Arthur: Uredinales of Costa Rica 113 



In 191 3 Mr. Ellsworth Bethel, of the State Museum, Denver, 

 Colo., paid a brief visit to Costa Rica and contributed two speci- 

 mens of rusts toward the present list. The collection of one rust 

 is also credited to H. Polakowsky. 



Aside from the above eighteen collections and one specimen 

 contributed by the Royal Herbarium, Kew, England, the material 

 which goes to make up the following account of the rusts of Costa 

 Rica was supplied by Professor E. W. D. Holway, of the Uni- 

 versity of Minnesota. Of the 118 species in the list all are rep- 

 resented among his collections, except three that are reported 

 solely by Sr. Tonduz. The 208 specimens in the Holway ma- 

 terial were obtained during a trip to Costa Rica in the winter of 

 191 5-16, made for the special purpose of collecting rusts. Pro- 

 fessor Holway is an experienced and able collector. His home 

 has been in Iowa and Minnesota, but he has traveled extensively 

 and has searched for rusts not only in the United States and 

 Canada, but also in various sections of Mexico, Guatemala, Pan- 

 ama and the West Indies. 



Professor Holway entered Costa Rica at Limon on December 

 9, 1915, and proceeded at once to San Jose. His first impressions 

 must have been of disappointment, judging from his brief letters 

 to the author. On December 10 he writes: "Arrived last night. 

 Costa Rica is too civilized, not near as interesting as Guatemala." 

 Three days later he says : " This country has climate, but not 

 much else — no Indians, no great native markets, absolutely no 

 native manufacture except a crude large jar made by hand en- 

 tirely. I mourn for Guatemala." Not only was he at first dis- 

 appointed as a traveler in the lack of strangeness and picturesque- 

 ness, but also as a collector because long, tiresome walks must be 

 taken to reach favorable surroundings for rusts. In the vicinity 

 of the larger cities " every inch is pastured or used for coffee, " 

 as he says, "and the wild plants have no place to stay." But if 

 his spirits at first were depressed by these unexpected evidences 

 of material advancement and prosperity, they rose later as he 

 became acquainted with the less conventional parts of the country. 

 On January 9, 1916, he writes: "I am just in from Volcan de 

 Poas. The ' rain-forest ' on the summit is magnificent. I never
