Imperata cylindrica (L.) Raeusch. (ITIS)
Cogongrass, Cogon grass, Japanese bloodgrass, Red Baron grass
Imperata arundinacea, Lagurus cylindricus (ITIS)
In doubt: East Africa (Evans 1987, 1991); Southeastern Asia; (Holm et al. 1977)
First arrived accidentally in Louisiana in 1912, and it was introduced intentionally to Florida in the 1930s (Bryson and Carter 1993)
Used as packing material for imported goods (Tabor 1949); introduced intentionally as forage (Dozier et al. 1998) and for erosion control (Moorehead et al. 2007)
Forms dense stands that crowd out native species (Lippincott 1997)
