20' 



The Clammy Locust is a small tree, only 

 under the most favorable conditions attaining 

 the height of 30 or 40 ft. and 10 or 12 in. in 

 diameter of trunk. Such individuals are rare 

 as it is usually not of half that size and often 

 only a large shrub, spreading, as do other 

 representatives of the genus, by underground 

 stems and forming considerable thickets. As 

 an isolated tree it has a rather open oblong 

 top with slender branches. Its branchlets and 

 all new growths are covered with a shining 

 sticky exudation and viscid hairs, by which 

 it may be readily recognized. 



Its native home is restricted to the high 

 slopes 01 the Alleghany Mountains, in the in- 

 teresting forests where only are found the 

 Rhododendron, Kalmia, Witch Hazel, Moun- 

 tain Holly, etc., in tree forms, and there it is 

 by no means common. On account of its 

 handsome foliage and flowers, however, it has 

 been widely planted for ornamental purposes 

 throughout eastern United States and Europe 

 and has become naturalized in many locali- 

 ties, as far north in this country at least as 

 the Canadian frontier. 



Its wood is similar to that of the Yellow 

 Locust, a cu. ft. when absolutely dry weighing 

 50.44 lbs., but is not of commercial import- 

 ance. 



Leaves 10-12 in. long with slender sticky 

 {ilandular-hispid petioles, ll-i!l ovato-obloni^ 

 nearly glabrous petiolulate leaflets from 1-2 in. in 

 longth, rounded at base, rounded or pointed and 

 mucronate at apex : stipules subulate and somo- 

 times delicate spines : stipels very small and 

 slender ; branchlets and all new growths glandular 

 hispid. Flou-crs (June) in rather dense oblong 

 axillary racemes, not fragrant, rose-colored, the 

 standard marked on inner face with yellow blotch. 

 Frtiit: pods. 2-Zy2 in. long, linear-lanceolate, thin 

 gladular hispid with reniform seeds about Vs in. 

 long.
