 Carex normalis Mack. 



late scales are relatively longer, acuminate to acute or occasionally blunt; 

 in C. cristatelki the scales are shorter, with dilated hyaline blunt tips. 

 Umbach no. 3651 and Bebb nos. 541 and 874, all from Lake County, are 

 intermediate between C. Bebbii and C. cristatella in most of their char- 

 acters. Similar material from Michigan has been identified by Mackenzie 

 as a hybrid between the two species.

37. Carex tenera Dewey. (Carex straminea of recent authors, not 

 Willd. ; Carex tenera var. echinodes (Fern.) Wieg.) Map 458. Frequent 

 in or near the lake area and in the southern counties in dry or moist, 

 usually open, woods, on borders of ponds in woods, and along railroad 

 ditches. Generally the heads are fewer-flowered in this sedge than in other 

 species of § Ovales and this condition and the widely spreading perigynia 

 sometimes result in a superficial resemblance to species of § Stellulatae.

38. Carex normalis Mack. (Carex mirabilis Dewey, not Host.) Map 

 459. Very common in dry or moist woods and thickets. In the eastern 

 part of its range this species seems to be partial to dry open habitats, but 

 in Indiana it has been most often collected in low or flat woods, shaded 

 ravines, marshy habitats on the borders of ponds, and on the flood plains 

 of streams.

39. Carex festucacea Schkuhr. (Bull. Torrey Bot. Club 42: 608. 1915.) 

 Map 460. Frequent in southern Indiana in low flat woods, especially pin 

 oak woods, and on moist wooded slopes; occasional in roadside and rail- 

 road ditches in the northern counties.
