 Cyperus Torreyi Britton (C. cylindricuH (Ell.) Britton), Selby- 

 ville, Oct. 4, 1907, (1810). 

 Arthur (Jour. Myc. 12:23. 1906) conducted culture experiments in 

 1905 which showed that an aecidium on Xanthmm canadense is con- 

 nected with this species on various species of Cyperus. Following sow- 

 ings of aeciospores from X. canadense, collected in Indiana, uredinio- 

 spores developed on C. esculenttis.

On Carduace.\e: 



Chrysanthemum sinense Sabine, Camden, September 1905, 

 (1536); Wyoming, November 1907. 

 This rust causes considerable damage to cultivated chrysanthemums. 

 The life history is somewhat in doubt. In Ameiica the rust exists only 

 in the uredinial stage.

On Carduaceae: 



Cardials altissimus L., Faulkland, Oct. 20, 1886, A. Commons, 

 459; August 1887, A. Commons, 137. 

 The latter specimen was issued in E. & E. N. A. Fungi 2253 as 

 P. compositarum Schlecht, f. Cnici altissimi. This is a brachy-Puccinia 

 developing pycnia with the uredinia and occurs most commonly on the 

 under surface of the leaves. It occurs throughout the United States on 

 species of Carduus other than C. lanceolatus.
