Carex Cyperaceae 275 



20. Carex formosa Dewey. Reported from Putnam County by Grimes. 

 The specimen upon which this report was based (Grimes no. 540, in 

 DePauw University Herbarium) is C. Davisii. In Coulter's Catalogue 

 also C. formosa is reported from Putnam County and the record ascribed 

 to MacDougal. The collection which formed the basis of this report, too, 

 should doubtless be referred to some other species. 



Que. to Wis., southw. to Conn, and N. Y. ; very local. 



21. Carex arctata Boott. Bradner reported this species from Steuben 

 County but no specimen could be found so it must be excluded. It is known 

 in Ohio and in southwestern Michigan (Kalamazoo County; reported also 

 from Berrien County) so that it is quite possible that it is, or was, native 

 in dry rich woods in northern Indiana. 



Newf. to Minn., southw. to Pa. and Ohio. 



22. Carex pallescens L. Both Pepoon and Peattie report this species 

 from Lake County, basing the reports on a record by Hill from Berry 

 Lake. No specimens have been seen. Smith's report from Marion County 

 and Schneck's from the Lower Wabash Valley unquestionably must have 

 been based upon misidentifications, and the occurrence of the species even 

 in northernmost Indiana is very doubtful. 



Newf. to Wis., southw. to N. J., Pa., and 111. ; also in Eurasia. 



23. Carex scabrata Schwein. Reported from Lake County by Higley & 

 Raddin and by Peattie but no Indiana specimens could be found. 



N. S. to Ont. and Mich., southw. mostly in the mts. to S. C. and Tenn. 



24. Carex paupercula Michx. A northern species reported from Pine, 

 Lake County, by Peattie and by Pepoon (as C. paupercula var. irrigua 

 (Wahl.) Fern.) who ascribe the record to Hill. In all probability collec- 

 tions upon which these reports were based, but which could not be found 

 should be referred to C. limosa. 



Newf. to Alaska, southw. to Pa., Minn., Colo., and Utah; also in n. 

 Eurasia. 



25. Carex aquatilis Wahl. A far northern and western species which 

 has been reported from Lake, Porter, La Porte, and Marion Counties. All 

 material forming the basis of Indiana reports should be referred to other 

 species. C. aquatilis of most manuals for this area is C. substricta 

 (Kiikenth.) Mack. 



Greenland to Alaska, southw. to Que. and in the w. mts. to N. Mex. 

 and Calif. ; also in n. Eurasia. 



26. Carex nebraskensis Dewey. This western sedge has been reported 

 from' Fayette, Jefferson, and Tippecanoe Counties by H. S. Jackson, ap- 

 parently through the misapplication of a synonym. He lists it as the 

 host of a rust and cites for it a correct synonym, Carex Jamesii Torr. 

 But Prof. Arthur states that the rust occurs on Carex Jamesii Schwein., 

 and without doubt that is the species that Jackson had. 



S. Dak. and Kans. to N. Mex., Calif., and B. C.
