"A small evergreen tree ultimately 30 to 40 feet high, with a thick, 

 sturdy trunk, the branches forming a head as wide as the tree is high, 

 and reaching to the ground. Leaves narrowly oblong, tapering at both 

 ends, 4 to 7 inches long, 1 to 2 inches wide, smooth above, covered beneath 

 with a coat of silvery scales ; stalk one-half to 1 inch long. Flowers 

 blood red, borne in a compact hemispherical head, 4 to 5 inches through, 

 sitting close on the terminal whorl of leaves. Corolla bell shaped, 1$ to 2 

 inches across ; stamens 10 ; calyx very small ; flower stalk downy. 



" Native of the outer Himalayas, where it is widely spread ; intro- 

 duced in 1817. This species is one of the most variable of all rhodo- 

 dendrons, but the form just described, with crimson flowers and silvery 

 undersurface of the leaves, may be taken as the type." (W. J. Bean, 

 Trees and Shrubs Hardy in the British Isles, vol. 2, p. S//2.)

"A tree met with in the temperate Himalayas from Kumaon to Bhutan, 

 at altitudes between 8,000 and 12,000 feet. The wood is pinkish red in 

 color and shining and of slow growth. It weighs about 39 pounds to the 

 cubic foot." (Watt, Dictionary of the Economic Products of India.) 



"An evergreen shrub or small tree, the bark peeling from the branches 

 and leaving them blue-gray and smooth ; winter buds viscid ; branches 

 yellowish, sometimes smooth, sometimes bristly. Leaves in a terminal 

 cluster, oblong, heart shaped at the base, terminated by a short, fine 

 point, 4 to 9 inches long, 1 to 3 inches wide, dark dull green and smooth 

 above, pale and usually smooth beneath; stalk one-half to 1 inch long, 

 conspicuously bristly on the upper side and at the base of the midrib. 

 Flowers densely packed in a hemispherical truss about 4 inches wide, 

 blood red. Corolla bell shaped, 1$ inches across, five lobed ; stamens 

 10 ; calyx with five smooth, ovate lobes, one-fourth inch long. 



" Native of the Himalayas up to 12,000 feet, introduced about 1849. 

 This rhododendron is hardy in a sheltered spot at Kew. where it flowers 

 in April. It is somewhat gaunt of habit, but worth growing for its 

 marvelous richness of color. It is, of course, much finer in Cornwall 

 and similar places. There is some variation in the bristliness of the 

 stems and leaves. In one form the young wood is furnished with bristles, 

 and the leafstalk is bristly all round ; bristles up to one-half inch long."

Rhododendron. 



"This rhododendron is a native of the Nepal and Sikkim Himalayas 



at elevations of 9,000 to 12,000 feet. It usually grows on the limbs of 



lofty trees, where its branches hang down and are several feet in length. 



In looser forests, where light and air are better distributed, it is found
