Oryzopsis asperifolia Michx 



County for 40 years and I have not found it, possibly because woods in 

 which it grew are now cultivated fields. 

 Newf. to Minn., southw. to Ga. and Okla. 



81-213. MILIUM L. 



1. Milium effusum L. Map 236. This species is very local and is found 

 in peaty woods with soft maple or in mucky or springy places with skunk 

 cabbage. 



N. C, Que. to Minn., southw. to Md. and 111. ; also in Eurasia. 



82-210. ORYZOPSIS Michx. Ricegrass 

 Blades narrow, involute; spikelets (exclusive of awns) less than 5 mm long; awns not 



more than 2 mm long l.O. pungens. 



Blades broad, flat; spikelets (exclusive of awns) more than 5 mm long. 



Leaves mostly basal; blades of culm generally less than 2 cm long, scabrous above. 



2. O. asperifolia. 



Leaves scattered along the culm; blades of culm more than 2 cm long, pubescent 

 above. 3. O. racemosa. 



1. Oryzopsis pungens (Torr.) Hitchc. Map 237. A few tufts of this 

 species have been found in Porter County over a limited area about a 

 quarter mile east of Waverly Beach in the Dunes State Park. This is the 

 only locality now known in Indiana. 



Lab. to B. C, southw. to Conn., Ind., S. Dak., and N. Mex. 



2. Oryzopsis asperifolia Michx. Map 238. This species is known only 

 from La Porte and Porter Counties where it is found on open wooded dunes. 



Newf., Man., B. C, southw. to Conn., Ind., S. Dak., and N. Mex. 



3. Oryzopsis racemosa (J. E. Smith) Ricker. Map 239. The specimens 

 found in the southern part of the state are from rocky woods and those 

 from the northern part are from moist or dry, sandy woods. It is very 

 local and I cannot account for its widely different habitats and limited 

 distribution. 



Que. to Minn., and S. Dak., southw. to Del., Ky., and Iowa.
