Chromosome number: 2n = 54 (Stebbins and Pun 1953; Fedorov 1969).

Description and morphology: Small, annual, ephemeral plant (height up to 20 cm). Stem: glabrous, ramified from base; with milky juice. Leaves: linear or oblong, fine nerved (5– 15 cm long, 4–7 mm wide); lower – petiolate; middle – sessile, glabrous or slightly pubescent. Flowers: bisexual; small, yellow, pentamerous, assembled in axillary or solitary capitules (5–8 mm long). Grows in early spring.

Reproduction: Entomophilous plant. Flower and fruit maturation: end of April. Cycle ends in May. Fruit: achene (8–16 mm long), curved, membranous, inflated trilocular (up to 1 cm long), opening by valves, linear-cylindrical, crescent intra-curved. Mature achenes covered with dense short spines.

Pastoral importance: Insignificant in terms of biomass contribution, but good value with other ephemerals and ephemeroids as green material before fruit ripening. Fodder value: At flowering contains (% DM): ash 13.0–14.4; crude protein 13.8–15.3; fat 3.6–3.9; cellulose 22–25; nitrogen-free extract 37–41.

Habitat: Occurs in patches or as single plants with other ephemerals in semi-desert and deserts on clay, loamy and clay-gravelly soils and alluvial deposits.
