margin and cuneate base, dull green above, paler beneath 

 but witliout marked glaucous bloom, when young clad on 

 both sides, but more densely below, with long intricate pale 

 brownish hairs and also lepidote with pale shining super- 

 ficial discontiguous scales ; older leaves have lost more or 

 less the hairs and scales from the upper side and are 

 lepidote below with some hairs on the base of the midrib 

 and covering the petiole — the midrib and primary veins and 

 the veinlets tend to become a dark red colour and are not 

 prominent ; petiole, at most 4 mm. long, is densely coated 

 with long intricate hairs and more or less lepidote. The 

 flowers are grouped in terminal umbels of about 3 flowers 

 and are precocious. Bracts are soon deciduous. Pedicels 

 are at most 1*3 cm. long with hairs and scales, and expand 

 into the calyx, which is so densely bearded its surface is 

 hidden. Calyx lobes 5. Corolla yellow, about 2 cm. long, 

 narrowly campanulate lepidote outside and pilose ; the tube 

 is about 1 cm. long and is pubescent inside, the ample limb 

 has 5 rounded spreading entire lobes about 1 cm. in diameter. 

 The stamens are 10 shorter than the corolla with large 

 ovoid anthers, and the filaments of the posterior stamens 

 whitely villous about the middle, filling up the mouth of 

 the corolla above the ovary, the others are puberulous at 

 the base. The ovoid ovary, about 3 mm. long, is lepidote 

 and also bears long twisted hairs, especially at the top ; 

 style more or less declinate is about 8 mm. long and quite 

 glabrous ; stigma lobulate. 



Yunnan : — Shweli-ISalween divide, Lat. 25° 30' N. 

 Alt. 10,000 ft. Shrub of 2-4 ft. Flowers precocious, 

 canary-yellow. Open stony slopes on the margins of 

 thickets. C. Forrest. No. 12,066. June 1913. 



This species is without doubt the representative on the 

 Shweli-Salween divide of Rli. tricliocladum, Franch., which 

 is spread over the Tali Range. The Shweli-Salween plant 

 differs from Rh. trichocladum, Franch., in habit. It forms 

 a somewhat intricately branched small shrub wanting the 

 stouter virgate twigs of Jl/i. irlcliocladuin, Franch. Then 

 the hair indumentum here is always lanate in type, not 

 hispid. Furtliei', the calyx has a dense beard of hairs 

 coating it, and the corolla has hairs on the outside in 

 addition to scales.
