Nomenclatural notes — The type of Panicum villosum was recovered from the de Lamarck herbarium at P.

The type of Panicum pauperulum could not be traced at P, where most of the Leprieur collections are located, nor elsewhere. It seems likely that, similar to the situation in Panicum despreauxii , where the protologue indicated a collection by Leprieur , while the actual collector was Despreaux, the type was not collected by Leprieur himself, but was included in his herbarium, which renders its discovery problematic. Meanwhile, it remains unclear as to who actually was the first to regard the name as a synonym of U. villosa , since that person would presumably have seen the type.
