| Poaceae | Cenchrus purpurascens | Chinese Fountaingrass, Foxtail Fountaingrass | Disturbed areas, roadsides, floodplains, old fields. | Native of e. Asia. This species seems to be developing into an invasive species, with increasing reports of its spread into natural areas, as opposed to merely occurring as a waif following cultivation. Reported for DE and MD, where frequently encountered on roadsides (Longbottom, Naczi, & Knapp 2016). |  |
| Poaceae | Cenchrus purpureus | Elephant Grass, Napier Grass | Swamps, wet grasslands, disturbed areas. | Native of Africa. Naturalized in FL north to the FL-GA border, and in AL (Diamond & Woods 2009). |  |
