Slender succulent annual herb us. forming matted patches; stems much and often ± umbellately branched, branches creeping and rooting at nodes or ascending, ± flattened with membr. wings, glab. or with sparse flattened jointed hairs. Lvs sessile and subsheathing at base, 2.5-4-6 × 1-3 mm., oblong- to ovate-cuneate, upper 1/5-⅓ digitately divided into 3-5-(7) subacute to acute linear segs 0·5-2 mm. long, middle seg. us. > lateral segs, membr. when dry, glab. or sparsely white-hairy, rarely with 1-2 setae at tips of segs. Fls us. borne singly, subsessile or on pedicels up to 10 mm. long. Calyx 3-4-(5) mm. long, divided c. 1/2 way; lobes lanceolate-triangular, acute, glab. or occ. setose at tips. Corolla white, (6)-10-13 mm. long; tube slender, up to 9 mm. long, much > calyx; lobes of lower lip up to 2 mm. wide, entire. Anthers yellow to golden brown, glab. or with a few marginal hairs, awns small, almost equal. Capsule < calyx, densely setose at apex; seeds 2 per locule, c. 1·5 mm. long.
