On Cyperaceae: 



Carex nmbeUata Schk., beech woods, V2 mile S. W. Chestnut Ridge, 

 May 11, 191.3, C. C. Beam 127116. 



This species has a wide distribution in America as well as in other 

 parts of the world where Carex species are native. It should be found 

 on other host species in Indiana. The sori occur in the ovaries and 

 when mature are rather conspicuous subspherical bodies 3-4 mm. in 

 diameter. 



2. Cintractia Junci (Schw.) Trel. Bull. Torrey Club 12:70. 1885. 



Caeoma Junci Schw. Trans. Am. Phil. Soc. II. 4:290. 1832. 



On Juncaceae: 



Juncus diffusissimus Buckley, Versailles, Ripley County, .June 18, 

 1915, C. C. Deam 16087.

On Juncaceae: 



Juncoides campestre (L.) Kuntze, Greensburg, Decatur County, 

 May 10, 1889, J. C. Arthur; Terre Haute, Vigo County, May 12, 1917, 

 C. C. Deam 22959; Kramer, Warren County, May 18, 1917, C. C. Deam 

 23104; Salem, Washington County, C. C. Deam 23194. 



Previously known from North America only from the one collection 

 made in 1889 by Dr. Arthur at Greensburg, Ind. The sori are in the 

 ovaries but are inconspicuous and hence easily overlooked. The speciea 

 is doubtless of much wider distribution in this State than the above 

 collections would indicate.

37:79. 1896.
