 Valley to s. Ind. 



80. Carex laxiflora Lam. (Carex heterosperma Wahl., Carex anceps 

 Muhl. and Carex laxiflora var. patulifolia (Dewey) Carey.) (Including 

 Carex striatula Michx., Carex laxiflora var. striatula (Michx.) Carey, and 

 "Carex laxiflora" Mack., not Lam., in Small, Manual of the Southeastern 

 Flora.) Map 504. Common in dry woods, especially beech-sugar maple, 

 throughout the state. 



The form commonly referred to Carex striatula Michx. may deserve 

 varietal recognition, at least in the southern part of its range and on the 

 Coastal Plain where it attains the extreme of its differentiation, but in 

 Indiana intermediates so far outnumber the extremes that all attempts 

 to separate it even varietally have been unsuccessful. 



N. S. to Mich., southw. to Fla. and Tex. 



80a. Carex laxiflora var. serrulata Hermann. (Rhodora 40: 80. 1938.) 

 Map 505. Known from four counties all in the eastern half of the 

 state. Its habitat is that of the species. The type collection (Deam no. 

 6458) came from a wooded ravine two miles northwest of Henry ville, 

 Clark County, May 25, 1910.

81. Carex albursina Sheldon. (Carex laxiflora var. latifolia Boott.) 

 Map 506. Common on wooded slopes, chiefly in limestone areas; rare in 

 low, moist or alluvial woods. 



Deam's collection of May 7, 1905, from Blackford County is exceptional 

 in having the leaves semi-evergreen and rather rigid. 

 Que. to Minn., southw. to Va. and Ark. 



82. Carex blanda Dewey. (Carex laxiflora var. varians of authors, not 

 Bailey.) Map 507. Very common throughout the state, doubtless occurring 

 in every county. In woods of all types it is the commonest species of this 

 section of the genus. The other Indiana species of the C. laxiflora group
