In<, was sown on the same host and on Cicuta metadata, with no 

 infection. Last year this rust was sown on two other species of 

 Polygonum without infection. Recently the preliminary an- 

 nouncement of rust cultures for the season of 1903 by Dr. W. 

 Tranzschel of St. Petersburg has been published. He states 

 that infection was secured on Geranium, showing that the widely 

 distributed Aecidium sanguinolentum Lindl., commonly found on 

 Geranium maculatum in America, is the alternate form of this 

 rust. My own observations in the field all go to affirm the cor- 

 rectness of this result. 



3. Puccini a on Car ex Pennsylvanica Lam. from Red Cloud, 

 Neb., and Fair Oaks, Ind., was sown on Aster panicnlatus, A. 

 Drummondii, A. prenanthoides, Solidago rigida, S. canadensis, 

 Xanthium Canadcnse, Silphium perfoliatum, Ribes Cynosbati, R. 

 aureum, Geranium maculatum, Viola cucullata, and Onagra bien- 

 nis, with no infection. 



4. Puccinia on Car ex gravida Bailey from Red Cloud, 

 Neb., was sown on Aster Drummondii, A. panicnlatus, Senecio 

 oboratus, Boltonia asteroides, Silphium perfoliatum, Ambrosia 

 tritida, Xanthium Canadense, Cleome spinosa, Sambucus Cana- 

 densis, Ribes Cynosbati, Xanthoxylum Americanum, and Onagra 

 biennis, with no infection. 



5. Puccinia on Elymus Canadensis L. from Red Cloud, 

 Neb., was sown on I mpatiens aurea, Symphoricarpos racemosus, 

 and Napaea dioica, with no infection. There are various reasons, 

 of which the above is one, for thinking that the rust on the 

 several species of Elymus, occurring east of the Rocky Mts., 

 which has heretofore been referred to one species really belongs 

 to several species. 



6. Puccinia vexans Farl. on Bouteloua curtipendula 

 (Michx.) Torr. from Red Cloud, Neb., was sown on Cleome 

 spinosa, P4iysalis heterophylla, Physalodes Physalodes, Cassia 

 Chamaeerista, and Paitstemon hirsutus, with no infection. 



7. Puccinia tosta Arth. on Sporobolus neglectus Nash 

 from Red Cloud, Neb., was sown on Oxalis cymosa, Ceanot/ius 

 Amcricaiuts, Symphoricarpos racemosus, Cassia Chamaeerista, 

 Callirrhoe uivoluerata, Xanthoxylum Americanum, Cleome Spi- 

 nost, and Aster ericoides, with no infection. 



8. Puccinia emaculata Schw. on Panicum capillar e L. 

 from Fair Oaks, Ind., was sown on Aster prenanthoides, A. 

 Drummondii, Solidago rigida, Lactuca Canadensis, Eupatorium 

 perfoliatum, Xanthium Camdense, Ambrosia triiida Apocynum 

 eanuabinuux, Polemonium reptans, Ribes Cynosbati, Onagra bien- 

 nis, Anemone Pennsylvanica, and Geranium maculatum, with no 

 infection.
