Carex cephaloldea Dewey 



Reported from Lake County by Peattie and by Pepoon but no authentic 

 specimens could be found. The Lake County reports were probably based 

 upon specimens of C. Muhlenbergii in the Field Museum and University of 

 Wisconsin herbaria which were collected by Umbach and distributed as 

 C. gravida. The report from Fayette County by Deam was based upon a 

 specimen of C. aggregata which was referred to C. gravida by Mackenzie. 



Deam no. 43219 is intermediate between C. gravida and its var. Lunel- 

 liana.

11a. Carex gravida var. Lunelliana (Mack.) Hermann. (Amer. Midland 

 Nat. 17: 855. 1936.) {Carex Lunelliana Mack. Bull. Torrey Bot. Club 42: 

 615. 1915.) Map 430. On sandy roadsides and railroad embankments in 

 the westernmost tier of counties where it is rare. Some of the Benton 

 County specimens intergrade slightly with the species but the Vigo County 

 plants from very sandy soil on a roadside knoll 5 miles north of Terre 

 Haute are a good match with the type material of C. Lunelliana.

12. Carex cephaloidea Dewey. Map 431. Rich woods. In Indiana known 

 only from two collections by Deam : beech-sugar maple woods a mile and 

 a half west of New Waverly, Cass County; and low woods bordering 

 Tippecanoe River north of DeLong, Fulton County. It is probably more 

 frequent than the few collections would indicate since it resembles the 

 ubiquitous C. sparganioides so closely that it is apt to be passed by as that 

 species. 



The Tippecanoe County report by Smith is not supported by a specimen 

 nor could any specimen be found to confirm Peattie's report from Lake 

 County. 



Specimens of C. alopecoidea (§ Vulpinae) before fully mature, and 

 particularly when from an open habitat, often closely simulate C. cepha- 

 loidea. These may be most readily distinguished by their acuminate to 

 cuspidate or aristate pistillate scales which are more than half the length
