178 FLORA OF MOUNT DESERT. 



Var. VULGABIS (With.), Thurb. RED- TOP. 



Meadows and fields; common. Naturalized from Europe 

 through cultivation, and perhaps also indigenous. 



A. perennans (Walt.), Tuck. 



Frequent in damp shady places and by brooksides. Beech 

 Mt. Notch; Deer Brook, Jordan Pond ; Gilmore Brook; Little 

 Harbor Brook Notch, and elsewhere (Rand); Southwest Harbor 

 (M. L. Fernald). It seems doubtful whether these northern plants 

 belong to the true southern A. perennans. A form from woods 

 south of Beech Mt. may be A. Novce-Anglice, Tuck. 



A. scabra, Willd. HAIR GRASS. 



Dry soil; common. A dwarf form growing in tufts in rock 

 hollows and dry places is var. montanum (Torr.). Sargent 

 Mt. (Greenleaf, Band) ; Western Mt. ; White Beach, Great 

 Pond (Rand). 



A. canina, L. 



Infrequent. Sargent Mt. (Greenleaf, Rand). 



CINNA, L. WOOD REED GRASS. 

 C. pendula, Trin. 



Damp woods. Cold Brook ; Little Harbor Brook valley; 

 Beech Mt. Notch (Rand) ; Seal Harbor (Redfield). A very 

 robust form, head of Beech Mt. Notch (Rand). 



CALAMAGROSTIS, Adans. REED BENT GRASS. 



C. Canadensis (Mx.), Beauv. BLUE JOINT. 



Common in moist or wet ground from sea level to mountain 

 summits. 



DESCHAMPSIA, Beauv. HAIR GRASS. 



D. flexuosa (L.), Trin. 



Common in dry places, especially on hills and mountains.
