Branohlets, petioles, and under side of leaves covered with short soft 

 pubescence. Leaves elliptic or obovate, entire, obtuse, on long petioles, 

 often longer than leaves, lateral nerves 10-15 pair, parallel, straight below, 

 arcuate above. Flowers on slender pedicels, in a lax panicle, ramifications 

 and pedicels pilose, bracts subulate. Fertile fiowers few. Drupe com- 

 pressed, semicordate or obliquely obovate, 1 -seeded, about \ in. long, 

 covered with short white hairs while young, glabrous and rugose with 

 prominent veins when ripe. Pedicels of the sterile flowers elongated 

 after flowering, and densely covered with long silky hairs, forming a 

 spreading panicle of slender feathery branches. 



Eastern slopes of Suliman range and N.W. Himalaya to the Sarda river, 

 between 2300 and 6000 ft. Outside India in South Europe, West Asia, Cau- 

 casus. A shrub or small tree, to 20 ft. high, and 3 ft. girth, growing some- 

 what gregarious, mostly on arid, sunny slopes, often forming an underwood in 

 forests of Pinus longifolia with Berheris, Andromeda, and other shrtibs. Leaf- 

 less for a short time, the young reddish leaves come out in April. El. Apr.- 

 Sept. ; fr. autumn. The South European shrub is hardy in England. 



i3ark of trunk and larger branches dark grey or brown, with white dots, and 

 often with horizontal yellowish bands, smooth, hard, peeling off in flakes. The 

 leaves and flowers when bruised emit a pleasant balsamic odour, supposed to 

 resemble the smell of Mangoes, hence one of the vern. names. Wood yellowish, 

 hard, strong, close- and even-grained, often beautifully mottled, used for inlaid 

 and cabinet work in South Europe. In the Himalaya the twigs are used for 

 basket-work, and the small branches as tooth-sticks. Bark and leaves used for 

 tanning. 



* I have seen a good deal of R. GoUnus in South Europe, and of R. velutina in tli«, 

 Himalaya, and do not hesitate to unite them, though the former is glabrous. '5;
