To the northward in its range it inhabits usually well-drained gravelly or sandy soil, in company with the Post, Black-jack, Chin- quapin and other Oaks, Mocker-nut and Shag- bark Hickories, Blue Ash, Red-bud, etc., but in the south it occupies moist low-lands, as well as the drier uplands. A gum exudes from it when wounded which gives it the name Gum- elastic. It is a clear viscid substance, some- times used domestically. Its wood is rather liard and heavy, a cubic foot weighing when dry lbs., tough, smooth-grained and of marked charac- teristic Leaves mostly obovate or oblanceolate. 1-21/2 in. long, narrow, cuneate at base, rounded or bluntly pointed at apex, woolly tomentose at first but at maturity dark green and glabrous above and densely tomentose beneath as are the sliort petiole's and all new growth, tardily deciduous. Flotocrs (,Tuly-Aiigust) in usually several-flowered fascicles with pedicels about Vs in. long; calyx with obtuse or rounded lobes; staminodia ovate, acute denticulate. Fruit drupe, black, Ms in- or less in length ; seed oblong, rounded at apex, about ^4 in. Var. riqida. Gray, is a form found along the Mexican boundary with rigid spinescent branchlets and smaller thicker leaves. 1. A. W., XI, 260. 2.
