A small tree or more commonly a low shrub, described by Sargent as having numerous small stems often made prostrate in autumn by the weight of the abundant fruits; shoots slender, downy. Leaves of seven or nine leaflets, which are elliptical to narrowly obovate, 3 to 6 in. long and often doubly toothed, usually more or less downy beneath at first. Flowers numerous in pyramidal panicles up to 6 or 8 in. long and half as wide at the base; petals pale yellow, nearly equal, oblong-obovate, each narrowed to a slender claw, downy outside; stamens usually seven, their stalks hairy; calyx bell-shaped, downy, pale yellow-green; ovary hairy. Fruit subglobose, one- to three-seeded; seeds chestnut-brown, 1 in. wide.
Native of E. Texas and an attractive hardy shrub, closely akin to A. glabra, but distinct in its dwarf habit and narrower longer-pointed leaflets. Discovered before 1860; introduced 1909. There is a specimen of 32 × 11⁄2 ft in the Edinburgh Botanic Garden (1968).
