REVIEW—THE RHODODENDRONS OF SIKKIM-HIMALAYA. 159 
** Along the north-east and exposed ridges only grow the R. Fal- 
coneri, in foliage incomparably the finest.” 
Dr. Hooker found eleven kinds in the district which he explored, 
but of these, one was the R. barbatum of Wallich, a species already 
known and introduced to England, and proved to be capable of bear- 
ing our ordinary winters in the climate of Chester; and another was 
the original A. arboreum of Smith, a kind so mixed up in our gardens 
with the various hybrid or cross-bred races to which it has given rise, 
as to be now seldom recognised. We now only give an abbreviated 
abstract of the description given by Dr. Hooker of the remaining species. 
Rhododendron Dalhousie (Lady Dalhousie’s Rhododendron).—A 
shrub six to eight feet high, growing on the trunks of large trees. The 
branches bear leaves and flowers only at their extremities. The leaves 
are few, four to five inches long, elliptic-obovate, somewhat leathery, 
and of a darkish green colour, paler beneath. The flowers grow from 
three to seven, in terminal umbellate heads, which spread wider than 
the leaves. ‘The blossoms are bell-shaped, very large, three inches 
and a half to four and a half long, and as much across the mouth, 
white, with an occasional tinge of rose, very fragrant, the odour par- 
taking of that of the lemon. The flowers in age become more roseate, 
and are sometimes spotted with orange. This is the noblest of the 
Rhododendrons. Native of Sikkim-Himalaya, at an elevation of from 
7,000 to 9,000 feet ; growing on the trunks of large trees. Flowers 
from April to July. 
Ethododendron lancifolium (lance-leaved Rhododendron).—A shrub 
six to eight feet high, with spreading tortuous branches. The leaves 
are produced chiefly at the ends of the branches; they are three to 
four inches long, oblong lance-shaped, very pointed, and of leathery 
texture, green above, tawny beneath. The flcwers’ grow in dense 
heads at the ends of the branches; they are of moderate size, bell- 
shaped, distinctly net-veined, and of a rich puce colour. Native of 
the interior: Sikkim-Himalaya. Flowers in May. 
te Rhododendron Wallichii (Dr. Wallich’s Rhododendron).—A shrub 
growing from eight to ten feet high, with rugged tortuous branches. 
The leaves are mostly confined to the apex of the ultimate branches; 
they are three to four inches long, almost exactly elliptical, full green 
and glabrous above, paler beneath, and having a remarkably neat 
appearance. The flowers are large and handsome, growing in terminal 
heads, having six to eight in each; they are rosy lilac with deeper 
rose-coloured dots within the base of the upper lobe; they are bell- 
shaped, with a spreading five-lobed limb. Native of the interior of 
Sikkim-Himalaya. Flowers ? 
Ethododendron Campbellie (Mrs. Campbell’s Rhododendron),—A 
tree growing frequently to the height of forty feet, forming a large 
spreading mass. The leaves are oblong-lanceolate, acuminate, leathery, 
green and smooth on the upper surface, and clothed beneath with a 
more or less deeply rufous or ferruginous tomentum. The flowers 
grow in dense compact heads, and are of a rich rosy-scarlet colour, 
spotted at the base of the upper lobe with dark spots, and around the 
bases of the remaining lobes with paler rosy spots. Native of Sikkim- 
Himalaya, frequent, growing at an elevation of from 9,000 to 10,000 
feet. lowers in April and May. 
Rhododendron Roylii (Dr. Royle’s Rhododendron),—A small shrub
