MONOPETALANTHUS richardsiae J. Léon. [family LEGUMINOSAE-CAESALPINIOIDEAE], in Exell & Mendonça, C.F.A. 2: 204 (1956) & in Mém. 8°, Classe Sci., Acad. Roy. Belg. 30(2): 257 (1957); F.F.N.R.: 126(1962). Type: Zambia, near Abercorn, Inono stream close to Mpulungu road, Richards 4483 (K, holo.!, BM, EA, iso.!)
MONOPETALANTHUS leonardii Devred & Bamps [family LEGUMINOSAE-CAESALPINIOIDEAE], in B.J.B.B. 30: 111, fig. 18 (1960). Type: Congo Republic, Kivu Province, Bunyakiri, A. Léonard 3331 (BR, holo., K, iso.!)
Information
Tree 3–12(–25, fide Devred & Bamps) m. high; young branchlets glabrous to shortly pubescent. Leaves with stipules quickly falling off; petiole 1–6 mm. long; leaflets in one pair, sessile, coriaceous, glabrous or almost so, semi-elliptic or semi-ovate-elliptic, l.7–7.5(–10) cm. long, 0.6–3.2(–4.5) cm. wide (to 9 × 4.5 cm. on juvenile shoots), acutely or sometimes obtusely ± acuminate at apex, rounded on outer side at base; vein-network prominent on both surfaces. Racemes 1–3.5 cm. long, brown-pubescent. Bracteoles subcircular, 4.5–7 mm. long and up to 6 mm. wide, brown-pubescent outside. Sepals 0, or 1–2 of them up to 3.5 × 2.5 mm. and 1–2 minute. Large petal white, 5–8 mm. long, 4–6 mm. wide, shortly clawed, with subcircular lamina; other petals 0, or 1–2 minute. Stamens 9–10; filaments glabrous. Pods asymmetric, ± oblong-elliptic or obovate-elliptic, 2.5–3.7 cm. long, 1.5–2.3 cm. wide, glabrescent, with 1(–2) prominent longitudinal nerves on each valve, 1–2-seeded. Seeds ± 1.2 × 0.9–1 cm., apparently dark brown. Fig. 42, p. 197.

Notes
M. richardsiae will probably be found in the SW. part of Tanganyika adjacent to Abercorn in Zambia.M. leonardii was separated from M. richardsiae by having only one petal (not two), and by having a “submedian” not “submarginal” longitudinal nerve on each valve of the pod. Fanshawe 4343 (Zambia, Kawambwa) has only one petal per flower, and is from the area of M. richardsiae, with which it is clearly conspecific. The shape of the pods and the position of the longitudinal nerve of Léonard 2227 (cited under M. leonardii) differ in no significant way from those shown by the abundant series of pods of B. D. Burtt 5995, from Zambia, Abercorn. These were, however, scarcely accessible at Kew when M. leonardii was described. I do not consider, therefore, that M. leonardii can be maintained as a distinct species.
