    Acaulous or short-stemmed annual or perennial herbs (rarely taller shrubs).
    Leaves in basal or apical rosettes.
    Flowers single, in dense cylindrical spikes from the rosettes, spikes sessile, unbranched or with branches from base of the terminal spike; peduncles with scattered to imbricate scale-like sterile bracts; fertile bracts imbricate, spirally arranged, scale-like, persistent, without or with indistinct midrib; bracteoles 2, narrowly ovate-elliptic.
    Calyx divided almost to the base into 5 sepals; dorsal much wider than the rest, the two lateral slightly wider than the two ventral which are united higher up than the rest.
    Corolla weakly 2-lipped, sometimes cleistogamous; tube linear, cylindric, widened into a short throat; lower lip 3-lobed, lobes often bifid.
    Stamens 2 (rarely 4 or 2 plus 2 staminodes), included in the throat; filaments short; anthers 2-thecous, thecae at same height, oblong or broadly elliptic, without basal appendages, connective produced apically.
    Ovary 2-locular, with 6–10 ovules per locule; stigma oblong-spathulate or rounded, entire or 2-lobed.
    Capsule 10–20-seeded, ellipsoid, sessile, rostrate (sterile from apex) with recurved apical part when ripe, retinaculae absent.
    Seed minute, ovoid-ellipsoid, often with ± truncate ends, rugose and pitted.
    Range: A pantropical genus of approximately 25 species. Range: Mostly in America, but with 5–10 species in Africa, Madagascar and SE Asia.
