Heads globose, pseudoterminal and axillary; peduncles longer than the leaves; pedicels slender, the upper ones 4-5 mm, up to twice as long as the calyx-tube, deflexed after anthesis. Calyx-tube 1-1-5 mm, with 5 veins distinct, the other 5 often obscure; calyx-teeth 2-3 mm, longer than the tube, the two upper slightly longer than the others, subulate, separated by broad obtusesinuses; corolla (5—)7—10 mm, purple or white at first, pink later, becoming brown.
