II. Calyx cupular, hemispherical or scutelliform, obsoletely lobed. Corolla campanulate, five-lobed. Stamens 
10—16. Ovary 6—16 celled. Large flowering shrubs, with very glabrous leaves. 
R- AucJclandii (J. D. H.). Plate 11.—A noble species, four to eight feet high, with large leaves, and beads of 
few large broad shallow flowers, white, tinged with pink, and veiny. Elevation 7 to 9,000 feet, in the drier 
valleys. This proves to be the R. Griffithii of Wight, which name must take precedence of R. Aucklandii. 
R. Thomsoni (J. D. H.). Plate 12.—A magnificent hush, 8 to 10 or 15 feet high. The leaves are broad, flat, 
and rounded, and the campanulate flowers are of a deep blood-red colour, very brilliant. Elevation 11 to 13,000 
feet. R. candelabrum (J. D. H.); plate 29; a very handsome hush, with the flowers sulphur-coloured, edged 
with rose, and growing at a similar elevation, is now found to be merely a variety. 
III. Calyx subfoliaceous, five-partite, lobes submembranaceous. Corolla infundibuliform or campanulate, tube 
elongated. Stamens 10—18. Ovary 5—6 celled. Shrubs, frequently epiphytes, leaves lepidote beneath. 
R. Dalhousice (J. D. H.). Plates 1 and 2.—This is the finest of the race. Its form an epiphytal shrub, six to 
eight feet high, with moderate-sized leaves, and very large lily-like fragrant white blossoms, which in age assume 
a delicate roseate tinge. Elevation 6 to 9,000 feet, in humid forests of the temperate zone. 
R. JEdgewortliii (J. D. H.). Plate 21. A beautiful shrub, of moderate size, often pendulous from trees or 
rocks, having large ferruginous leaves, downy beneath, and producing large white flowers two or three together. 
Elevation 7 to.9,000 feet, in damp temperate forests. 
R. barbatum (Wallich.). Plate 3.—A tree forty to sixty feet high, bearing compact heads of rose-coloured 
flowers. Elevation 9 to 11,000 feet, in damp forests of the temperate zone. R. lancifolium (J. D. H.); plate 4 ; 
a shrub six to eight feet high, found at 8 to 10,000 feet elevation, is considered a variety of this supei’b species. 
R. ciliatum (L D. H.). Plate 24.—A small hairy shrub, two feet high, with largish leaves, and small clusters 
of purplish flowers. Elevation 9 to 10,000 feet, in temperate rocky valleys of the interior. 
R. glaucurn (J. D. H.). Plate 17.—A beautiful little shrub, averaging two feet high, the leaves small, oblong, 
very glaucous beneath, the flowers in comparatively large clusters, of a lively rose pink. Elevation 10 to 12,000 
feet. 
R. pumilum (J. D. H). Plate 14.—A very elegant little plant, the smallest of the Sikkim species, rooting 
amongst moss, growing three or four inches high, and bearing pretty pink flowers on long stalks. Elevation 
12 to 14,000 feet. 
IV. Calyx small or obsolete, rarely five-toothed, lobes equal. Corolla campanulate, or with the limb contracted 
below its base, and subinfundibuliform. Stamens 10. Ovary 5—10 celled. Shrubs sometimes lepidote. 
R. Campbellicc (J. D. H.). Plate 6.—A fine tree, the characteristic species of Darjeeling. The rose-scarlet 
flowers are in close round heads ; the leaves are narrow and rusty beneath. Elevation 9 to 10, or 11,000 feet, in 
the temperate valleys. This is the R. nilagiricum of the Botanical Magazine; and is now considered only a 
variety of R. arboreum. 
R. Wtallichii (J. D. H.). Plate 5.—A shrub, eight to ten feet high, with broad elliptical leaves, and flowers of 
a lilac-rose colour. Elevation 11 to 13,000 feet. This and the following are now ranked by Dr. Hooker as 
varieties of R. campanulatum. 
R. cemginosum (J. D. H.). Plate 22.—A handsome shrub, growing four feet high, with blunt leaves, rusty 
beneath, and large heads of lilac rosy flowers. Elevation 12 to 14,000 fe,et. 
R. Wightii (J. D. H.). Plate 27.—A very handsome shrub, of ten feet high, with rather large flat leaves, 
rufous beneath, and large heads of pale yellow flowers, marked with red spots. Elevation 12 to 14,000 feet, 
in the alpine valleys, where it is the most prevalent species. 
R. lanatum (J. D. H.). Plate 16.—A neat-looking large shrub ; the young bark, stalks, and under part of the 
leaves covered with white cottony tomentum; the flowers are sulphur-coloured, spotted with red. Elevation 
10 to 12,000 feet. 
R. fulgens (J. D. H.). Plate 25.—A very showy shrub, growing four feet high, with broad foliage, woolly and 
purplish beneath, and dense round heads of the richest blood-red' flowers. Elevation 12 to 14,000 feet, in the 
valleys of the interior. 
R. campylocarpum (J. D. H.). Plate 30.—A handsome pale-flowered bush, of about six feet high, which, 
from its graceful and delicate inflorescence, Dr. Hooker regards as the most charming of the Sikkim species, 
claiming precedence over its more gaudy congeners. The leaves are short and broad, and the flowers are of a pure, 
spotless sulphur-colour, produced in large heads. Elevation 11 to 14,000 feet. 
V. Calyx short coriaceous, five-lobed or toothed, the upper generally elongated, sometimes subulate. Corolla funnel- 
shaped, tube narrowed. Stamens 10—20. Ovary 5—10 celled. Shrubs with leaves lepidote beneath. 
R. Macldcni (J. D. H.). Plate 18.—A fine shrub, six to eight feet high, with sharp-pointed leaves, bright 
ferruginous beneath, and heads of three or four large white long funnel-shaped blossoms. Elevation 6000 feet, in 
the drier temperate valleys. 
R. cinnabarinum (J. D. H.). Plate 8.—A small, and, according to Dr. Hooker, very elegant shrub, with small 
pendulous cinnabar-coloured flowers. Elevation 10 to 12,000 feet. It is considered poisonous to cattle and goats,
