Cenchrus purpurascens inflorescences M. R. Penskar inflorescences

An Asian species, sometimes cultivated as an ornamental and rarely escaped to disturbed banks and lawns in southwestern Michigan, where first collected by W. S. Martinus in Allegan Co. in 2007. A similar species, Cenchrus longisetus M. C. Johnst. (Pennisetum villosum Fresen.), is also regularly cultivated and may escape in southern Michigan. It differs in having the bristles plumose rather than merely scabrous. 

As noted by Chemisquy et al. (2010), Pennisetum should be united with Cenchrus; the correct name being C. purpurascens (Verloove, 2012).
