. 



This is a twiggy shrub seldom more than 6 ft. tall and very distinct 

 with solitary, pink, deeply lobed flowers, the lobes spreading from a short 

 narrow tube. It is the rarest of the Hupeh species, being only known 

 from one locality in the Patung district where it grows with other shrubs 

 and trees in rocky places between elevations of 5000 and 6500 ft. In 

 1917 it was found on the mountains of northern Kwangtung by Rudolf 

 Mell. It was discovered by me late in April, 1900, and in the autumn 

 of this same year I sent seeds (No. 886) to Messrs. Veitch. All the plants
