Somes Stream, Somesville (Rand). 

 G. fluitans (L.), R. Br.

PUCCINELLIA, Parl.* (Atropis, Rupr.) 



P. maritima (Huds.), Parl. Atropis maritima (Huds.), Griseb'. 



Glyceria maritima (Huds.), Wahl. SEA SPEAR GRASS. 

 Rare. Shore. Somes Harbor (Redfield). A puzzling form, 

 perhaps a hybrid between this species and P. distans, Norwood 

 Cove (M. L. Fernald). 



Var. (?) minor, S. Watson. Atropis maritima, var. Nutkaensis 

 (Presl), Scribner. Atropis angustata (R. Br.), Griseb. 

 Puccinellia angustata (R. Br.). Glyceria angustata (R. 

 Br.), Fries. 



Sea beaches. Somesville; Ovens; Thomas Bay; Southwest 

 Harbor; Mt. Desert Narrows, and elsewhere. " This form is 

 distinguished from P. maritimaby its smaller and weaker habit, 

 and by having the keels of the palea smooth below and only very 

 minutely scabrous above. In P. maritima the keels of the palea 

 are strongly fringed nearly or quite to the base." F. Lamson- 

 Scribner. More recent examination shows this form to be spe- 

 cifically distinct, and should bear the name in the Manual of 

 P. angustata (R. Br.). 



PESTUCA, L. FESCUE GRASS. 



F. ovina, L. SHEEP'S FESCUE. 



Common especially on or near the shore. Also on Cranberry 

 Isles. All specimens from Mt. Desert and vicinity are referred, 

 however, to F. rubra, L., by Prof. F. Lamson-Scribner, which 



* Better considered as a sub-genus of Glyceria.
