160 REVIEW—-THE RHODODENDRONS OF SIKKIM-HIMALAYA. 
with oval or elliptic leaves, three to four inches long, clothed beneath 
with an ochraceous-brown pulverulent substance. ‘The flowers grow 
from four to eight in a loose head; they are campanulate, with a 
slightly spreading limb of five rounded lobes, ending in an acute point; 
the colour is brownish red, the lobes of the limb just tipped with 
bluish green; in its unexpanded state the corolla is iridescent with 
blue; the tube of the corolla is striated within. Native of Sikkim- 
Himalaya, on the mountains of the interior. Flowers in Apriland May. 
Rhododendron cinnabarinum (cinnabar-leaved Rhododendron).—A: 
small shrub with slender tortuous branches, bearing leaves from two 
to three inches long, of an acutely ovate-lanceolate form, green and 
glabrous above, and beneath often reddish and dotted with little 
scales. The flowers are small, funnel-shaped, with five spreading 
rounded acute lobes; they grow in small compact heads, and are of a 
cinnabar colour. Native of the ‘“ Sub-Himalaya mountains, interior 
of Sikkim.” Flowers in April and May. 
Rhododendron eleagnoides (oleaster-leaved Rhododendron),—A 
small much-branched shrub, with small obovate-trapezoid leaves, 
covered with minute silvery leprous scales ; these leaves are a quarter 
of an inch long, plane, leathery. No examples of this curious little 
species were found in flower, It is a little alpine, growing in the 
vicinity of the snow; and is ‘apparently single flowered, and caly- 
culate.” Native of the mountains of Sikkim-Himalaya, at an eleva- 
tion of from 14,000 to 15,000 feet. 
Rhododendron argenteum (silvery Rhododendron).—A fine tree 
erowing thirty feet high, with spreading branched trunks. The 
leaves are very beautiful in the young state, enveloped at first in 
pinkish-brown scales, which are so large and closely imbricated as to 
resemble the cones of some species of pine ; at first the leaves are erect 
and silky ; when mature they are very large, six inches to a foot long, 
obovate-oblong, leathery, green above and silvery-white beneath. ‘The 
flowers grow in large terminal heads; tney are broadly campanulate, 
two to three inches long, with a limb of five short bilobed segments, 
spreading, two to two and a half inches in diameter; they are always 
white, unspotted, very handsome, and only second in size to 
F. Dalhousie. Native of Sikkim-Himalaya: summit of Sinchul, 
Sirradah, and Tonglo, at an elevation of from 8,000 to 10,000 feet. 
«On Sinchul, the higher parts of the mountain, at from 8,000 to 9,000 
feet of elevation, are more or less clothed with it: on Tonglo, as it 
approaches 10,000 it is suddenly replaced by 2. Falconeri.” 
Rhododendron Falconeri, Hooker fil. (Dr. Faleoner’s Rhododendron). 
—A fine tree growing thirty feet in height, the trunks often two feet in 
diameter, the branches few and spreading. The young leaves are 
clothed with velvety down, and when in the bud are concealed by 
downy glutinous scales. When perfect, they are from eight inches to 
a foot in length, obovate-elliptic and obtuse, very coriaceous, glossy 
green above, and beneath, except on the thickly-netted veins, clothed 
with a dense pale-ferruginous down. The flowers grow in heads of 
moderate size, but composed of numerous rather small but densely 
placed flowers, which are white, bell-shaped, with a limb of ten 
rounded lobes. One of the most striking and distinct of the genus. 
Native of Sikkim-Himalaya ; summit of Tonglo, at an elevation of 
10,000 feet. Flowers ——— ?
