The Piranheiras ( Piranhea ) are a genus of tropical trees from the Picrodendraceae family , which is native to South America.

Piranheiras are diocesan trees with alternate, three-, rarely five-lobed leaves. The inconspicuous, petalless flowers are in axillary inflorescences. The fruits are three-seeded split fruits .

distribution

The species of the genus occur from Mexico to the Brazilian Amazon in tropical rainforests, especially in floodplains and along river banks.

ecology

The fruits of piranheira trees, as well as butterfly caterpillars, which partially attack the trees on a massive scale, are eaten by numerous fish, including various tetra species , when they fall into rivers . The good fishing opportunities near these trees earned them their name, which means piranha tree.
