Mag'or, of Lamellen, Cornwall, wlio kindly vsent specimens to 

 Kew, According to Forrest, wlio found it in shady, moist situa- 

 tions on tlie eastern flank of tlie Tali Range, Western Yunnan, 

 at 11,000-12,000 ft. altitude, it is a shrub 15 to 20 ft. high. 

 Young stems stout, scaly. Leaves 2^ to 6 ins. long, 1 to 2 ins. 

 wide, oval or narrowly obovate, coriaceous, dark glossy green and 

 wrinkled above, rather glaucous beneath, but thickly sown with 

 shining brown scales; petiole fleshy, very scaly, up to 1 in long. 

 Flowers in a terminal cluster of four to seven ; corolla funnel- 

 shaped, 3 ins. long, tive-lobed (the lobes ovate-orbicular), creamy 

 white to rosy white, fleshy in texture, scaly outside. Stamens up 

 to 20, included in the corolla. Ovary and style scaly, the latter 

 2 to 2^ ins. long. Calyx five-lobed; lobes ovate or elliptical, 

 reaching almost to the base, rounded at the apex, |- in. long, 

 almost transparent; peduncle thick, | to f in. long. 



li. crassum is undoubtedlv very closely allied to R. Maddeni, 

 and is probably no more than a geographical form of that species. 

 The chief distinction appears to be in the lobes of the calyx, which 

 are larger and broader than in R. Maddeni, although equalled in 

 length by those of the Manipur form of the spec " — - - 



var. ohtitsifoliuvi. It will probably be hardier.

This species first flowered at Kew in May, 1913, and has flowered 

 in several collections during the past spring. The plants that 

 have blossomed are mostly about 1 ft. high, but Wilson found it 

 on Mount Omi, in Western China, 10 ft. high. The plant is 

 glabrous, except that the leaves are freely sprinkled beneath with 

 small scales. Leaves clustered at the end of the shoot, very 

 unequal in size, narrowly oval or obovato, varying from 1 to 4 ins. 

 long and from \ to 1\ ins. wide; they are dark green above, paler 

 beneath, and of a peculiarly hard, leathery texture. Flowers 

 borne in a terminal cluster, sometimes verv numerous, sometimes 

 only six to ten, but then larger. The funnel-shaped corolla is 

 |- to f in. long, deeply five-lobed, and varies in colour from creamy 

 white to clear yellow. Calyx-lobes oblong, r^ to ;^ in. long, 

 ciliate and slightly scaly ; stamens ten, white, downy at the base, 

 anthers brown ; ovary scaly ; style glabrous, exserted. \ 



The Rev. Ernest Faber appears to have first collected this 

 rhododendron on Mount Onii at 4000 ft. altitude about 1886, but 

 the plants in cultivation were raised from seed sent home by 

 Wilson in 1909. It seems to be very hardy, and likely to prove 

 a useful addition to flowering evergreens, although perhaps not a 

 very showy one. 



Rhododendron longistylum, Rehder ^ Wilson. 



Baised from seeds collected by Wilson in 1908, and sent to 

 Kew from the Arnold Arboretum, plants of this new species 

 flowered at Kew for the first time last spring. According to the 

 collector it is a shrub varying from 2 to 6 ft. in height, and 



Western Szechuen, where it is fully

exposed to the sun. Its young shoots are glabrous and sparsely 

 lepidote, and bear leaves over their whole length. Leaves 

 leathery, oval, oblong, or obovate, 1 to 2 ins. long, ^ t o f in. wide.
