NEW COMBINATIONS IN DICHANTHELIUM (POACEAE).

Ongoing examination of Panicum sensu lato in the grass tribe Paniceae (Poaceae) has resulted in the need to provide new combinations in Dichanthelium for four species previously assigned to Panicum: P. bicknellii Nash, P. filiramum Ashe, P. malacon Nash, and P. pinetorum Swallen. The four species have either been treated as synonyms of other Dichanthelium taxa in recent manuals and monographs, or not treated at all. The new combinations are: Dichanthelium bicknellii (Nash) LeBlond, D. filiramum (Ashe) LeBlond, D. malacon (Nash) LeBlond, and D. pinetorum (Swallen) LeBlond. [ABSTRACT FROM AUTHOR]
