232 Lake Maxinkuckee, Physical and Biological Survey 



borne in a loosely spreading, drooping panicle. Common in the 

 low wet woods along the south shore of the lake, by Overmyer's. 

 Found in flower about the middle of June. 



85. RED-TOP 



ARGOSTIS ALBA L. 



One of the most handsome and valuable of our grasses, usually 

 growing in scattered patches among sedges and wild grasses of 

 various species and forming in places the most valuable part of 

 "prairie-hay." This species is not very common about the lake. A 

 few patches, however, were seen in the prairie country west of the 

 lake, and a few specimens were obtained at the edge of Green's 

 woods by Lost Lake. Where there are unbroken patches it turns 

 the whole area occupied a purplish red which shows for consider- 

 able distances. 



86. THIN-GRASS; UPLAND BENT-GRASS 



AGROSTIS PERENNANS (Walt.) Tuckerm. 



A rather inconspicuous, but handsome symmetrical grass. Not 

 rare at the lake, but scattered. Most frequently seen along shady 

 woodland paths. 



87. ROUGH HAIR-GRASS 



AGROSTIS HYEMALIS (Wait.) B. S. P. 



A very thin inconspicuous grass, common through dry wood- 

 lands. It quite closely resembles the preceding. It was plenti- 

 fully scattered through Green's woods by Lost Lake, and was also 

 noticed and collected southwest of the lake. It is too small and 

 scanty to be of any value for pasture. 



88. BLUE-JOINT GRASS 



CALAMAGROSTIS CANADENSIS (Michx.) Beauv. 



This grass is fairly common in the low flats mixed in with other 

 grasses and with sedges, its tall heads projecting considerably above 

 the tops of the sedges. It is not so abundant as at near Plymouth, 

 where it forms large continuous patches in places. It was scat- 

 tered in Green's marsh and in the sedgy marsh below Overmyer's. 

 It was quite abundant, mixed with sedges, far down the outlet, and 

 formed almost the entire flora of the center of a pond in Walley's 

 woods. It is one of the most valuable of the prairie grasses, and 

 where abundant enough, is cut for hay.
