There are usually three principal heads in an inflorescence on axes 0.7-2.5 cm long.

Two main foliose or subfoliose bracts are located at the summit of the peduncle and subtend the three main axes of the inflorescence. Each of the three heads is sub-hemispheric with 15-20 flowers. Each of these heads is surrounded by two large connate bracts united at their base. The outer flowers of a head are subtended by individual bracts, whereas the inner flowers are not subtended.
