What appears to be the same species is found in western South America. Among 
the specimens is Lechler 2219 from Peru, which was mentioned without description 
by Steudel ! in his list of Lechler’s plants, under the name Panicum megacarpum. 
This name appears not to have been published, though it is given as a synonym by 
Grisebach, Doell, and others under Panicum divaricatum or some of its allies.
