Chamaecrista falcinella (Oliv.) Lock

Protologue: Kew Bull. 43(2): 336 (1990).

Family: Caesalpiniaceae (Fabaceae, Leguminosae)

Synonyms

• Cassia falcinella (Oliv.) Lock

Origin and geographic distribution

Chamaecrista falcinella occurs in DR Congo, Rwanda, Kenya, Uganda, Tanzania, Zambia, Namibia, Botswana, Zimbabwe and Mozambique.

Uses

Medicinal plants

Properties

No data have been published on the properties of Chamaecrista falcinella. Several interesting compounds with pharmacological activities have been isolated from other Chamaecrista spp.

Botany

Annual or perennial herb up to 60 cm tall. Leaves alternate, paripinnate with 5–17 pairs of leaflets; stipules falcate, slightly cordate at base; petiole with sessile gland, rachis without gland; leaflets sessile, elliptical, up to 17 mm × 3 mm, midrib asymmetrical, apex acute with prickle-like point bent sideways. Inflorescence a 1–3-flowered raceme. Flowers bisexual, nearly regular, 5-merous; pedicel 1–2.5 cm long, hairy; sepals acute, pubescent; petals obovate, up to 10 mm long, yellow; stamens 8–10; ovary superior, 1-celled, style curved. Fruit a pod up to 4.5 cm × 0.5 cm. Seeds rhombic, c. 3 mm long.

Chamaecrista comprises about 250 species with about 40 species in continental Africa, and 10 in Madagascar, 6 of them endemic. Chamaecrista falcinella is variable, and several varieties are distinguished.

Chamaecrista zambesica (Oliv.) Lock (synonym: Chamaecrista hildebrandtii (Vatke) Lock) is also used in traditional medicine. In Kenya the leaves and roots are used as a cathartic against the intestinal protozoal parasite Giardia lamblia. Laboratory tests confirmed the lethal effect on the parasite. Chamaecrista lateriticola (R.Vig.) Du Puy is endemic to Madagascar, where a leaf infusion is taken against stomach-ache.

Ecology

Chamaecrista falcinella is found mainly in grassland at 1000–1800 m altitude.

Genetic resources

Chamaecrista falcinella is widely distributed and hence not threatened with genetic erosion. It is not present in major germplasm collections.

Prospects

In view of its medicinal uses, the complete lack of chemical and pharmacological data and the medicinal properties of other Chamaecrista species, research on the properties of Chamaecrista falcinella may prove worthwhile.
