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

Morphology General Habit
Annual, everywhere glabrous herb with slender root.
Morphology Stem
Stems up to 22·5 cm. long, ± 1 mm. in diam., soft, distinctly 4-winged (at least when dried), whitish to pale green, the wings hyaline, simple or branched sometimes from the base (the branches ascending or erect, shorter than the main stem), leafy nearly from the base to the apex or leafless below; internodes usually longer than the leaves, the lower and median ones up to 14 mm. long.
Morphology Leaves
Leaves 5-8·5 mm. long, linear or linear-lanceolate, usually with nearly the same breadth from base to apex, the cauline and rameal ones blunt or truncate at the apex which is provided with ± numerous short papillae, entire, sessile and connate at the base into a sheath up to 0·5 mm. long, not spurred below their insertion with the stem; axillary-fascicles distinctly shorter than the subtending leaf.
Morphology Reproductive morphology Flowers
Flowers (4)5-merous in 2-7-flowered axillary fascicles nearly along all the stem and branches or sometimes flowers solitary; pedicels up to 3·5 mm. long, very unequal in length in each fascicle, filamentose.
Morphology Reproductive morphology Flowers Calyx
Calyx 1-2 mm. long, ± longer than the corolla, pale green or whitish; sepals oblong-lanceolate, attenuate-subulate to the apex which is acute or nearly so, very thin, stellate.
Morphology Reproductive morphology Flowers Corolla
Corolla 0·6-1 mm. long, white or pale pink, thinly membranous, hyaline to brownish on drying; petals ovate-lanceolate or ovate, folded above the middle and thus attenuate and cuspidate, nearly free, stellate.
Morphology Reproductive morphology Flowers Androecium Stamens
Filaments ± attaining the middle of the corolla; anthers c. 0·15 mm., subcircular, yellow.
Morphology Reproductive morphology Fruits
Follicles ± 0·75 mm., obliquely obovoid, contracted into the very short styles, pale green, nearly translucent, 2-seeded.
Morphology Reproductive morphology Seeds
Seeds c. 0·5 x 0·22 mm., oblong, obtuse at base and apex, shallowly longitudinally ridged, the ridges straight, not shining.
Morphology General Scales
Scales minute, narrowly spathulate.
