Morphology General Habit
Erect rather bushy annual or short-lived perennial, up to 1·3 m. tall.
Morphology Stem
Stem densely covered with appressed or slightly spreading white hairs.
Morphology Leaves
Leaves 3-foliolate; leaflets elliptic or obovate, up to 40–74 mm. long, 16–34 mm. wide, obtuse, rounded or retuse at the apex, subglabrous above, usually with small hairs only along the midvein, appressed pubescent beneath; petiole ± 15–25 mm. long.
Morphology Leaves Stipules
Stipules subulate or filiform, up to 2–5 mm. long, rather persistent.
Morphology Reproductive morphology Inflorescences
Racemes up to 15–30 cm. long, with many fairly closely arranged flowers; bracts linear or subulate, 1–3 mm. long; bracteoles inserted at the base of the calyx, subulate to oblong-triangular, up to 1·5–2 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx ± 5 mm. long, thinly appressed pubescent; lobes triangular, ± as long as the tube or shorter.
Morphology Reproductive morphology Flowers Corolla
Standard suborbicular, clear yellow, turning reddish, particularly on the veins, glabrous or with a few small hairs medially towards the apex outside; wings a little longer than the keel; keel rounded about the middle, with a practically straight rather projecting untwisted beak, 10–12 mm. long.
Morphology Reproductive morphology Fruits
Pod shortly stipitate, asymmetrically oblong-clavate, (20–)23–30 mm. long, 5–6 mm. across, densely pubescent, ± 12–16-seeded.
Morphology Reproductive morphology Seeds
Seeds oblique-cordiform, ± 3 mm. long, smooth, brown.
