Characteristics

Annual herb, erect or spreading, stout and rather rigid, up to 1.5 m. tall.. Stem rather densely covered with stiff, mostly spreading, long (especially towards the base) hairs.. Leaves petiolate, 5–7-foliolate; leaflets oblanceolate, oblong-oblanceolate to obovate, 3–4.2 cm. long, 0.7–1.3 cm. wide, very obtuse but not or rarely rounded at the apex, strigose; petiole up to 7 cm. long.. Inflorescence stout, 35 cm. or more long.. Sepals lanceolate, 11–12 mm. long, rarely less, with a wavy caudate blackish-red apex, usually not strigose but with abundant stalked glands.. Petals pale-or rose-pink, paler than in the preceding species, even when dried, the upper pair with a yellow or white spot.. Stamens 9–14; staminodes 2–3, rarely present.. Gynophore (l–)2– 2.5 cm. long.. Capsules (3.5–)5–6.5 cm. long, glabrous or nearly so.. Seeds 1–1.2 mm. in diameter, dark brown with low transverse ridges.. Fig. 1/6, 7, & 2/12, p. 10.
More
Leaves 3–5-foliolate, petiolate; leaflets 0.75–2.5 x 0.3–1.5 cm., reducing in size upwards and passing gradually into the sessile and finally simple bracts, narrowly obovate to obovate, rounded or truncate at the apex, cuneate at the base, harshly strigillose-pubescent on both sides, nerves somewhat impressed above and prominent below, petiole up to 2.5 cm. long, pubescent like the branches.
Stamens 10–13, about the same length as the petals; filaments slender, sometimes purplish towards the base and with the shortest one, or occasionally the shortest two, swollen just below the anther; anther-thecae up to 2.5 mm. long, linear-oblong.
Capsule up to 7 x 0.3 cm., on a glabrous gynophore up to 1.8 cm. long, linear, tapering at both ends, with a persistent style up to 2.5 mm. long; valves minutely strigillose or pubescent, with about 3 longitudinal nerves.
Petals up to 2.5 x 0.5 cm., rose-coloured or purplish, becoming yellow towards the base, with an oblong-lanceolate lamina gradually narrowing into a basal claw of about the same length.
Inflorescence racemose and terminal on the branches, moderately dense at first but the internodes elongating in fruit; pedicels up to 1 cm. long, slender, with short glandular hairs.
Erect or spreading herb c. 0–6 m. tall: branches striate with a coarse, whitish pubescence of longish hairs, some shorter hairs and scattered, subsessile, glandular hairs.
Ovary linear, with a very minute pubescence visible only above a magnification of x 25; style very short; stigma hardly wider than the style.
Sepals up to 8 mm. long, linear-lanceolate, acuminate or caudate-acuminate at the apex, with short, glandular hairs on both sides.
Seeds c. 1.5 mm. in diam., dark brown, almost black, transversely ridged.
