A monotypie genus at present known only from Celebes and the Pliilippines. 

 gi'owing especially near the seashore, but also occurring inland and at considerable 

 altitudes. It undoubtedly belongs in the Miniosoidedc-Ingeae, although in fruit 

 characters it is closer to some of the genera in M i Diosoideae-Piptadeiiieae. It is 

 well characterized by its deliiscent pods, the exocarp of which is not transversely 

 jointed, and whicli is free from tlie transverse!}- septate endocarp, the latter 

 forming a somewhat loose, parchment-like, more or less inflated envelope surround- 

 ing each seed, (juite similar to that of Entuda. and doubtless an adaptation 

 for dispersal of the seeds by water. The timber is of considerable value, and 

 has been considered l)v Foxworthy,'- under the head of Banui/o.
