Shrubs, 5–10(–15) dm, armed. Stems annual, arching to mounding, glabrous, eglandular, not pruinose; prickles sparse, slightly hooked, stout, 3–4 mm, broad-based. Leaves deciduous, pinnately compound; stipules lanceolate to oblanceolate, 8–13 mm; leaflets (3–)5–7, terminal lanceolate to narrowly ovate, (5.5–)6.2–8.5(–9.7) × (1.8–)2.2–3(–4.2) cm, base usually rounded, sometimes truncate to subcordate, unlobed, margins finely to coarsely doubly serrate, apex acuminate, abaxial surfaces with prickles on midvein, glabrous, eglandular. Inflorescences solitary flowers or 2–3-flowered clusters. Pedicels: prickles sparse, slightly hooked, glabrous, eglandular. Flowers bisexual; petals white, broadly obovate to suborbiculate, 12–15(–18) mm; filaments laminar; ovaries glabrous, styles glabrous. Fruits red, oblong, 1.4–2 cm; drupelets 50–100, strongly coherent, separating from torus. 2n = 14.
