Morphology General Habit
Annual herb up to c. 1 m. tall, erect and branching or sometimes with decumbent branches if the main stem is cut down or browsed; branchlets often purplish and when young with a spreading setulose pubescence not confined to one side of the stem.
Morphology Leaves
Leaf-lamina 2–12 × 0·5–3·5 cm., lanceolate to oblong or narrowly oblong, apex acute or subacute, margin crenate-serrate, usually with a pair of setaceous basal appendages, rounded or broadly cuneate at the base, glabrous or setulose-pilose on both surfaces especially on the nerves; petiole up to 2–5 cm. long when low down on the stems but usually rather shorter, with a spreading setulose pubescence especially on the upper side; stipules c. 1 cm. long, setaceous, setulose-pubescent.
Morphology Reproductive morphology Inflorescences
Inflorescences of 1–3-flowered cymes borne opposite the upper leaves; peduncles c. 1 mm. long but lengthening in fruit, setose-pubescent; pedicels similar, c. 1 mm. long.
Morphology Reproductive morphology Flowers Calyx
Sepals 6–10 mm. long, narrowly lanceolate, usually caudate at the apex, often somewhat keeled, setulose-pubescent particularly on the keel.
Morphology Reproductive morphology Flowers Corolla
Petals yellow, the same length as the sepals, oblanceolate, with a short ciliate claw at the base.
Morphology Reproductive morphology Flowers Androgynophore
Androgynophore c. 0·5 mm. long, extended above into a slightly undulate annulus.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 30–40.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary trigonously subcylindric, very shortly pubescent, 3 (4)-locular; style 1–1·5 mm. long, glabrous.
Morphology Reproductive morphology Fruits
Capsule many-seeded, 2·5–7 cm. long, held erect, straight or slightly curved, 3–1-angled, 3–valved; valves scabrous and sometimes somewhat torulose outside, with a series of hollows inside fitting the seeds.
Morphology Reproductive morphology Seeds
Seeds dark brown, 1–1·3 × 0·7–1 mm., oblong-ovoid.
