Muhlenbergia torreyana
|
This range of the New Jersey muhly has significantly declined over the last century, but it is still found in four states, one of which is New Jersey, where the species is locally abundant in the Pine Barrens. (NatureServe 2001).
A true grass, M. torreyana produces a plume of purple flowers that can be up to a foot in length that is held on a 12” to 30” stem.
