*''Kerstingiella geocarpa'' Harms (1908).

*Kersting’s groundnut, geocarpa groundnut, ground bean (En). *Lentille de terre, fève de Kandale, doï, dohi (Fr).

*Annual herb with prostrate rooting stems; stem pubescent or almost glabrous, up to 10 cm long. *Leaves alternate, 3-foliolate; stipules triangular-ovate, 2–7 mm long, pubescent; petiole erect, up to 25 cm long; rachis c. 7 mm long; stipels linear-lanceolate, 2–5 mm long; petiolules hirsute, lateral ones 1–2 mm long, terminal one 4–10 mm long; leaflets broadly ovate or obovate, 3–8 cm × 2–5.5 cm, glabrous, 3-veined from the base. *Flowers in pairs or solitary in leaf axils, bisexual, papilionaceous, almost sessile; bracteoles lanceolate, (1–)3.5–4 mm long; calyx pilose, tube 2–2.5 mm long, lobes linear-lanceolate, (2–)3.5–4 mm long; corolla white or greenish-white, sometimes tinged with purple, standard 6–10 mm × 4.5–6 mm, wings 6–7 mm × 1.5 mm, keel 5.5–6 mm × 1 mm; stamens 10, 9 fused and 1 free; ovary superior, shortly stalked but stalk elongating during fruit development, 1-celled, style slender, curved, stigma minute. *Fruit an indehiscent pod 0.5–2.5 cm × 0.5–1 cm, on a stalk up to 2 cm long, (1–)2(–3)-seeded, constricted between the seeds, maturing on or below the soil surface. *Seeds oblong or oblong-ovoid, 5–10 mm × 4–7 mm × 3–5 mm, whitish, red, brown or black, sometimes striped, spotted or speckled. *Seedling with epigeal germination, with cotyledons falling off about 2–3 days after emergence and 2–3 simple lanceolate primary leaves persisting until maturity.

– * var. ''geocarpum'': internodes short, petiole 8–25 cm long, terminal leaflet up to 7.5 cm × 5 cm, pod (1–)2(–3)-seeded, seed c. 9 mm × 6 mm; only known from cultivation;

– * var. ''tisserantii'' (Pellegr.) Maréchal & Baudet: internodes long, petiole up to 1 cm long, terminal leaflet up to 3.5 cm × 2.5 cm, pod 1(–2)-seeded, seed c. 5 mm × 4 mm; found wild in Cameroon and the Central African Republic, and perhaps better considered a separate species (originally described as ''Kerstingiella tisserantii'' Pellegr.), which is supported by the results of isozyme analysis and possibly also chromosome number.
