Distribution
Distribution. The species occur in evergreen or semideciduous equatorial or gallery forest with 1000 – 4000 mm precipitation per annum (ppa), apart from the Angolan Mischogyne michelioides Exell which occurs in rocky terrain beneath the coastal escarpment with 650 – 1000 mm ppa
Ecology
No scientific observations of dispersal are known. Dispersal of Mischogyne congensis by snakes cannot be ruled out. “Les indigènes prétendent que les serpents mangeant beaucoup le fruit de cet arbuste.” (Gilbert, G.C. 2321bis). No studies have been done regarding pollination. Saunders (2012) observed that the lack of a pollination chamber is “typical of small-beetle pollination”. Evergreen or semideciduous equatorial or gallery forest, with 1000 – 4000 mm precipitation per annum (ppa); except Mischogyne michelioides: rivers, sandy areas, or among rocks at altitude 600 – 1000 m and 650 – 1000 mm rainfall ppa.
Morphology General Habit
Trees or shrubs (shrubs or small trees 3 – 7 m tall or medium-sized trees to 25 m)
Morphology General Indumentum
Very young leaf buds, leaves, and twigs with a soft brown indumentum of appressed hairs, quickly glabrous or glabrescent
Morphology Leaves
Leaves simple, entire, alternate, petiolate and exstipulate, lamina narrowly elliptic to obovate, chartaceous to coriaceous, often slightly bullate, glabrous to pubescent; dark glossy green above, lighter green below, drying olive green concolorous or paler below; midrib impressed on the upper side, raised on the lower side, glabrescent; secondary venation brochidodromous, prominent above and below; tertiary venation markedly reticulate on both surfaces of the lamina with reticulation net cells 0.6 – 1.8 mm wide
Morphology Leaves Petiole
Petioles terete, deeply grooved adaxially, glabrous to densely pubescent
Morphology Reproductive morphology Flowers
Flowers bisexual-Sepals 3, reduplicate-valvate, free, enclosing the receptacle until anthesis, or united in a thin membranous capsule rupturing at anthesis (M. gabonensis)
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens numerous, spirally arranged, linear, latrorse, basifixed, appressed at least in lower part against the torus; filament minimal or absent; connective and thecae nearly the length of the anther; connective pubescent or glabrous, without expanded terminal extension, connective apex glabrous or terminated by a tuft of hairs
Morphology Reproductive morphology Flowers Calyx
Sepals, petals and stamens dropping at end of anthesis, leaving the receptacle and carpels exposed
Morphology Reproductive morphology Flowers Corolla
Petals 6, in two alternating whorls of three each, white, free, subequal, elliptic to ovate, pubescent, reflexing at anthesis except M. michelioides where the petals spread from the base
Morphology Reproductive morphology Flowers Gynoecium Carpels
Carpels 3 – 12 (to 40 in M. michelioides), cylindrical to ovoid, densely pubescent; style short or absent, stigma bilobed, ovules numerous, lateral, biseriate, placentation parietal-Fruits monocarps 1 – 3, ellipsoid, oblong to globose, pubescent to glabrous, smooth or with slight longitudinal ribs, constricted or not around the seeds, shortly stipitate, apiculate
Morphology Reproductive morphology Flowers Receptacle
Receptacle extended as a torus, conical, cylindrical, or elongate in a thin flexible column, with stamens attached to the lower portion and carpels attached at the apex
Morphology Reproductive morphology Inflorescences
Inflorescence extra-axillary or terminal (M. michelioides) on young branches, single flowered (occasionally two flowers in M. gabonensis)
Morphology Reproductive morphology Inflorescences Bracts
Bracts generally reduced to a tuft of hairs or early caducous
Morphology Reproductive morphology Seeds
Seeds 3 – 12 per monocarp, flattened to transversely ellipsoid, raphe raised to flat, ruminate with 15 – 20 membranous semi-circular invaginations.
Morphology Trunk
Trunk straight, sometimes fluted, cylindrical, or shrubs branching from the base (M. michelioides)
Morphology Twigs
Twigs striate, light grey to dark grey to brown
Note
μίσχος = stalk (Greek) + gyne for the elongate gynoecium of Mischogyne michelioides, the type species.
Type
Type species: Mischogyne michelioides Exell

Use
Mischogyne congensis is used against snake bites (Gilbert 2321bis); M. michelioides for treatment of swollen legs (Damann 2557) and against madness (Santos 252). Mischogyne elliotiana var. sericea is used to clean hats and other cloth (Deighton 510).

Native to:

Angola, Benin, Cameroon, Gabon, Ghana, Guinea, Guinea-Bissau, Gulf of Guinea Is., Ivory Coast, Liberia, Nigeria, Sierra Leone, Tanzania, Zaïre
