Taxonomy
The taxonomic relationships of this genus were discussed by Verdcourt (1977) and Nevling & Niezgoda (l.c.). It is closely related to Leucaena, but differs by its glandular anthers and the seeds held transversely in the pods (with its peculiar mode of dehiscence). The pollen is different from Leucaena too, being arranged in tetrahedral tetrads, with individual tricolporate or porate grains, the apertures arranged in an interradial position, exine rugulate or granular.
