This plant is nearly allied to the gonus Pentzia, but the opposite 
leaves, almost exceptional in the tribe, and the achenes showing at 
least in the unripe state twelye to fifteen prominent ribs instead of five 
angles, induced me to establish it as a distinct genus. The forked 
leaves are also peculiar.—G, BenTHam.
