Morphology General Habit
Perennial, with numerous slender ascending, straggling or decumbent stems up to 4 dm. long.
Morphology Stem
Stems ribbed above, shortly covered with appressed hairs.
Morphology Leaves
Leaves 3-foliolate; leaflets oblanceolate, narrowly oblong-elliptic to obovate-elliptic, up to 12–24(–41) mm. long, 4–10 mm. wide, glabrous or rarely pubescent above, appressed puberulous beneath; petiole 2–10 mm. long.
Morphology Leaves Stipules
Stipules minute and caducous or absent.
Morphology Reproductive morphology Inflorescences
Racemes pedunculate, up to 4–11 cm. long, with ± 4–16 flowers generally rather closely arranged towards the top; bracts subulate or linear, 1–2 mm. long; bracteoles inserted at the base of the calyx, ± 1–2·5 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx ultimately truncate at the base and deflexed against the pedicel, 3–4(–4·5) mm. long, appressed puberulous or less commonly glabrous; lobes triangular, slightly acuminate, ± as long as the tube.
