Carex gracillima Schweln. 



in dry beech, beech-maple, and white oak woods. Reported from Putnam 

 and Hamilton Counties by Wilson but no specimens could be found to 

 authenticate these reports. 



N. J. to Inch, southw. to Fla. and Tex. 



91. Carex grisea Wahl. Map 516. Very common throughout the 

 state in rich dry or moist woods and thickets, in ditches, on banks of 

 streams, and along roadsides. It is extremely variable in its vegetative 

 characteristics and in the shape and size of its perigynia. 



N. B. to Ont. and Minn., southw. to Ga. and Tex. 



92. Carex glaucodea Tuckerm. Map 517. Frequent in southern Indiana 

 on wooded or open hillsides in either dry or moist soils. It is partial to 

 slopes and ridges and its most frequent habitats are abandoned roads 

 in woods and paths on open grassy hills. No specimens could be located 

 to authenticate the reports from Lake County by Coulter and by Peattie. 

 All the known Indiana collections have come from within or very near 

 the unglaciated area.

25. § GRACILLIMAE 



Sheaths (except the lower which are dorsally somewhat hispidulous) and leaves 

 glabrous; perigynia less than 2 mm thick. 



Bracts long-sheathing; perigynia bluntly angled, obtuse at the apex 



93. C. gracillmia. 



Bracts sheathless; perigynia sharply angled, tapering into a triangular, often 



twisted, beak nearly as long as the body 94. C. prasina. 



Sheaths and often leaf blades pubescent; perigynia 2-2.5 mm thick 95. C. Davisii. 



93. Carex gracillima Schwein. Map 518. Doubtless found in every 

 county in the state. It is common in wooded ravines and in low woods of 

 all types, although it shows a preference for open beech or beech-maple 

 woods.
