Ecology & Natural History

Habitat: Species is distributed on sandy woodlands, usually in open woods of deciduous or pine trees, sandstone or more commonly cherty limestone glades; openings above limestone escarpments, and along roads.

ILPIN Notes: This is one of the last species to flower in Illinois. The longer scabrous lemma, the long panicle and absence of rhizomes distinguish this delicate, open-panicled grass from M. asperifolia. Also, there are very long awns on lemmas. According to Ref. 4, this is "...a handsome grass with graceful rosy-purple panicle of hairlike branches and pedicels." Species is only found in the southern counties. Species is caespitose. Species is difficult to transplant and to establish in a wild garden.
