Amaranthaceae, C. C. Townsend. Flora Zambesiaca 9:1. 1988
- Habit
- Annual herb, simple in very reduced plants, occasionally branched from the base with decumbent branches, but usually erect with many long, slender, erect branches, (0.25) 0.45–1.2 (2) m. tall; stems frequently red, terete below, more or less quadrangular above striate, clad (as are the branches) with an indumentum of more or less dense, upwardly directed to subpatent whitish hairs.
- Leaves
- Leaves lanceolate-oblong to oblong-elliptic, those of the main stems 2–10 × 0.9–3 cm., more or less abruptly contracted at the base (superior leaves sessile, the lower usually very shortly petiolate), obtuse-apiculate to subacute at the apex, thinly to moderately furnished with upwardly-directed or subpatent hairs, the upper surface usually darker.
- Inflorescences
- Inflorescences subglobose to cylindrical, (1) 1.5–3.5 (5) × (1.25) 1.5–1.75 cm., the flowers very dense and concealing the white-pilose axis, sessile above 2–4 lanceolate to ovate, short leaves; commonly in groups of 3 (a terminal with two laterals on widely spreading branches).
- Bracts
- Bracts ovate-acuminate, c. 5–8 mm. long, membranous with a narrow or wider greenish central band, very shortly pilose along the midrib only to more generally long-pilose, the midrib excurrent in a distinct, sharp arista.
- Bracteoles
- Bracteoles lanceolate-ovate, 6–9 mm. long, densely long-pilose at least along the midrib dorsally, the midrib excurrent in a sharp mucro, the apex of one bracteole (and not rarely the entire flower) more or less curved.
- Tepal
- Tepals narrowly lanceolate, the outer 2 densely appressed-pilose, narrowly pale- margined with a firm green centre, 6–8.25 mm.; inner 2 c. 0.5–1 mm. shorter, less pilose, 3 nerves sometimes visible in transmitted light only; middle tepal intermediate; all with a rigid, spine-like apex.
- Stamens
- Stamens 2.5–5 mm. long, the filaments floccose-hairy near the base; pseudostaminodes flabellate, 0.75–1 mm. long, the margins more or less floccose, dorsal scale absent in all material examined.
- Pistil
- Ovary quadrate-obpyriform, slightly compressed, with a faint apical keel; style slender, (1) 2.5–3.25 mm. long.
- Fruits
- Capsule turbinate (“drum-shaped”), c. 2.5 mm. long, with a broad, flat, firm apex; seeds oblong-ovoid, 2–2.25 mm. long, brown, shining, faintly reticulate.
