A tree about 30 feet high, (sometimes 60 — 80. Mich.) Leaves une- 
qually pinnate, with 4 — 7 pair of leaflets, leaflets frequently alternate, 
oval, emarginate, pubescent. Racemes axillary, simple. Calyx pubescent, 
spotted, 4 cleft, the upper segment broad, emarginate, the three lower 
acute. Corolla white, vexillum large with the sides reflected. Legume 
smooth. 
This tree which is frequently cultivated for ornament on account of the 
beauty and fragrance of its flowers, is also much valued for the quality 
of its wood. It is supposed to make the most durable posts, when ex- 
posed to the weather, of any tree in this country, and is also preferred to 
any other wood for the trunnels of vessels. 
Grows in the mountains in rich fertile soils. Not found in its native 
State on the sea coast of Carolina. 
Flowers March and April.
