128 Karl M. Wiegand and Arthur J. Eames 



Lab. and Newf. to Minn., southw. to Conn., N. Y., and Mich., and in the mts. to

 Leaves more fluted than in C. anceps.

 reous soils ; frequent. June-July. 



Inlet Valley, s. of Enfield Creek; railroad s. of Buttermilk Creek; Six Mile 

 Creek (D. !) ; Cascadilla Glen (D.) ; Freeville and the McLean region; Taughan- 

 nock Gorge ; Paine Creek ; Junius marl ponds ; n. of Spring Lake ; Westbury Bog ; 

 and elsewhere. 



Newf. to B. C, southw. to n. Conn., Pa., Ind., Wis., Utah, and Calif. ; rare or 

 absent on the Atlantic Coastal Plain. 



80. C. Woodii Dewey. (C. colorata Mackenzie, Bui. Torr. Bot. Club 37:232. 1910. 



C. tc tanica of Cayuga Fl., in part.)

81. C. tetanica Schk. 



Marl springs and meadows ; scarce. June 10-30. 



Spring, Inlet Valley s. of Enfield Creek; Junius marl ponds (D. !) ; prairie n. of 

 Crusoe Lake. Dudley gives some other stations, but whether these refer to this 

 species or to C. Woodii is uncertain. 



Mass. to Man., southw. to D. C. and Mo. ; rare on the Coastal Plain. 



The differences between C. tetanica and C. Woodii are fairly constant, but they 

 are almost entirely in connection with the lower part of the plant, and might be sus- 

 pected to be due to the radically different type of soil which each inhabits although 

 this does not seem to be the case. Without structural characters in the inflorescence, 

 the separation of these two species by the characters given is not very secure.
