Panicum aciculare Desv.; Poir. in Lam. Encycl. Suppl. 4: 274. 1816; Contr. U. S. 
Nat. Herb. 15: 166. 1910. 
In the discussion of the type specimen it is stated that it probably came from the 
southeastern United States. As the species is now known to occur in Porto Rico, it 
becomes probable that this island is the type locality, since Desvaux described many 
species from there.
