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

    Habit
    A succulent, 8-90 cm. high perennial, forming clumps up to about 90 cm. in diameter.
    Stem
    Stem arising from a fleshy to woody obconical or swollen tuber, erect, straight, usually simple, ± stout (up to 10 mm. in diameter at the base) or sometimes ± slender, terete, pale- or yellow-green below, bright red to reddish-brown above, usually crimson on drying, glabrous towards the base, papillose-hairy or shortly papillose upwards below the nodes along two ± short stripes alternating with the lamina of the leaves (the papillae usually very short, patent, obtuse or, if long, then hair-like), or completely glabrous, rarely papillose throughout.
    Leaves
    Leaves 2·5-26·5 x (0·1-0·2) 0·4-2·7(3·3) cm., sometimes up to 37 times longer than wide, the basal ones the longest and rosulate, oblong- to linear-lanceolate or linear, ± attenuate, the lower cauline leaves similar to the basal ones but shorter, the succeeding ones lanceolate or linear to oblong- or ovate-lanceolate, the uppermost sometimes bract-like, all acute or subacute at the apex, entire and with a row of short, contiguous, obtuse, white papillose cilia at the margin, sessile, ± long-connate at the base, clasping the stem below, then subappressed to it, finally erect or somewhat arched, flat, fleshy (but not very thick), pale to bright green when fresh, greenish-brown or dark brown when dry, usually glabrous on both faces or very rarely papillose-hairy beneath or on both surfaces; sheath (0·5)1-3 cm. long in the lower cauline leaves, shortening in the following; all internodes shorter than the leaves (sometimes the stem completely concealed by the sheaths and the clasping part of the laminas) or the upper ones subequalling or longer than them.
    Flowers
    Flowers 5-merous in a repeatedly dichotomous, usually very dense, subhemispherical, corymbose inflorescence, 1·5-22(30) cm. in diam.; branches ± papillose to nearly glabrous; pedicels 2-6 mm. long, glabrous or sparsely papillose.
    Calyx
    Calyx (1)1·5-3(4) mm. long, 1/3-1/2 (2/3) as long as corolla, rarely subequalling it, pale green; sepals ovate-lanceolate or ovate-elliptic to linear-lanceolate, not or ± attenuate, acute, with one terminal ± long obtuse papilla at the apex, usually entire and without marginal papillae or sometimes obtuse papillae present over a short to ±: long extent of the margin as well as on the median nerve above.
    Corolla
    Corolla (2·25)2·5-3·5(4·5) mm. long, white, pinkish-white or cream-white, sometimes red-tipped, or yellow, rarely red; petals 0·75-1·5(2) mm. wide, elliptic-oblong to ovate-oblong or ovate, obtuse or nearly so, slightly thickened at the top, not or indistinctly mucronate below the apex, smooth.
    Stamens
    Filaments 1·5-2 mm. long; anthers (0·25)0·3-0·4(0·5) mm., subcircular.
    Fruits
    Follicles (incl. styles) 2-2·5(2·75) mm. long, contracted into the very short styles.
    Seeds
    Seeds c. 0·5 mm. long, oblong.

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

    Habit
    A succulent rosette-forming perennial forming clumps up to ± 90 cm. in diameter (fide F.Z.).
    Roots
    Rootstock a fleshy to woody obconical or swollen, sometimes bifurcating tuber with remains of former leaves.
    Stem
    Stems annual, dying back after flowering, erect, usually simple, up to 90 cm. high, usually ± 30 cm., terete, ± stout, up to 10 mm. in diameter at the base, ± glabrous or minutely papillose-pubescent near the base, becoming increasingly papillose upwards, the papillae in broad vertical bands between the nodes alternating with the laminae.
    Leaves
    Leaves sessile, oblong- to linear-lanceolate or linear, (1–)2.5–17.5(–35) cm. long, (0.1–)0.2–2.1(–3.5) cm. wide, apex obtuse to subacute, bases of opposite leaves united to form a sheath around the stem (0.5–)1–2.5(–3) cm. high, basal leaves sometimes long-attenuate at the base, margins entire, shortly white papillose-ciliate, otherwise glabrous; cauline leaves, sheaths and internodes shortening towards the apex.
    Inflorescences
    Inflorescence a terminal, repeatedly dichotomous, usually rather dense, subhemispherical, corymbose cyme, with foliaceous bracts; branches ± papillose to subglabrous; pedicels 2–6 mm. long, glabrous or sparsely papillose.
    Flowers
    Flowers 5-merous.
    Calyx
    Calyx-lobes narrowly to broadly triangular to ovate-lanceolate, (1–)1.5–2.5(–3.5) mm. long, 0.6–0.8 mm. wide, subacute with a terminal obtuse papilla, united at the base for 0.5 mm., margins entire, rarely with a few vestigial papillae.
    Corolla
    Petals yellow (not in E. Africa), cream, white or pink, elliptic-oblong to oblong-ovate, oblong or ovate, (2.5–)3–4(–4.5) mm. long, (0.75–)1–1.3(–2.3) mm. wide, obtuse, slightly thickened; base united for ± 0.5–1 mm., entire, glabrous.
    Stamens
    Stamen-filaments 1.5–2 mm. long; anthers suborbicular, (0.2–)0.3–0.5 mm. long, yellow.
    Nectaries
    Nectary scales transversely oblong to almost square, 0.2–0.6 mm. high, 0.4–0.8 mm. wide, truncate or emarginate.
    Carpels
    Carpels oblong, up to 2.7 mm. long, rather abruptly contracted into short styles, indistinctly papillose-ciliate along the suture.
    Seeds
    Seeds 2–6(–8) per carpel, broadly oblong, ± 0.5 mm. long, ± 0.3 mm. wide, minutely longitudinally rugulose (indistinguishable from those of C. alba).
    Figures
