    Portulacaceae, H. Wild. Flora Zambesiaca 1:2. 1961

    Annual, biennial or perennial herbs; branches erect or often prostrate.
    Leaves shortly petiolate or sessile, opposite or alternate, fleshy, cylindric or plane, glabrous (at least in our species); stipules divided into numerous hairs or more rarely membranous or absent.
    Flowers sessile, solitary or a few together at the ends of the branches and surrounded by a group of 2-several apical leaves.
    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.
    Petals 4–5 (6), fugacious, free or ± united, marcescent and enfolding the ripe capsule.
    Stamens 4 — c. 100, inserted on the corolla or at its base.
    Ovary semi-inferior, 1-locular, at least in the upper part; placentation free central; ovules many or very rarely 1 or several; style simple with 2-several stigmas.
    Capsule dehiscing transversely.
    Seeds 1-?, usually reniform, smooth or variously tuberculate or granulate.

    Portulacaceae, Sylvia M. Phillips. Flora of Tropical East Africa. 2002

    Succulent annual or perennial herbs or infrequently shrublets; stems articulated or not; roots sometimes tuberous
    Leaves alternate or opposite, fleshy, linear to obovate, shortly petiolate, caducous, often absent at flowering time; axillary hairs and scales present, these sometimes conspicuously encircling the nodes and overlapping the leaves
    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
    Sepals ovate-triangular, basally connate, hooded
    Petals 4–5(–6), adnate basally to the sepals, varying slightly in width
    Stamens several to numerous, adherent to the petals in a single whorl, filaments connate basally
    Ovary semi-inferior, multi-ovulate; style usually elongate and disarticulating at maturity; stigma branched, the branches recurving
    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
    Seeds many, grey, brown or black (immature seeds brown), sometimes iridescent with a metallic sheen, reniform to rounded, smooth or often ornamented with tubercles or pegs.
