R. Jenk'msi. — This species, according to a specimen with- 

 out flower or fruit, in the herbarium of Sir. W. Hooker, was 

 found by the late Mr. Griflith on the Khasya Hills. As a 

 species, it is allied to R. Maddenf, of Dr. Hooker; and these, 

 along with R. sparsiflorum, R. camelliaflorum, R. lucidum, 

 and R. calophyllum, have a very peculiar aspect, all agreeing 

 in their smooth lepidote leaves, and succulent texture. Mr. 

 Booth supposed, from the examination of the buds, that R. 

 Jenkins/ would have yellow flowers, the specimens having 

 been collected in the month of December. It is named in 

 honor of Major Jenkins of the East India Service. If, as is 

 probable, this species has large yellow flowers, like R. Mad- 

 deni, it will be one of the most distinct exhibition plants in 

 the tribe. 



R. lo7igifdlhim. — A magnificent foliaged plant, discovered 

 in the forest of Bootan, on the slopes of the Oola Mountains, 

 at an elevation of 6,500 to 7,500 feet above the sea level ; 

 the leaves twelve to eighteen inches long, three to five inches 

 wide in the middle ; at first pubescent, at length smooth, or 

 nearly so ; gradually narrowed downwards ; obovate, lanceo- 

 late, silvery, and whitish beneath. To all appearances, near- 

 ly hardy in this climate. 



R. Keysi. — A hardy distinct shrub, growing to the height 

 of two or three feet, on the mountains of Bootan, at an ele- 

 vation of 9,000 to 10,000 feet above the sea level, on the 

 summit and northern ridges of the Lablung, forming low 

 thickets, accompanied by Gaultherias and Yews above the range 

 of R, Hookerz and R. Falconer/; leaves 2\ to three inches long, 

 about an inch wide ; coriaceous, and smooth ; beneath, as 

 well as capsule, almost covered with brown, circular, resinous 

 scales. Corymb, compounded of three or four branchlets, 

 each containing five or six flowers. Corolla (judging from 

 the withered remains only) tubular ; the border, five-lobed 

 and reflexed ; the segments ovate, obtuse. Rather aromatic, 

 from the resinous scales with which the leaves are clad be- 

 neath. In its native hills it grew amidst snows two or three 

 feet in depth. It is allied to Dr. Hooker's R. virgatum ; the 

 flowers, as in that species, axillary, or below the summit of 

 the branch. A shrub very distinct in habit.
