New species of Uredineae — V 



Joseph Charles Arthur 



The following new species are presented as the result in part 

 of critical study of general herbarium material and in part of recent 

 collections kindly sent by the collectors or otherwise communi- 

 cated. For the new material I am indebted to Messrs. E. W. D. 

 Holway, P. H. Rolfs, C. F. Baker and Ernst A. Bessey, and ex- 

 tend hearty thanks for the same. The species come from various 

 parts of western Canada, western and southern United States, 

 Mexico and the West Indies. The assortment of species is more 

 than usually interesting, as it embraces some belonging to little- 

 known genera, and some that clarify knowledge of common 

 forms. 



In the preceding number of this series occur two errors needing 

 correction. Pttccinia Dolichi (Bull. Torrey Club 33: 28) is an 

 unwarranted name. Only the uredinia of the description belong 

 to the species, the teliospores being yet unknown ; but as the rust 

 is on a leguminous host, they are more likely when found to belong 

 to Uromyces than to Puccinia. The teliospores of the description, 

 as pointed out recently by the collector, were stray spores from 

 some Mexican euphorbiaceous plant transferred to the Cuban 

 specimens by means of the drying papers. Until the teliospores 

 are discovered it might be well to call the Cuban rust on Dolichos, 



Uredo Dolichi. 



The second error is orthographical, and requires the substitu- 

 tion of o in place of a in the new generic name (Joe. cit. page 30),
