Urticaceae, I. Friis. Flora Zambesiaca 9:6. 1991

Morphology General Habit
Perennial monoecious herbs, from short, thick, prostrate, ± thickened rhizomes.
Morphology Stem
Stems succulent, usually unbranched, up to c. 40(50) cm. tall, 1–2 cm. in diam. when fresh, shrinking to 4–5 mm. when dry.
Morphology Leaves
Leaves opposite and heteromorphous with the reduced leaves of heteromorphous pairs soon falling, usually concentrated in the upper half of the stem, petiolate; lamina up to 12 x 3 cm., somewhat asymmetrical around the midnerve, base asymmetrically cuneate, margin serrate, apex long acuminate, glabrous on both sides, lateral nerves 6–10 on either side of the midnerve.
Morphology Leaves Petiole
Petioles 2–4 mm. long.

Stipules fused, intrapetiolar, 1–3 mm. long.
Morphology Reproductive morphology Inflorescences
Inflorescences in the axils of current or fallen leaves, pedunculate. Male inflorescences rather rare, usually on the lower part of the plant;peduncles 5–10 mm. long, thin; receptacle small, fleshy, with 3–10 male flowers on 1–3 mm. long pedicels; male flowers (4)5-merous, with corniculate tepals, stamens equalling the tepals in number, ovary rudimentary. Female inflorescences in the upper leaf-axils, on rather stout peduncles, 2–6 mm. long; receptacle fleshy with 20–50 sessile female flowers; female perianth of (4)5 short, broadly ovate tepals, these covering the lower part of the erect, symmetrical, ovoid ovary which is crowned by a penicillate stigma.

Urticaceae, I. Friis University of Copenhagen, Denmark. Flora of Tropical East Africa. 1989

Morphology General Habit
Perennial herbaceous plants with short, thick and fleshy rhizomatous part, 2 cm. in diameter or more; reported to be monoecious, but no material to confirm this has been seen.
Morphology Stem
Stems fleshy, 1–2 cm. thick when fresh, but shrinking to 4–5 mm. when dry, glabrous, unbranched, arising from the thick rhizomes, reaching a height of 50 cm. or more.
Morphology Leaves
Leaves of a pair very unequal, soon falling, the smaller one usually long before the larger one; stipules completely fused, broadly triangular, 1–2 mm. long, obtuse; petiole very short, rarely up to 5 mm. long, passing gradually into the cuneate leaf-base; lamina lanceolate to oblanceolate, widest near or slightly above the middle, slightly asymmetrical, small leaves usually less than 0.8 cm. long and 0.2 m. wide, large leaves 7–15 cm. long, 1–2.5 cm. wide, base long-cuneate, slightly asymmetrical, margin serrate to crenate, rarely subentire, with up to ± 8 poorly marked teeth or crenations, apex long acuminate; lateral nerves in 6–10 pairs, not opposite, almost equally strongly developed; glabrous on both sides, cystoliths elongate, visible on both sides.
Morphology Reproductive morphology Inflorescences
Male inflorescences (rare in herbarium material and not seen from Flora area) consist of a single few-flowered cluster, up to 0.5 cm. in diameter, on a peduncle 8–10 mm. long; ♀ inflorescences consist of clusters on peduncles 1–5 mm. long, 1–2 mm. thick, each cluster 2–4 mm. in diameter.
sex Male
Male flowers on pedicels 1–2 mm. long; perianth ± 1 mm. in diameter, (4–)5-merous, with corniculate tepals.
Morphology Reproductive morphology Flowers
Female flowers sessile; perianth 4–5-merous, tepals subequal, persistent; ovary erect, with a sessile penicillate stigma. Male flowers on pedicels 1–2 mm. long; perianth ± 1 mm. in diameter, (4–)5-merous, with corniculate tepals.
sex Female
Female flowers sessile; perianth 4–5-merous, tepals subequal, persistent; ovary erect, with a sessile penicillate stigma.
Morphology Reproductive morphology Fruits
Achene ovoid, hardly compressed, ± 1 mm. long, partly enclosed in the persistent perianth.
