Shrubs, 20–35 dm, ?sometimes clonal?. Stems: twigs: new growth usually appressed-pubescent, 1-year old usually dull yellowish to greenish brown or gray-brown to light or dark tan; thorns on twigs ?variable?, straight to slightly recurved, 1-year old shiny, dark mahogany or black, ± slender to ± stout, 3–6 cm. Leaves: petiole length 50% blade, ?usually narrowly winged distally?, pubescent, glandular young, often persisting; blade ?yellow or purplish in very dry spots (fall)?, ± rhombic to rhombic-ovate, rhombic-obovate, or ovate to broadly elliptic, ?on extension shoots similar, larger?, 2–5(–7.5) cm, thin to chartaceous, base ± cuneate, sometimes rounded to broadly ovate (at early anthesis not strikingly flabellate), lobes 2–4(–6) per side, sinuses moderately deep, lobe apex acute to subacute, margins serrate, ?teeth glands caducous, numerous, small?, veins 3–5(–7) per side, apex acute or subacute, abaxial surface glabrous, sparsely pilose-glabrescent, or villous, veins usually pubescent, adaxial appressed-scabrous, glabrescent or short-appressed-pubescent. Inflorescences 5–10-flowered, ?compact?; branches sparsely to densely villous, rarely glabrous; bracteoles ?usually hyaline?, linear, membranous, margins sessile-or short-stipitate-glandular. Flowers 15–20 mm diam.; hypanthium usually villous, sometimes glabrous; sepals triangular, 4 mm, margins glandular-serrate, ?apex subacute to obtuse, abaxially pubescent?; stamens (5–)10(or 20), anthers cream or ivory, sometimes pink; styles 3 or 4(or 5). Pomes scarlet to deep red, only darkened to burgundy if dried and shriveled (except in var. vernonensis), usually suborbicular to broadly ellipsoid or oblong, 8–10(–12) mm diam., pubescent or glabrous; sepal ?remnants present?, spreading to reflexed, ?not or rarely obscurely elevated?; pyrenes 3 or 4(or 5). 2n = 68.
