    Crassulaceae, R. Fernandes. Flora Zambesiaca 7:1. 1983

    Habit
    A perennial, creeping herb, forming dense to lax mats.
    Stem
    Stems up to 35(46) cm. long, prostrate or ascending, rooting at the lower nodes (roots very slender), simple or often the ± long prostrate part emitting short to ± long erect or ascending branches, these also rooting, mostly herbaceous-succulent (nearly translucent on drying), 4-gonous, glabrous except for two longitudinal lines of papillose hairs along two opposite sides, pale green; lower and median internodes up to 7·5 cm. long, rather longer than the leaves, the others successively shortening upwards (the uppermost shorter than the leaves).
    Leaves
    Leaves 0·5-2·8 cm. long (with the petiole) and 0·4-1·5 cm. broad, ovate-cuneate, triangular-ovate to elliptic or rhombic, rarely suborbicular, shortly acuminate, acute and sometimes apiculate at the apex, rarely (the suborbicular ones) obtuse, entire, sometimes minutely papillose-Sérrulate at the margin, cuneate or ± long attenuate into the petiole, glabrous, pale green (paler below), flat, succulent, usually thinly membranous on drying, sometimes longitudinally parallel-lineolate (the lines short, slender, brownish) and with a submarginal row of pellucid small dots; petiole ± 0·4 to ± 1·3 cm. long (delimitation from the lamina usually difficult), glabrous, dilatate below and connate with the opposite one in a sheath, provided with axillary fascicles of minute leaves or with short branchlets; sheath 0·5-1·5 mm. high, papillose-hairy at the margin.
    Flowers
    Flowers 5(6)-merous, usually solitary in the axils towards the extremities of the stem and branches, one for each node and alternating at the contiguous nodes, sometimes also in contracted terminal few-flowered inflorescences ± concealed by the upper leaves; pedicels 3-21 mm. long (the lowest ones the longest), filiform, ampliate-obconical below the calyx, usually glabrous.
    Calyx
    Calyx (2·75)4·5-5·5 mm. long, glabrous, green, usually more than half as long as but not exceeding the corolla; sepals (2·5)3·5-5 x 0·75-1(1·5) mm., lanceolate or oblong-lanceolate, attenuate towards the rather acute apex, connate at base for c. 0-5 mm., flat, with whitish-hyaline margins, sometimes brownish-lineolate along the median part.
    Corolla
    Petals (3)5-6 x 1·25-1·75 mm., oblong-lanceolate, acute, not mucronate, smooth on both faces, nearly free, usually white, rarely tinged with pink towards the apex outside.
    Stamens
    Filaments ± 3 mm. long; anthers c. 4 mm. long.
    Fruits
    Follicles (3)4-5·5 mm. long (with the styles), oblong, contracted into the styles, ± equalling the corolla-length, minutely pitted; styles ± 0·5 mm. to ± 0·75 mm. long.
    Seeds
    Seeds c. 0·5 mm. long, oblong, brownish, minutely tuberculate.

    Crassulaceae, G.E. Wickens. Flora of Tropical East Africa. 1987

    Habit
    A creeping mat-forming perennial herb.
    Stem
    Stems 4-angled, glabrous except for 2 longitudinal lines of papillose hairs along opposite sides, prostrate or ascending, up to 50 cm. or more long, sparingly branched, rooting at the lower nodes; internodes generally rather long.
    Leaves
    Leaves petiolate or subsessile, ovate-cuneate, triangular-ovate to elliptic or rhombic, rarely suborbicular-spathulate, 0.6–2(–3.2) cm. long, 0.2–1(–1.8) cm. wide, sharply acuminate, acute and usually apiculate, rarely obtuse, base cuneate or abruptly long-attenuate into the petiole, margins entire or minutely papillose-serrulate, with a submarginal row of pellucid dots, pale green, succulent; petiole barely differentiated from the lamina, petioles of opposite leaves forming a saccate sheath 0.5–1 mm. high, papillose-hairy at margins.
    Flowers
    Flowers 5(–6)-merous, usually solitary in the axils of the upper leaves, usually 1-flower per node in alternate axils, at least in the lower part of the flowering stems, apex of stem sometimes with a contracted inflorescence ± concealed by the subtending leaves; pedicels slender, 3–17(–21) mm. long, glabrous or sparingly pubescent.
    Calyx
    Calyx-lobes lanceolate or oblong-lanceolate, 3.5–5 mm. long, 0.75–1 mm. wide, acute to acuminate, connate at the base for ± 0.5 mm., margins hyaline, glabrous.
    Corolla
    Petals white or pink, oblong-lanceolate, 5–6 mm. long, 1.2–1.8 mm. wide, acute.
    Stamens
    Stamen-filaments white, ± 3 mm. long; anthers pale yellow, suborbicular, ± 0.4 mm. long.
    Nectaries
    Nectary scales inconspicuous.
    Carpels
    Carpels oblong, 4–5.5 mm. long, ± abruptly contracted into the style; style 0.5–0.7 mm. long.
    Seeds
    Seeds numerous (± 24), oblong, ± 0.5 mm. long, 0.3 mm. wide, yellow-brown, minutely tuberculate.
    Habitat
    Moist ground by streams and swamps in upland forest and bushland, cultivated land and roadsides; (1300–)2500–3500 m.
