Salacia mannii Oliv.

Fl. trop. Afr. 1: 376 (1868).
Celastraceae (Hippocrateaceae)
Salacia soyauxii Loes. (1894).
Origin and geographic distribution
Salacia mannii is distributed from Nigeria eastwards through Cameroon, Equatorial Guinea and Gabon to DR Congo. It has not been recorded in Congo.
The stems of Salacia mannii are extremely strong and in DR Congo they are made into snares to trap elephants. Many Salacia species produce edible fruits but for this specific species this has not been confirmed.
Shrubby bush, sometimes scandent, up to 6 m tall or woody liana up to 15 m tall; bark warty, lenticellate; twigs green becoming reddish brown. Leaves opposite or subopposite, simple; stipules absent; petiole 3–10 mm long; blade elliptical, 8–23 cm × 2.5–9 cm, rounded to obtuse at base, acuminate at tip, margin entire or slightly dentate, deep green and glossy above, paler beneath, with 5–8 pairs of secondary veins. Inflorescence an axillary glomerule with up to 10 flowers. Flowers bisexual, yellow to whitish, 5–10 mm in diameter; pedicel 5–24 mm long; calyx 5-lobed, lobes unequal, up to 2.5 mm wide; petals 5, cream, free, 2–5 mm × 1.5–2 mm; stamens 3, yellow, 0.5–1.5 mm long; ovary 3-celled, yellow, style weakly 3-lobed, very short. Fruit ovoid to elliptical, 4–7 cm × 2.5–3.5 cm, with base and tip attenuate, orange-red when ripe, 2–6-seeded. Seeds 10–22 mm long.
Salacia comprises 180–200 species distributed throughout the tropics, with c. 30 species in America and c. 90 in Africa. The forests of Cameroon and Gabon house around 60 species and Madagascar only 2.
Salacia mannii occurs in forest and gallery forest from sea-level up to 900 m altitude.
Genetic resources and breeding
There are no known germplasm collections of the species and there is no apparent threat for Salacia mannii.
As a plant resource Salacia mannii will not play an important role in future unless new utilisations are discovered.
