Smithia elliotii Baker f.

Protologue
Legum. Trop. Africa 2: 304 (1929).
Family
Papilionaceae (Leguminosae - Papilionoideae, Fabaceae)
Origin and geographic distribution
Smithia elliotii is recorded from Nigeria, Cameroon, DR Congo, Burundi, Ethiopia, Kenya, Uganda, Tanzania, Malawi, Zambia, Mozambique and Madagascar.
Uses
In Malawi the leaves of Smithia elliotii are cooked and eaten as a side dish. The leaflets are separated from the rachis and cooked with the addition of potash. The cooked product is so slippery that most of it runs back into the dish when a lump of porridge is dipped in; hence it goes a long way. The dish is frequently eaten by women and children and is prepared especially for babies and invalids. Vegetable use has been recorded from DR Congo as well, but no details have been published.
Botany
Decumbent herb up to 180 cm long. Leaves alternate, paripinnate with 10–28 leaflets; stipules with a basal extension, up to 3.5 cm long; petiole 2–5 mm long, rachis 1.5–5.5 cm long; leaflets linear-oblong, 3–15 mm × 1–5 mm, base obliquely rounded, apex rounded to acute, apiculate. Inflorescence umbellate, 1–1.5 cm long, dense, up to 12-flowered; bracts early caducous. Flowers bisexual, papilionaceous; calyx c. 1 cm long, covered with yellow bristles; corolla purplish, standard c. 1 cm long. Fruit a pod with 4–7 segments, each segment 2–3 mm long and wide.
Smithia comprises about 30 species, most of them from Asia and Madagascar. Smithia erubescens (E.Mey.) Baker f. is restricted to South Africa and Swaziland and records for this species from tropical Africa refer to either Smithia elliotii or to Smithia abyssinica (A.Rich.) Verdc., an Ethiopian endemic.
Ecology
Smithia elliotii is found in coarse grassland in glades, along streams and in swamps, sometimes even growing in standing water, at 1150–2700 m altitude.
Management
Smithia elliotii leaves are collected from the wild, and they are commonly sold in local markets in Malawi. There are no recent records on cultivation.
Genetic resources and breeding
The risk of genetic erosion is limited because Smithia elliotii is widely distributed and not uncommon.
Prospects
Smithia elliotii will remain of interest as a vegetable only locally.
