Comments: Deer tongue is one of New Jersey’s most common and identifiable rosette panic grasses. It is one of the Flora’s largest species, reaching 3/4 of a meter tall with large, broad dark grren cauline leaves. The plant can be confused with Dichanthelium latifolium and D. boscii, but stem (stiff hair), leaf (>10 cm) and size (up to 1 m) characters should distinguish deer tongue from the two other more diminutive woodland species. Deer tongue can be found in old fields, roadsdies, abandoned farm yards and similar disturbed habitat. When present, it often forms a dense near monotypic colony, something that is difficult to overlook.
