Cassia sparsa

Annual herb with prostrate and ascending stems forming a low bushy plant about 1–1.5 m. in diameter and under 30 cm. high; sometimes stems erect, branched or subsimple, up to 90 cm. high. Stems varying from puberulous with short curved hairs to subglabrous, without longer spreading hairs. Leaves narrowly or linear-oblong, mostly (3.5–)4.5–9 cm. long, 1–2.3 cm. wide; gland near top of petiole, sessile, ± circular or very broadly elliptic, concave or depressed on upper side, 0.5–0.8, rarely to 1.0 mm. long, 0.5–0.8 mm. wide, dark purplish-red; rhachis eglandular, channelled but not crenate-crested along upper side; leaflets sessile, usually in (17–)25–35 pairs, linear-oblong, 4.5–13 mm. long, 1.25–2.5 mm. wide, acuminate, glabrous on surfaces (except in basal leaflets of leaves); midrib somewhat excentric (towards anticous margin) but giving off ± prominulous lateral nerves towards both margins. Inflorescences mostly supra-axillary, 2–4-flowered; pedicels 0.6–1 (–1.2, rarely in fruit elongating to 1.5) cm. long, puberulous and with longer spreading hairs, sometimes subglabrous. Petals yellow, 7–8.5 mm. long, 3–7 mm. wide. Pods 3–6 cm. long, 3.5–5.5 mm. wide. Seeds brown, ± 3–4 mm. long, 1.5–3 mm. wide, not areolate. Fig. 10/42, p. 57.
