    Habit
    Annual or perennial herbs, subshrubs or shrubs.
    Leaves
    Leaves in whorls of 4 (very rarely opposite), one pair smaller than the other, sessile or subsessile, margin revolute, apex often with a pungent mucro.
    Flowers
    Flowers in spiciform cymes with numerous flowers, each subtended by a single bract (Subgen. Acanthodium) or spike reduced to a single terminal flower (Subgen. Blepharis); cyme then solitary or several together in axils of ordinary leaves each supported by (3–)4(–5) pairs of decussate bracts (Sect. Blepharis) or clustered in heads surrounded by floral leaves differing in shape and texture from ordinary leaves and with varying numbers of irregularly arranged bracts (Sect. Scorpioideae); bracts coriaceous, usually toothed (inner glumaceous in Sect. Scorpioideae); bracteoles 2 or absent, usually linear to lanceolate.
    Calyx
    Calyx divided to base into 4 glumaceous sepals, included in bracts or ± exserted, basal 1–2 mm thickened and horny; dorsal sepal longer than the others, 3(–5)-veined and 1–3-toothed apically, ± lateral teeth; ventral sepal 2(–5)-veined, bifid (rarely entire); lateral sepals lanceolate to ovate, 1-veined.
    Corolla
    Corolla with tube narrow basally, constricted below the expanded thickened and spongy upper 1–3 mm, 1–2 mm below insertion with band of upwardly directed hairs; limb horizontal, split dorsally to give a 3–5-lobed lower lip, with a yellow thickened and spongy central callus which often terminates in 1–3 apical flanges, below puberulous to sericeous, above puberulous from sharply bent hairs (through 90°).
    Stamens
    Stamens 4, usually exserted (but hidden under dorsal sepal), inserted just inside tube on top of a thickened rim, two posterior held above anterior; filaments bony, posterior pair linear, curved, with knee at base, anterior pair slightly shorter, straight, broad and flattened, bifurcate at top into a short branch bearing the anther and an acute to obtuse ventral tooth-like appendage; anthers 1-thecous, elliptic to oblong, anterior pair slightly larger, fertile locule usually only 1/2–2/3 of total length (whole length in Subgen. Acanthodium), densely bearded and with large apical tufts of long hairs, usually glandular.
    Ovary
    Ovary glabrous, 2-locular with 2 ovules per locule; disk large, annular; style usually glabrous, with two tufts of short glandular hairs at base; stigma subentire or with two distinct lanceolate subacute lobes.
    Fruits
    Capsule 2(–4)-seeded, ovoid-ellipsoid, sessile, glossy, flattened dorsi-ventrally, central wall thick and woody.
    Seeds
    Seed discoid, covered with long white branched hygroscopic hairs.
    Distribution
    Range: A genus of 129 species in the Old World tropics and subtropics. Range: Especially numerous in eastern and southern Africa.
