 Orton (Mem. N. Y. Bot. Gard. 6:177. 1916) is the authority for 

 the statement that this species has been cultured by Fromme. He sowed 

 aeciospores from primary aecia on the same host and obtained the 

 development of telia of the scattered type indicating that repeating 

 aecia do not occur in this species. An examination of specimens in the 

 Arthur herbarium has failed to reveal any collection of aecia not accom- 

 panied by pycnia.

Puccinia Cirsii-lanceolati Schroet. Pilze Schles. 1:317. 1887. 

 On Carduaceae: 



Cardmis lanceolatus L., Newark, October 1907, (2009). 

 This species produces aecia of a peculiar character having a rudi- 

 mentary aecidium. All stages occur most abundantly on the upper sur- 

 faces of the leaves. 



Kellerman (Jour. Myc. 9:229. 1903) has shown through carefully 

 conducted culture experiments that this species is an eu-Puccinia and 

 autoecious. In America it is known only on the above host.

 mons (302); Lewes, April 1908, I, (2260). 

 The collection by Commons was issued in E. & E. N. Am. Fungi 

 1857 as on Ipomoea panduruta (L.) Meyer. The host is certainly Con- 

 volvulus. Arthur (Bot. Gaz. 29:270. 1900) has shown that this species
