EAST NEPAL AND THE SIKKIM HIMALAYA INIOUNTAIXS, 93 



4. R. niveum. — Distribution and range: Sikkim — 

 10,000 to 12,000 feet — in moist valleys of the interior. 



This species forms a tree so similar to R. arboreum, that I 

 much doubt its being distinct. The snowy white down is pecu- 

 liar, as are the short capsules, and in my ignorance of the flowers 

 I rest its claims upon these characters alone. I have not recog- 

 nized young plants in cultivation. 



5. R. Dalhousice. — Distribution and range : East Nepal, 

 Sikkim, and Bhotan (Griffith)— 6000 to 9000 feet— 

 in Immid forests, generally growing on limbs of trees. 



The seeds of this species have germinated as freely as any, 

 and the young plants are making rapid progress in a cool moist 

 house. The young leaves are very hairy, which character and 

 their tenderness distinguish tliem. They most resemble R. cili- 

 atum, but the latter is more hairy, of a darker colour, and rigid 

 texture. — A straggling shrub, 6 to 8 feet high, generally growing, 

 like tropical Orchideae, among moss, with ferns and Aroide£e, upon 

 the limbs of large trees : the stems clothed wiih a reddish, papery 

 bark, the branches straggling in distant whorJs ; each branch 

 bearing its leaves and flowers only at the extremity. Leaves few, 

 spreading or reflexed, about 4^ to 5 inches in length, footstalk 

 about ^ an inch long, the margin plane (not revolute), the upper 

 surface darkish green, inclining to yellow ; beneath paler, dotted 

 with very small, scattered, rusty-coloured scales. Flowers 3 to 7 

 in a terminal, umbellate head, the spread of which is greater 

 than that of the leaves. Corolla 3^ to 4t inches long, and as 

 broad at the mouth ; at the contracted base of the tube are 5 

 deep pits. Lobes of the limb nearly equal, very broad, rounded, 

 waved, spreading. The flowers are white, with an occasional 

 tinge of rose, in size and colour almost resembling those of the 

 white Bourbon Lily (^Lilium candidum) ; in age they assume 

 a delicate roseate tinge, and sometimes become spotted with 

 orange, which rather adds to their beauty than detracts from it. 

 Tiiey are lemon-scented, and very fragrant. 



6. R. Griffithii. — Distribution and range : Bhotan and 

 Sikkim — 7000 to 9000 feet — in the valleys and ridges 

 of the interior only, where the climate is drier. 



It forms scattered bushes, 4 to 8 feet high, branching from 

 the base, where the trunk is 6 inches in diameter. Branches sub- 

 erect, copiously leafy. Bark smooth and papery. Leaves vari- 

 able in size and breadth, but large for the size of the plant, 4 to 

 10 inches long; margin plane, often tinged with yellow; upper
