New species of Uredineae — III, 
J. C. ARTHUR 
The following sixteen species of rusts have been detected 
among material sent for identification, in large part submitted by 
Professor F. S. Earle, curator of fungi of the New York Botanical 
Garden. I am also directly indebted for material to E. W. D. 
-Holway, C. V. Piper, J. M. Bates and E. Bartholomew and indirectly 
to Messrs. Heller, Baker, Tracy, Goodding, Craig, Underwood 
and Griggs. Two thirds of the species are trans-Mississippian, 
and the remainder from Porto Rico. It is worthy of special note 
that, with the exception possibly of four species at the most, the 
descriptions here given are incomplete, as they include but one or 
two out of the possible three, four, or even more spore-forms. It 
should be the endeavor of those botanists, who are privileged to 
collect in the regions where these species abound, to secure the 
remaining spore-forms in order that the descriptions may be com- 
pleted.
