Information
Annual, with a very short stem, soon developing numerous slender radiating prostrate branches up to 5–50 cm long, pilose, exceptionally perennating with other stems from the top of an undivided taproot. Leaves opposite on flowering shoots, 3-foliolate; leaflets 4–8(20) × 1.5–3(4) mm, oblanceolate, slightly apiculate, glabrous to pilose above, pilose beneath; petiole ± as long as the leaflets or a little shorter; stipules single at a node, 2–4 mm long, linear to linear-lanceolate or linear-oblanceolate. Flowers 1–several clustered at the nodes, sessile; bracts 1–2.5 mm long, linear; bracteoles absent. Calyx 3.5–4.5(6) mm long, pilose; upper and lateral lobes joined slightly higher, 1.5–2.5(3) mm long, subulate. Standard pale yellow, shorter than the keel, narrowly elliptic-ovate, extensively pubescent outside; wings distinctly shorter than the keel; keel 6–7(9) mm long, narrow, slightly upcurved to the bluntly pointed reddish tip, extensively pubescent. Pods 4–7(9) × 1.5–2.5 mm, narrowly oblong, often somewhat tapered to the base, slightly downcurved at the tip, pubescent, sometimes glabrescent, c. 10-seeded. Seeds 1–1.5 mm long, oblique-cordiform, smooth, brown.
Habitat
Open ground, roadsides, cultivated ground and other disturbed places or in short grassland on sand
Range
Widely distributed in the drier parts of Africa and west Asia, from the Cape Verde Is., through North Africa and the Sahel to W Pakistan, and from Arabia and the Horn of Africa to northern Tanzania, then disjunctly south to southern Angola, the Flora Zambesiaca region, Namibia and the westerly part of South Africa.

Notes
Notably variable over its wide range and particularly so in the western parts of southern Africa, as discussed by van Wyk (loc. cit.). The gatherings from SE and SW Botswana are larger in all parts, the figures given in brackets in the description above. The specimens named as this species from the mountainous Eastern Districts of Zimbabwe belong to the atypical form of L. calycina, described above, but are deceptively similar. In the Flora Zambesiaca area, L. platycarpa only very exceptionally perennates (as in Hansen 3080, cited above), having a short erect stem and many radiating branches from an undivided taproot, the leaves on the flowering shoots are more strictly opposite and the flowers of the normal Zimbabwean form of the species are smaller and probably generally paler in colour.R.M. Davies 1224 (SRGH), the specimen cited for Lotononis sp. 4 (Davies 1224) of Drummond in Kirkia 8: 223 (1972), has not been seen, but as an annual from the Southern Province of Zimbabwe is most likely to be this species or the next.
