Terminalia leiocarpa

Terminalia leiocarpa (African birch; Bambara: ngálǎma) is a species of tree in the genus Terminalia. It is a deciduous tree native of tropical Africa from Senegal and Guinea in the west to Eritrea in the east and as far south as the Democratic Republic of the Congo. Terminalia leiocarpa germinates in the new soils produced by seasonal wetlands. It is a forest fringe plant, growing at the edges of the rainforest, although not deep in the rainforest. It also grows in savanna, and along riverbanks, where it forms gallery forests. The tree flowers in the rainy season, from June to October. The fruit are winged samaras, and are dispersed by ants....read more on Wikipedia.
