Plants annual, biennial, or perennial, often matted; taproot slender. Stems prostrate to erect, branched, 5-70 cm, mostly retrorsely to spreading-pubescent on 1 side or throughout. Leaves: stipules lanceolate, 2-6 mm, apex acuminate, entire; blade oblong to elliptic or oblanceolate, 3-25 × 1-6 mm, herbaceous, apex acute and briefly cuspidate, glabrous. Cymes terminal, 20-40+-flowered, diffuse, lax, repeatedly forked or dichotomous. Flowers 5-merous, ± short-cylindric, with enlarged hypanthium and calyx cylindric, 1-1.7 mm, glabrous to pubescent with short hairs, often minutely ciliate, sometimes glaucous; sepals greenish or greenish white to brownish, veins absent, ovate to oblong, 0.8-1.3 mm, herbaceous, margins white, 0.05-0.1 mm wide, scarious to papery, apex terminated by minute cusp, hood narrowly rounded, cusp light green to whitish, straight, short-conic, 0.1-0.15 mm, minutely scabrous; staminodes subulate, 0.2-0.3 mm; style 1, cleft in distal 4/ 5+, 0.2-0.4 mm.

Chaudhri used duration and pubescence to recognize two subspecies of Paronychia baldwinii, characters that L. H. Shinners (1962c) found to vary independently in this species.
