tree, about 35 feet in height, with a white, smooth hark. The 

 leaves are from 1 to 3 feet long and from 8 to 10 inches broad, 

 deciduous, oblong-obovate, somewhat panduriform, cordate at the 

 base, under surface w^hite, glaucous. Flowers white, and purple at 

 the base, sweet-scented, 8 to 10 inches in diameter ; petals 6 to 9, 

 ovate. Xative of North America, in moist, swampy, shady places, 

 about Lincolton in Upper Carolina and in the deep forests of 

 Tennessee.

 A very lofty tree, inhabiting the dense forests of Sikkim and 

 Bhotan and at altitudes of 8,000 to 10,000 feet in the Eastern 

 Himalaya. The leaves are deciduous, elliptic-ovate or oblong- 

 ovate, or acuminate, membranous, 4 to 12 inches long by 2 to 4 

 inches wide, glabrous aljove, glaucous, pubescent or silky beneath, 

 base cordate, rounded or oblique, petiole 1 inch. Flowers 6 to 10 

 inches in diameter, very fragrant, pink, occasionally white. 

 Hooker and Thomson remark that this superb species, which is so 

 conspicuous a feature in the scenery of Sikkim (the trees attaining 

 a height of about 150 feet) will aptly record the services of Dr. 

 Campbell, resident at Darjiling, in connection with the rise and 

 progress of that important place and also his many contributions 

 to our knowledge of the geography and productions of the 

 Himalaya. It flowers in the month of April, when quite leafless. 

 The shape and clothing of the leaves varies more than is usual in 

 the genus : on very young trees the leaves are quite glabrous, and 

 much more membranous than on the adult plant. 



31. glohosa, Hooker and Thomson, Flora Indica, i., p. 77. A tree 

 of about 40 feet in height, native of the interior, temperate ranges 

 of the Sikkim Himalaya at altitudes of 9,000 to 10,000 feet. The 

 branches are brown ; when young, tomentose ; when old, glabrous. 

 Leaves 5 to 9 inches long by 3 to 6 inches wide ; the nerves of the 

 under surface are tomentose. Flowers 4 to 5 inches in diameter, 

 globose, white, fragrant. Peduncles terminal, single, densely 

 tomentose. This is the species which attains the greatest eleva- 

 tion and penetrates furthest into the interior of the Himalaya.
