P. Auhurne Ashe, the two former at Grand Beach in the extreme 

 southwest corner of Michigan, and the last at Dune Park, Ind. 

 Panicum microcarpon, found in 1913, grew in deeply shaded rather 

 wet woods by State Line Creek, and appears to be unrecorded 

 for the flora of Michigan. The time being early September the 

 stems were much branched, weak and prostrate. P. Auhurne, 

 found also in 191 3, is set off from others with which it was asso- 

 ciated by its gray look, due to its silky hairs and velvety pubes- 

 cence. It grew in the sands of oak and pine woods which 

 characterize the dunes. This species, as well as P. Alhemarlense 

 Ashe, and P. verrucosum Muhl., both likewise of the dune region, 

 are of especial interest as representatives of the Atlantic coast 

 flora far removed from their general range. 



Panicum clandestinum L. is somewhat peculiar in its range in 

 the region as far as I can learn. It occurs in Indiana just south 

 of Michigan City, and again north of that place by State Line 

 Creek, a stream draining the ground that skirts the outer side 

 of the sand hills by Lake Michigan, and breaking through them 

 enters it at Grand Beach. In the bottomlands of this creek it 

 forms dense patches with stems 4 to 5 feet high. It follows down 

 the creek and is common along its banks at Grand Beach. 



Sporobolus brevifolius (Nutt.) Scribn. I first obtained this in 

 1906 from dry hills of Joliet gravel a little west of Joliet. It is a 

 representative of a flora whose range is north and west of this 

 region. It grows in dense tufts like a bunch grass. In 1912 I 

 came across it again a few miles west of this station by the banks 

 of the DuPage River. It was in a shallow soil covering the 

 limestone rocks that border the river. The layer of earth was so 

 thin that the roots and stolons passed through it and adhered 

 to the rock. This adhesion was so strong that efforts to pull up 

 the stems commonly resulted in breaking the culms instead of 

 detaching them from the rock, so that a knife was used to cut 

 away the sod. 



Poa dehilis Torr. Although I found this as long ago as 1890, 

 in the sandy woods at Casello, now within the limits of Indiana 

 Harbor, Ind., it does not seem to have been reported for this 

 region. I had not seen it since within our bounds till the summer
