digenous. The Island forms appear for the most part to be 

 indigenous northern and coast forms, and abound on beaches 

 and on banks by the shore. 



Var. glaucum (Desf. ), Boiss. Triticum repens, L., var. inter- 

 medium, Fries. 

 A glaucous, rigid, maritime form, with large crowded spikelets 

 and glumes blunt or mucronate. Seal Harbor (Redfield) ; — 

 Northeast Harbor; Southwest Harbor, etc. (Rand). 



Var. pilosum, Scribner. 



Upper surface of leaves pilose, rhachis of spike pubescent ♦'o 

 hirsute, flowering glumes awnless or short cuspidate pointed. 

 Southwest Harbor (Eand). This, however, may be the same 

 as var. agreste, Anders. 



Other well marked forms are numerous; but it seems impos- 

 sible to identify them with any certainty without a careful 

 comparison with authentic specimens in European herbaria. 



A. caninum (L.), Roem. & Schultes. Triticum caninum, L. 



Rare. Field near the head of Northeast Harbor (Rand). 

 Naturalized from Europe, and also indigenous. Probably intro- 

 duced on the Island.

ELYMUS, L. Wild Rye. Lyme Grass. 



E. Virginicus, L. 



Common on the coast.

 by many authors as identical with JS. arenarius, L., which 

 occurs on the Pacific coast.
