Senegalia polyphylla

Senegalia polyphylla, formerly placed in the genus Acacia, is a medium-sized to large tree in the legume family (Fabaceae, subfamily Mimosoideae) native to the seasonally dry forests, cerrados, and caatinga of tropical South America, particularly Brazil, Bolivia, and Paraguay. It typically reaches 8 to 20 meters in height, with a slender trunk and an open, spreading crown. The young branches and rachises bear scattered small recurved prickles characteristic of the genus Senegalia. The leaves are bipinnately compound and finely divided, with numerous (typically 15 to 40) pairs of pinnae each bearing many tiny oblong leaflets, giving the foliage a delicate, feathery appearance and inspiring the specific epithet polyphylla ('many-leaved'). Small, fragrant, creamy-white to pale yellow flowers are crowded into globose or short cylindrical heads borne in axillary panicles. The fruits are flat, oblong, dehiscent legume pods containing several flattened seeds. The wood is hard and durable and used locally for fuel, charcoal, and construction.
