Chasmanthium

Chasmanthium is a genus of North American plants in the grass family.[4][5]

Members of the genus are commonly known as woodoats.[6] One species, Chasmanthium latifolium, is commonly cultivated.[4]

The generic name is derived from the Greek words χάσμα (chasma), meaning “wide opening,” and ἀνθός (anthos), meaning “flower.”[7]
