Shrub, dense, mounded, 2–5(6) dm. Stem: many from generally short, stout trunk, spreading to ascending, round in ×-section, densely puberulent, terminating in thorns, these often appearing forked at ends of major branches. Leaf: alternate (leaf-like bracts appearing clustered on short flower shoots), sessile, (2)4–10(16) mm, linear-oblanceolate to oblanceolate, 3-cleft to middle, densely puberulent, generally only present at flower. Inflorescence: axillary, compact cluster. Flower: calyx puberulent, lobes (4)5–6(8), (1.8)2–4(5) mm, linear; corolla white tinged red or purple, red in bud, lobes 4–5(6), obovate.

Seed: generally 2; (5)5.7–7.2(8) mm, elliptic to obovate in outline, planoconvex to lenticular in ×-section, seed coat appearing smooth, shiny. [Online Interchange]
Flower: unisexual or bisexual, calyx tube in flower generally < 1.4 mm; filaments < 1 mm, anthers generally appearing sessile; bisexual flowers in showier, denser inflorescence, flowers larger.
