100 CLIMATE AND VEGETATION OF 



16. Iv. campanidahnn. — Di.stribution and range: Ke- 

 maon, Nepal, Si/ikim, and Bhotcm — 10,000 to 14,000 

 feet — where it is abundant in all parts of Sikkini. 



This well-known species is commonly cultivated in our gar- 

 dens, and requires no particular description. It is wholly inodo- 

 rous, and the flowers are very variable in colour, being of a 

 deeper or paler lilac, often spotted inside the corolla. The variety 

 I liave called Wallicliii is nearly destitute of wool on the under- 

 surface of the leaf, and 11. (erugiuosum, another variety, diflers 

 only in the purple capsules and curious verdigris-green colour of 

 the young foliage. This and the following are the great orna- 

 ments of regions above 12,000 feet, where they often cover 

 the flanks of the valleys with their rich green foliage and gaudy 

 blossoms. 



17. H. fitlgc?h<!. — Distribution and range: Sihkim — 

 12,000 to 14,000 feet— in the valleys of the interior. 



This superb species vies with R. Thomsoni in the colour of its 

 dense capitula of flowers. The foliage entirely resembles tiiat of 

 E. Ulacinum, the flowers those of R. arbor eum. 



18. 'R, lanatum. — Distribution and range: East Nepal 

 and Sikkim—lOfiOO to 12,000 feet. 



A large shnib or small tree, with the trunk 6 inches in dia- 

 meter at the thickest part, irregularly and repeatedly branching ; 

 branches much gnarled and bare of leaves, covered with a dark- 

 coloured rugged bark, very different from the prevailing beauti- 

 ful papery clothing of the geiuis ; where it breaks off from the 

 younger branches, however, it exposes a delicate pink inner bark, 

 whilst the branchlets are densely clothed with a soft, appressed 

 cottony wool. The latter, generally of a white or tawny colour, 

 is uniformly spread over the leaf-stalks, flower-stalks, ovary, and 

 the under surface of the leaves, also extending to the upper sur- 

 face, along the midrib, and to the very base in a less degree. 

 The leaves are confined to the ends of the branches, 3? to 5 

 inches long, by about 2 inches broad, obovate or elliptical, ob- 

 tuse, the colour a full yellow^ish green. Leaf-stalks short, thick, 

 very woolly. Heads terminal, of 6 to 10 rather large, inclined 

 flowers. Flower-stalks H inch long, thickened. Corolla ochro- 

 leucous or pale sulphur-colour: the tube broad-campanulate (like 

 that of R. Wightii) ; within, above, and 3 of the upper lobes in 

 part sprinkled with red dots ; limb 2 to 2+ inches across, of 5 

 nearly equal, very spreading, rounded, entire, obtuse lobes. In 

 the dense wool on the under side of the leaves, this species may 

 be compared with R. fulgens and R. ceruginosum among the
