95-282. CYNODON Richard 



1. Cynodon Dactylon (L.) Pers. (Capriola Dactylon (L.) Ktze. Ber- 

 muda Grass. Map 253. This grass has become sparingly established in 

 the state and I predict that in time it will become a grass used frequently 

 for lawns and pasturage. It thrives well in sandy soil where bluegrass 

 will not. 



In a waste, vacant lot in Bluffton, Wells County, two large colonies 

 have been established for several years and these were not injured by a 

 temperature of twenty-one degrees below zero of the winter of 1935-1936. 



Introduced in America, and found in the warm regions of both hemi- 

 spheres. Md. to Okla., southw. to Fla., Tex., and Calif. ; occasionally northw. 

 from N. H. to Mich, and Oreg.

1. Spartina pectinata Link. (Spartina MicJiauxiana Hitchc.) Prairie 

 Cordgrass. Map 254. This species is infrequent or rarely frequent and 

 seems to be restricted to the lake and prairie areas and to the slope of the 

 bank of the Ohio River, usually in crevices of shale. In the lake area, it is 

 found on the low borders of lakes and streams and in marshy places. In 

 the prairie area, it is found in wet places, usually closely associated with 

 Calamagrostis canadensis.

101-290. GYMNOPOGON Beauv. 



1. Gymnopogon ambiguus (Michx.) BSP. Map 255. On September 19, 

 1934, I found a large colony of this species in very sandy soil on the crest 

 of a sand ridge in an open place in a woods in sec. 35 about 5 miles north-
