Listia subulata (B.-e.van Wyk) B.-e.van Wyk & Boatwr.

Prostrate herbaceous perennial, up to 1 m in diameter. Branches slender, prostrate, spreading from a woody caudex, often rooting at the nodes to form dense mats, thinly and minutely pubescent. Leaves digitately trifoliolate, very variable in size and shape, adaxially glabrous, abaxially thinly and minutely pubescent, at length glabrescent, somewhat fleshy; petiole slender, (5-)7-24(-60) mm long; leaflets variable in size and shape, linear, narrowly elliptic to oblanceolate, the terminal one (4-)10-28(-36) x (1-)2-5(-7) mm, the lateral ones similar but smaller. Stipules up to 5 x 3 mm, dimorphic (the one large and foliaceous, the other similar or more often much smaller), ovate to narrowly lanceolate; base cordate; apex acute; minutely pubescent. Inflorescences leaf-opposed or subterminal on lateral branches, slender, 20-120 mm long, sparsely 1-4-flowered; bract linear to narrowly oblanceolate, 2-3 mm long; bracteoles linear, ±1 mm long. Flowers 8-10 mm long, yellow. Calyx 4-6 mm long, with the upper and lateral lobe on either side fused higher up in pairs, minutely but distincdy pubescent; lobes very long and narrow, the free part up to 3 mm long. Standard orbicular, ± as long as the keel. Wing petals oblong, only slightly shorter than the keel. Keel petals elliptic; apex obtuse. Anthers dimorphic. Pistil 12-14 mm long; ovary oblong-linear, 8-10 mm long, pubescent; style short. Pods 10-15 x 2-4 mm, invariably folded like a concertina, ±12-seeded, upper suture ± smooth, indehiscent, distincdy pubescent at maturity. Seeds small, ±1 mm in diameter, testa nearly smooth.
