Centroplacus glaucinus Pierre
- Protologue: Bull. Mens. Soc. Linn. Paris, ser. 2, 1: 115 (1899).
- Family: Pandaceae
Synonyms
Microdesmis paniculata Pax (1899).
Vernacular names
Origin and geographic distribution
Centroplacus glaucinus occurs in Cameroon, Equatorial Guinea and Gabon.
Uses
In Gabon a leaf decoction is taken to treat schizophrenia.
Botany
Dioecious small to medium-sized tree up to 20 m tall; bark surface dark brown, inner bark red; twigs slender, terete, glabrous. Leaves alternate, simple; stipules triangular, tiny; petiole up to 4 mm long, blackish when dry; blade oblong to elliptical-oblong, 7.5–17.5 cm × 2.5–6.5 cm, base obtuse, apex acuminate, distantly and shallowly toothed, glabrous, shiny above, pinnately veined with 10–14 pairs of lateral veins. Inflorescence an axillary panicle up to 7.5 cm long, on young shoots, short-hairy; bracts spoon-shaped, c. 1 mm long. Flowers unisexual, 5-merous; pedicel c. 1 mm long; sepals ovate, c. 1 mm long, obtuse, yellowish short-hairy; male flowers with petals broadly obovate or obovate-elliptical, c. 3 mm long, white, short-hairy, disk cup-shaped, stamens with short filaments; female flowers without petals, disk saucer-shaped, fleshy, 5-lobed, ovary superior, ovoid, c. 1 mm in diameter, 3-celled, densely short-hairy, styles 3, short. Fruit an oblong-ellipsoid, slightly 3-lobed capsule c. 7 mm in diameter, densely short-hairy, green turning pinkish orange, 3-seeded. Seeds ellipsoid, c. 3 mm long, usually smooth, black, shiny, aril orange-red.
Centroplacus consists of one species only. It has formerly been placed in Flacourtiaceae and Euphorbiaceae, but is now considered to belong to Pandaceae, although recent molecular studies indicate that it may be better placed in a separate family Centroplacaceae.
Ecology
Centroplacus glaucinus occurs as an understorey tree in primary and secondary forest, usually at low altitudes.
Genetic resources
There are no signs that Centroplacus glaucinus is threatened by genetic erosion.
Prospects
Centroplacus glaucinus will remain of local importance only as a medicinal plant.
