Found only in the north, where it occurs sparingly on the southern 

 shores of Lake Michigan. The mass distribution of the species is 

 near the sea coast. Contributed by Rev. E. J. Hill. 



Flowers in June. 



Lake (Hill). 



J. dichotomus Ell. Forked Rush. 



This species is admitted upon the authority of Dr. J. Schneck. I 

 have seen no specimens, but as the collections of Dr. Schneck were 

 passed upon by Dr. Gray, I do not feel justified in excluding the 

 species. The form is of dry soils ' ' near the coast " and its occurrence 

 in our southwestern counties is difficult to understand. 



Flowers in June. 



Gibson (Schneck). 



J. marginatum Rostk. Grass-leaved Rush.

 grassy, moist places along ditches and sluggish streams.
