Habit
Annual (always?) herb, up to 1·2 m. high; stems simple or moderately branched, erect or semi-prostrate, succulent, glabrous or sometimes somewhat pubescent mainly on younger parts.
Leaves
Leaves spirally arranged, very rarely pseudopposite, petiolate; lamina 3–10 (14) × 1–2·5 (4) cm., lanceolate-elliptic, ovate-lanceolate or very rarely obovate-lanceolate, usually dark green on the upper surface, greyish-green on the lower one, glabrous above, shortly pilose or rarely glabrous beneath, apex acute, often acuminate, margin serrate-denticulate, base cuneate; secondary nerves 6–10 pairs, ± prominent beneath; petiole 0·5–3 (4) cm. long, rather slender, usually glabrous, with stipular glands at the very base.
Flowers
Flowers 2–6 in axillary fascicles, very rarely solitary, green-yellow tipped orange-red, scarlet shaded yellow, or orange; peduncle very short, not exceeding 4 mm.; bracts up to 4 mm. long, lanceolate-triangular, pilose or glabrous; pedicels 1·5–2·5 (4) cm. long, rather slender, glabrous or sometimes pubescent.
Calyx
Lateral sepals 4–7 × 1–2 (2·5) mm., ± asymmetrically lanceolate, triangular-lanceolate to ovate-lanceolate, usually glabrous; posterior sepal 7–9 mm. in diam. at the mouth, 1·5–2 (2·4) cm. deep, bucciniform, gradually tapering into the spur; spur up to 8 mm. long, sharply recurved (see t. 26 fig. 1), medium thick, ± cylindric, the end somewhat thickened, entire or very rarely inconspicuously bifid.
Corolla
Anterior petal 7–12 mm. long, helmet-shaped, dorsally distinctly and broadly cristate; lateral united petals (7) 8–10 (12) mm. long, distinctly 2-lobed; anterior lobe c. 4·5–2·5 mm., obliquely elliptic to obovate-oblong; posterior lobe c. 7 × 4 mm., obliquely and broadly ovate.
Ovary
Ovary glabrous.

Balsaminaceae, C. Grey-Wilson. Flora of Tropical East Africa. 1993

Habit
Erect perennial, perhaps occasionally annual, to 1.5 m. tall; stems simple or rather poorly branched, sometimes somewhat decumbent, glabrous or sparsely pubescent on the youngest parts.
Leaves
Leaves spirally arranged, often rather dense; petiole 2–30 mm. long; lamina elliptic to ovate-lanceolate or elliptic-obovate, 3–9.5 cm. long, 1.6–6 cm. broad, the apex acute or shortly acuminate, the base cuneate, glabrous above or with a few hairs along the midrib, finely pubescent beneath, rarely subglabrous; lateral veins 6–10 pairs, the secondary veins forming a rather distinct reticulate pattern beneath; margin serrate-denticulate to crenulate.
Flowers
Flowers in axillary fascicles of 2–5(–6), rarely solitary, epedunculate or borne on a very reduced peduncle not exceeding 4 mm. in length, the colour variable from pale yellowish green to greenish orange, flowers with a yellowish spur-sepal and orange or reddish petals being the commonest form.
Bracts
Bracts linear-lanceolate, 1.5–4 mm. long, inconspicuous.
Pedicel
Pedicels 1.8–4.5 cm. long, slender, glabrous or sparsely pubescent, ascending to horizontal in flower, but becoming ± pendent in fruit.
Calyx
Lateral sepals 2, lanceolate or narrowly triangular, 4–7 mm. long, usually glabrous. Lower sepal rather narrowly to broadly saccate, 5–8(–9) mm. long, 15–20 mm. deep, ± abruptly constricted into a 5–8 mm. long incurved spur, swollen and often somewhat bilobed at the tip, glabrous, or sparsely pubescent in the distal half.
Corolla
Dorsal petal 11–14 mm. long, 7–11.5 mm. broad, cucullate, dorsally with a broad crest terminating in a short acute point. Lateral united petals 6–8 mm. long; upper petal obliquely ovate or ± rhombic, 6–10 mm. long, 4–7.5 mm. broad; lower petal oblong or elliptic, 4.5–9 mm. long, 2.5–6 mm. broad.
Ovary
Ovary glabrous.
Fruits
Fruit broadly fusiform, 18–20 mm. long, 6–8 mm. broad.
Figures
