    Habit
    Erect perennial herbs or low shrubs.
    Leaves
    Leaves entire, opposite on mostly branched stems.
    Flowers
    Flowers in pedunculate (rarely some sessile) spike-like bracteate thyrses, each bract subtending a bibracteolate partial inflorescence. The sterile flowers (which develop so rapidly as to be difficult to detect in young flowers) consist of a single finally hard and gibbous-based spine, the entire partial inflorescence thus falling as a 3-spined burr complete with bracteoles; bracts persistent on the inflorescence axis.
    Inflorescences
    Partial inflorescences normally consisting of two (occasionally one in the upper part of the thyrse) fertile flowers; one of these is subtended dorsally by a single sterile flower (which is thus contained in a partial inflorescence bracteole), the other by a sterile flower on each side, each of which is contained in a bracteole of its own.
    Perianth
    Perianth segments 5, obviously narrower from the outer to the inner.
    Androecium
    Stamens 5; filaments filiform, flattened, fused only at the extreme base without intermediate pseudostaminodes; anthers narrow, bilocular.
    Pistil
    Ovary uniovulate, somewhat compressed, delicate; style slender, with two short or elongate stigmatal branches.
    Fruits
    Utricle scarcely compressed, delicate save for a small, firm area about the base of the style, irregularly ruptured by the developing seed; seed with abundant endosperm.
