Oldfieldia africana, also known as the African oak, is a large tree which can grow to 36 metres or more in height.[1] It is to be found across West Africa in such countries as Ivory Coast, Liberia, Sierra Leone, Gabon, Cameroon, Central African Republic, Congo Republic.[2]
Numbers have decreased as its timber is very heavy and hard, comparable to teak. John MacCormac an Irish businessman who settled on the banks of the Rokel River, Sierra Leone for example, established the local timber trade in 1816, and for a while enjoyed a substantial income from it.[3]
The bark maybe used as an antiseptic and haemostatic.[1] It can also be added to various herbs in order to increase their potency.[1] Another use is a decoction of the barkwhich can be added to baths or draughts as a treatment for blennorrhoea.[1] The powdered bark can be used in a dressing to hasten healing or to treat sores.[1] The bark can be boiled with palm-oil to make an ointment, to treat lice infestation or the leaves can be used in a similar way.[1]

Oldfieldia africana Benth. & Hook.f. (connue sous le nom de « chêne d'Afrique ») est une espèce de plantes de la famille des Picrodendraceae et du genre Oldfieldia, présente en Afrique tropicale.
C'est un grand arbre pouvant atteindre 40 m de hauteur[2].
D'abord connue en Sierra Leone et en Côte d'Ivoire, l'espèce est également présente au Cameroun, où Mildbraed découvrit notamment un spécimen imposant, à large couronne, le 10 janvier 1911, aux environs de Moloundou[3].
Le bois de Oldfieldia africana est sans doute l'un des plus anciens importés en Europe depuis l'Afrique de l'Ouest. Utilisé dès le XVIIIe siècle en Grande-Bretagne pour la construction navale, en remplacement du chêne, il fait toujours l'objet d'un commerce international, mais en moindres quantités[2].
L'écorce connaît de multiples usages, notamment médicinaux[4].
L'arbre lui-même joue un rôle significatif lors de certaines cérémonies rituelles[4]. Les coques de ses fruits, réunies dans une corbeille, sont utilisées comme instrument de divination chez les Banen du Cameroun[5].
