who thought it might be a new species and drew up a descrip- 

 tion. Not long afterward Mr. Ellis sent his notes and material 

 to Dr. Rostrup, of Copenhagen, Denmark, who pronounced it to 

 be P. tenuistipes Rostr., by which name it has since been called.* 



3. Puccinia Caricis (Schum.) Reb. Teliosporic material 

 on Carex stipata Muhl. from the vicinity of Lafayette, Ind., 

 brought in by Mr. Frank Vasku, was sown on Urtica gracilis 

 April 19, giving rise to pycnia April 27, and aecia May 2; 

 while a similar collection brought in by Mr. F. D. Kern, and 

 sown April 20, gave rise to pycnia April 27, and aecia May 1. 



Teliosporic material on Carex riparia Curt., collected in 

 November, 1906, at Scotia Junction, Neb., by Rev. J. M. Bates, 

 was sown April 13, on Ribes Horidum and R. rubrum, with no 

 infection. Another sowing was made April 19 on Urtica 

 gracilis, giving rise to abundant pycnia April 26, and aecia 

 May 1. A second collection from the same region, taken in 

 March, 1907, was sown April 4 on Ribes Horidum, with no in- 

 fection; and again April 19, on Urtica gracilis, giving rise, as 

 in the former case, to abundant pycnia April 26, and aecia May 2. 

 Similar material on Carex riparia from Iowa gave the same re- 

 sults in 1902. 10 



4. Puccinia angustata Peck. Teliosporic material on 

 Scirpus atromrens Muhl., from the vicinity of Lafayette, Ind., 

 brought in by Mr. Frank Vasku, was sown on Lycopus Ameri- 

 canus April 22, giving rise to pycnia April 29, and aecia May 7. 11 



5. Puccinia fraxinata (Schw.) Arth. A collection 

 made in November, 1906, on Spartina cynosurcides Willd., at 

 Red Cloud, Neb., by Rev. J. M. Bates, was sown on Fraxinus 

 lanceolata May 11, giving rise to pycnia May 18. The same 

 collector sent similar material from Grand Island, Neb., in 

 March, 1907, which was sown on Fraxinus lanceolata May 25, 

 giving rise to pycnia May 30, and aecia June 13. A like col- 

 lection taken in April, 1907, similarly sown May 8, gave pycnia 

 May 17. These sowings were all made on cut branches placed 

 in water, which accounts for the slow development and early 

 termination of growth. 12
