3. Glyceria canadensis (Michx.) Trin. (Panicularia canadensis 

 (Michx.) Ktze.) Canada Mannagrass. Map 141. Infrequent in the lake 

 area where it is found in wet habitats in marshes, ditches, and springy 

 places and about ponds. 



Newf. to Minn., southw. to Md. and 111. 



4. Glyceria pallida (Torr.) Trin. (Panicularia pallida (Torr.) Ktze.) 

 Pale Mannagrass. Map 142. This grass has been found infrequently in 

 a few of our northern counties. It grows in a very wet habitat, usually 

 in shallow water or in ponds that dry up in midsummer. 



Maine to Wis., southw. to N. C. and Mo. 



5. Glyceria borealis (Nash) Batchelder. (Panicularia borealis Nash.) 

 Northern Mannagrass. Map 143. This plant is doubtless very rare in 

 Indiana. The habitat is the same as that of the preceding species. 



Newf. to Alaska, southw. to Conn., Ind., Iowa, S. Dak., and in the mts. 

 to N. Mex. and Calif.
