Ukea

Ukea is a genus of trees in the family Fabaceae, commonly found in Madagascar and East Africa. These trees are characterized by their compound leaves and their ability to fix nitrogen from the atmosphere through a symbiotic relationship with rhizobia bacteria in their root nodules. The genus name, ukea, is derived from a local Malagasy name for one of its species.

Species within the ukea genus are often valued for their hardwood, which is dense and durable, making it suitable for construction and furniture. Some species also produce edible fruits or seeds, which are utilized by local populations for food. The flowers of ukea trees are typically small and inconspicuous, appearing in clusters.

Ecologically, ukea plays a role in its native habitats by contributing to soil fertility and providing a food source and habitat for various wildlife. They are an important component of the dry deciduous forests and savannas where they are found. Conservation efforts are in place for some species that are threatened due to habitat loss and overexploitation. Research into the genetic diversity and ecological importance of ukea is ongoing.
