Description

General: annual or more often perennial. Stems usually numerous, 10-60 cm long, trailing or creeping, sparsely spreading-stiff-hairy, from a taproot. Small plants rarely single-stemmed and erect.

Leaves: opposite, coarsely flat-stiff-hairy, mostly with winged stalks, the blade commonly 2-5 cm long and 1-2.5 cm wide, irregularly toothed and cleft, often with one or two pairs of pinnate segments near the base, well differentiated from the larger, terminal segment.

Flowers: many in dense, elongated clusters up to 15 cm long, at the end of the main stem and branches. The leaf-like bracts entire, lance-linear, spreading, 5-15 mm long, conspicuously surpassing the 2.5-4 mm calyx of the flowers. Corolla inconspicuous, almost hidden by the bracts, bluish or pinkish to rarely white, the tube about 4 mm long, the limb 2-3 mm wide, unequally 5-lobed. May-September.

Fruits: small, dry, mostly enclosed in the calyx, readily separating into 4 linear-oblong nutlets.
