    Amaranthaceae, C.C. Townsend. Flora of Tropical East Africa. 1985

    Habit
    Annual herb, usually considerably branched (the branches divaricate-ascending) but simple in poorly developed specimens, 0.2–0.9 m.; stem and branches ridged, often reddish, moderately to rather densely pilose with upwardly directed ± appressed hairs.
    Leaves
    Leaves broadly obovate to linear, 1.5–8.5 × 0.2–3.5 cm., thinly to moderately pilose, sessile and in the broader-leaved forms commonly constricted ± 1/3 of the way up and then expanded to an auriculate base, apex blunt to subacute, obscurely mucronate.
    Inflorescences
    Inflorescence green or the tips of bracts, bracteoles and tepals frequently pink to carmine, conical when young but finally subglobose to cylindrical, 1.2–6.5 × 1.2–1.4 cm., very dense, on a short to long (up to 11 cm.) peduncle or more rarely sessile through branch-condensation and then often with short lateral inflorescences at the base; axis villous.
    Bracts
    Bracts ovate-lanceolate, 3–5 mm. white-membranous, sparingly pilose along the central dorsal surface or glabrous, gradually tapering to the acute 1–1.5 mm. arista formed by the excurrent midrib.
    Bracteoles
    Bracteoles narrower, lanceolate, 2.75–5 mm., more densely pilose, the arista 1.75–2.5 mm.
    Flowers
    Flowers truncate at the base, where they are indurate, fused to the bracteoles and attached to the inflorescence-axis by a knob-like stalk.
    Tepal
    Tepals lanceolate-subulate, greenish centrally, firm and opaque except for the narrowly hyaline margin, the stout midrib excurrent in a very sharp pale to reddish, 1–2 mm. arista, erect or divergent at the tips; 2 outer 5.5–7 mm., ± densely furnished with upwardly directed ± spreading white hairs, with 5 nerves which are often white and obvious near the base but obscured above; 2 inner ± 1 mm. shorter, narrower, 3-nerved, hairs mostly confined to the central and upper parts; middle tepal intermediate.
    Perianth
    Perianth and bracteoles falling in one unit in fruit.
    Stamens
    Stamens 2–3 mm.; pseudostaminodes ± 0.75–1 mm., oblong, truncate with an incurved lobule at the apex, dorsal scale filiform to considerably fimbriate.
    Ovary
    Ovary roundish, ± 1 mm., with a firm, transversely ridged apex.
    Style
    Style slender, 1–1.5 mm.
    Fruits
    Capsule oblong-ovoid, 2–2.25 mm., the firm flat apex with a transverse crest on each side of the style.
    Seeds
    Seed oblong-ellipsoid, ± 2 mm., brown, shining.
    Figures
    Fig. 27.
    Habitat
    Sides of roads and tracks in light shade, dry open woodland, light scrub, rock crevices, usually on sandy soil; 240–1620 m.
