    Sepals 2, unequal, the larger slightly enfolding the margins of the smaller, connate into a tube below, which is adnate to the base of the capsule.
    Corolla
    Petals 4–5 (6), fugacious, free or ± united, marcescent and enfolding the ripe capsule.
    Stamens
    Stamens 4 — c. 100, inserted on the corolla or at its base.
    Pistil

    Succulent annual or perennial herbs or infrequently shrublets; stems articulated or not; roots sometimes tuberous
    Leaves

    Inflorescences
    Inflorescence terminal though sometimes overtopped by subsequent growth; peduncle expanded into a flat platform bearing one or more sessile flowers and bordered by a circlet of involucral leaves, or inflorescence rarely an open cyme (1 species in East Africa); involucral bracts enclosing woolly hairs and sometimes triangular scales; flowers fugacious, developing in succession
    Calyx
    Sepals ovate-triangular, basally connate, hooded
    Corolla
    Petals 4–5(–6), adnate basally to the sepals, varying slightly in width
    Stamens
    Stamens several to numerous, adherent to the petals in a single whorl, filaments connate basally
    Pistil
    Ovary semi-inferior, multi-ovulate; style usually elongate and disarticulating at maturity; stigma branched, the branches recurving
    Fruits
    Capsule circumscissile, basal portion rim-like to infundibuliform, membranous to coriaceous, persistent, the dome-shaped top usually cartilaginous, brittle, forming a lid carrying the persistent collapsed perianth
