Anogeissus leiocarpa (African birch; Bambara: ngálǎma) is a tall deciduous tree native to savannas of tropical Africa. It is the sole West African species of the genus Anogeissus, a genus otherwise distributed from tropical central and east Africa through tropical Southeast Asia. A. leiocarpa germinates in the new soils produced by seasonal wetlands and grows at the edges of the rainforest, although not in the rainforest, in the savanna, and along riverbanks forming gallery forests. The tree flowers in the rainy season, from June to October. The seeds, winged samaras, are dispersed by ants.
