EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. IQl 



large shrubby kinds, and with R. Edgeioortliii and R. j^emhihnn 

 among- others. 



19. R. campylocarpum. — Distribution and range: East 

 Nepal and Sikkim — 11,000 to 14,000 feet — common 

 in alpine valleys. 



A small bush, averaging 6 feet in height, rounded in form, of 

 a bright green hue, and which, when covered witli its delicate 

 inflorescence, claims precedence over its more gaudy congeners, 

 and has always been regarded by me as tlie most elegant of the 

 Sikkim Rhododendrons. The flowers have a pleasant honeyed 

 scent, and a resinous, sweet odour is exhaled from the stalked 

 glands of the leaf and flower stalks, calyx, and capsules. Leaves 

 on slender stalks, f of an inch long, coriaceous but not thick in 

 texture, 2 to 3^^ inches long, 1-| to 2 inches broad ; in all charac- 

 ters, except the evanescent glandular hairs and spherical buds, 

 undistinguishable from those of R. Tliomsoni. Flowers horizontal 

 and nodtling. Corolla campanulate, delicate in texture, tinged 

 of a sulphur hue and always spotless, nearly 2 inches long, broader 

 across the lobes, which are finely veined. The stalks of the 

 capsules radiate horizontally from the ends of the branchlets, and 

 the capsules them.^elves curve upwards in a semicircular arc ; 

 they are about an inch long, always loosely covered with stalked 

 glands. 



20. R. cinnaharinum. — Distribution and range : East 

 Nepal, Sikkim, and Bhotan — 10,000 to 12,000 feet— 

 in valleys and on the tops of mountains in very damp 

 regions. 



Under this species I include R. Roylei of the ' Sikkim Rhodo- 

 dendrons.' Neither of the figures give a good idea of the plant, 

 which forms a rather elegant bush, about 8 feet high, conspicuous 

 ill May and June from its elegant blossoms, which form very 

 loose and graceful heads of long pendulous flowers. The figures 

 of R. cinnuhariimm and R. Roylei are from stunted specimens 

 growing in very exposed situations ; the leaves are not usually 

 reticulated except under these circumstances, and are rather 

 membranous, of a glaucous green below and rather bluish above. 

 Flowers, 4 to 6 in a head, It inch long, witli a narrow, funnel- 

 shaped tube, and sliglitly spreading broad lobes, which are some- 

 times rather sharp at the point. It is universally considered ])()i- 

 sonous to cattle and goats : of the latter I have seen many die 

 from eating either of this or of a species of Andromeda, which 

 latter is notorious for this property tlu'oughout Sikkim, Nepal, 

 and N.W. Himalaya. If employed as fuel, the smoke causes the 

 eyes to inflame and the cheeLs to swell.
