A considerable genus, of whicli a fow species appear to be limited to tropical America or 

 to Australia, the remainder generally dispersed over various tropical regions in the Old as 

 well as the New World. Of the 13 Australian species 9 arc endemic, the remaining 4 arc 

 common weeds in tropical Asia and Africa. The fruit in this genus is often indispensable 

 for determining the species.
