General: Annual herb from a taproot, short, straight, appressed-hairy (and sometimes curly- or spreading-hairy) throughout; stems usually branched, 10-80 cm tall.
Leaves: Basal leaves oblanceolate, to 10 cm long, often deciduous; stem leaves linear to narrowly oblong or oblanceolate, reduced upwards to the leafy, lanceolate bracts of the inflorescence, unstalked, entire, alternate.
Flowers: Inflorescence of narrow, elongating clusters with bracts throughout; flower stalks ascending to erect when in fruit; petals blue (sometimes white), fused at base into a small tube that flares (2-4 mm wide) at top to 5 lobes, with 5 yellow bulges at throat; fruiting calyces 2.5-3 mm long, the lobes spreading
Fruits: Nutlets 4, clustered together, egg-shaped, 3-4 mm long, with 2(-3) marginal rows of slender, barb-tipped prickles distinct to the base, those of the outer row usually shorter than those of the inner.
