Sissoo, Roxbg. A good-sized tree, 80 ft. high in India: leaves pinnate; leaflets 5, alternate, stalked, obovate, abruptly acuminate, pubescent beneath: flowers white, in short, axillary panicles. - In India considered one of the best timbers, whenever elasticity and durability are required. Intro, at Santa Barbara, where it is hardy but growth said to be very slow. The Sissoo tree is worth trial in nearly frostless districts, especially along sandy river banks. It improves sterile lands. Experiments in Egypt have shown its most remarkable property of standing severe droughts, as well as submersion for a long period. The wood is very elastic, seasons well, does not warp or split, is easily worked, and takes a fine polish. It is also a durable wood for boats. The tree is raised easily from seeds or cuttings, and is of quick growth. Other species of Dalbergia are of economic value and have been sparingly planted.
