Perennial or rarely annual herbs or shrubs. Caudex usually short, more or less woody, branched, rarely long and strongly branched with ligneous branches. Leaves usually in basal rosettes, sometimes in fascicular rosettes on the scape branches, very rarely present in numerous dense facsicles along the ligneous branches. Spikelets aggregated into spikes of varying length and compactness, terminating the branches of the inflorescence. Calyx funnel-shaped, obconical to nearly tubular, more or less scarious, straight or oblique in the lower region; limb 5-lobed; nerves thick usually terminating below the margin, very rarely excurrent. Corolla 1.5 times as long as the calyx; petals distinct, slightly connate at the base. Stamens free, adnate at the very bases to the petals. Ovary subovoid, style distinct from ovary; styles five, quite free at the base; stigmas cylindrically filiform.
