Amaranthaceae, C. C. Townsend. Flora Zambesiaca 9:1. 1988

Morphology General Habit
Erect or occasionally prostrate or ascending annual herb, with numerous stems c. 0.3–1 m. tall, much-branched in the lower half and frequently also above, the lowest internodes of particularly the lower branches very divergent.
Morphology Stem
Stem and branches striate, the lower internodes terete, the upper subquadrate and more or less sulcate, nodes somewhat swollen; indumentum very variable, from subglabrous or with sparse soft pubescence to densely pilose with a double indumentum of shorter soft hairs and long, fine, multicellular, spreading bristly hairs (even when absent elsewhere tufts of bristly hairs occur between the branches and leaves at least of the upper nodes, frequently forming an annulus there).
Morphology Leaves
Main stem and branch leaves cordate-ovate to broadly ovate or rarely cordate-lanceolate,obtuse to acuminate at the apex, 1.3–7 × 0.7–5.2 cm., the lowest on petioles up to c. 1 (1.8) cm. long, leaves towards the ends of the stem and branches reducing in size and almost sessile; indumentum of mature leaves very variable, from green on both surfaces and moderately softly appressed-pilose below and thinly so with long and shorter multicellular, strigose hairs above to moderately appressed-pilose above and densely silvery-sericeous on the lower surface (always so in young leaves).
Morphology Reproductive morphology Inflorescences
Inflorescence a large, open compound panicle, of axillary opposite panicles formed of simple or branched spikes, each with a flexuose, glabrous rhachis; peduncle and branches of the partial inflorescences capillary, glabrous or with long, strigose, multicellular hairs, the axes zigzag; bracts lanceolate, 0.75–1 mm. long, sparingly pilose, mucronate with the excurrent midrib; bracteoles similar but slightly shorter.
Morphology Reproductive morphology Flowers
Flowers sessile.
Morphology Reproductive morphology Flowers Tepal
Tepals, green, acute, prominently 3-nerved with the nerves confluent at the apex and excurrent in a minute mucro, glabrous or usually more or less furnished with spreading, white, multicellular, minutely denticulate hairs; outer 2 tepals 2–2.5 mm. long, narrowly hyaline-margined with all 3 nerves equally strong, if hairs present then all nerves white-pilose, hairs sometimes also present on the surfaces between; inner 2 widely hyaline-margined (the margin wider than the nerved central portion at halfway up the tepal), pilose only along the midrib, which is much stronger than the lateral nerves; middle tepal with one side as in the outer 2 and one as in the inner 2.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens delicate, c. 1.5–1.75 mm. long; pseudostaminodes none.
Morphology Reproductive morphology Flowers Gynoecium Style
Style short, c. 0.5 mm. long.
Morphology Reproductive morphology Fruits
Capsule ovoid, c. 1.75–2 mm. long.
Morphology Reproductive morphology Seeds
Seed subglobose, black, shining, feebly reticulate, c. 1.5 mm. in diam.

Morphology General Habit
Erect or occasionally prostrate or ascending annual herb, ± 0.3–1 m. tall, much branched in the lower half and frequently also above, the lowest internodes of particularly the lower branches very divergent.
Morphology Stem
Stem and branches striate, the lower internodes terete, the upper subquadrate and ± sulcate, nodes somewhat swollen; indumentum very variable, from subglabrous or with sparse soft pubescence to dense with a double indumentum of shorter soft hairs and long fine multicellular spreading bristly hairs (even when absent elsewhere tufts of bristly hairs occur between the branches and leaves at least of the upper nodes, frequently forming a ring there).
Morphology Leaves
Main stem and branch leaves cordate-ovate to broadly ovate or rarely cordate-lanceolate, obtuse to acuminate at the apex, 1.3–7 × 0.7–5.2 cm., the lowest on petioles up to ± 1(–1.8) cm. long, leaves towards the ends of the stem and branches reducing in size and sessile; indumentum very variable, from green on both surfaces (moderately softly appressed pilose below and thinly so with long and shorter multicellular strigose hairs above) to moderately appressed pilose above and densely silvery sericeous on the lower surface.
Morphology Reproductive morphology Inflorescences
Inflorescence a large open compound panicle of axillary opposite panicles formed of simple or branched spikes, each with a flexuose glabrous rhachis; peduncle and branches of the partial inflorescences capillary, glabrous or with long strigose multicellular hairs; bracts lanceolate, 0.75–1 mm., sparingly pilose, mucronate with the excurrent midrib; bracteoles similar but slightly shorter.
Morphology Reproductive morphology Flowers
Flower sessile.
Morphology Reproductive morphology Flowers Tepal

Figures
Fig. 21/1–6.
Habitat
Mostly on sandy soil near the shore, along roadsides, beneath palms, in abandoned cultivation, grassy places, etc. at low altitudes (0–15 m.) but also inland in grassland, Acacia bushland, etc. up to 320 m.
