Minuus (L.) Pers., E. philadelphicus L., and Leptiloii canadense (L.) 

 Britt., with the most unqualified success. The work of last year^ 

 is thus confirmed, and additional hosts ascertained. 



7. PucciNiA Caricis (Schum.) Reb. — A collection of this rust 

 on Carex stricta Lam., sent by Rev. J. M. Bates from Callaway, 

 Nebraska, gave rise to aecidia when sown on Urtic a gracilis Ait., 

 the dates for sowing, appearance of spermogonia and aecidia 

 being respectively May 24, June 2 and 7. The experimental 

 proof of this connection has been reported '"^ twice previously for 

 American material. A collection sent by Mr. E. W. D. Holway 

 from Decorah, Iowa, on Carex riparia Curt, was sown on Ribes 

 Cynosbati, R, gracile, R. aureum, R. floridum, and R, Uva-crispa, 

 Geranium macidatum^ 0?tagra bieimis^ Sambucus canadensis, and 

 Xanthium ca7iadense^ with no infection. It was sown on Urtica 

 gracilis May 21, and gave spermogonia May 27, and aecidia 

 June 2. 



8. PucciniaVilfae A. & H.— The alternate form of this rust 

 has been shown" to be Aeciditim verbenicola K. & S. These 

 results have been verified this season by sowing teleutospores 

 from Sporobolus longifolius (Torr.) Wood, collected at Callaway 

 Nebraska, by Rev. J. M. Bates, on Verbena stricta Vent, (culture 

 dates May 28, June 3 and 10) and on V, urticifolia L. (culture 

 dates the same), A collection from Lafayette, Indiana, on the 

 same host, was also sown on F. urticifolia with success (culture 

 dates May 2, 10, and ig). To conform to present knowledge 

 the name of the rust should be written Puccinia verbenicola (K, 

 & S.), nom. nov. 



g. Puccinia Windsoriae Schw. — A collection of the teleuto- 

 spores of this species of rust on Tricuspis seslerioides Torr. [Trtodia 

 cuprea Jacq.) was sent from Denton, Texas, by Mr. W. H. Long 

 Jr., with the statement that ^cidium Pteleae B. & C, which has 

 been taken to be the alternate form of the rust," had not been 

 observed in that vicinity. This material was sown on Ptelea in- 

 foliata L., May g, and spermogonia appeared May 15, followed 

 by abundant aecidia May 24.
