Arthur: Uredinales of Costa Rica 



123 



31. Uromyces decoratus Syd. (on Fabaceae) 



Crotalaria vitellma Ker., San Jose, Dec. 10, 191 5, II, 246; same, 

 Jan. 11, 1916, II, 410. 

 This long-cycle rust is now reported from America for the 

 first time, having been previously known only from the East 

 Indies. The uredinial sorus is applanate and nonparaphysate, 

 being quite unlike that of Phako psora Crotalariae (Diet.) Arth. 

 The Costa Rican material compares exactly with Sydow, Ure- 

 dineen 2-151, on C. juncea from India, the type collection, but 

 in the specimen seen showing only uredinia. Telia have not 

 been seen. There is an Uredo Theresae Neg. (Beih. Bot. Centr. 

 13: 78. 1902), from Colombia, S. A., which may be the same, 

 but no specimen has been seen and the description is inadequate 

 for decision. There is also an Aecidium crotalariicola P. Henn. 

 (Hedw. Beibl. 38: 70. 1899), from Brazil, which may possibly 

 have genetic connection with this species, but no sufficient present 

 information is available. 



32. Uromyces Indigoferae Diet. & Holw. (on Fabaceae) 



Indigo f era mucronata Spreng., Orotina, Dec. 30, 191 5, II, 322. 



A long-cycle rust, whose initial stage is not known. It extends 

 northward into Texas. 



33. Uromyces guatemalensis Vestergr. (on Fabaceae) 

 Bauhinia inermis Pers., Orotina, alt. 600 feet, Dec. 29, 191 5, ii, 



in, vs. 



A collection on the same host, as well as the type collection of 

 the species, with which this collection has been compared, came 

 from Guatemala. The rust is a long-cycle one, whose initial 

 stage is unknown. 



34. Uromyces Cologaniae Arth. (on Fabaceae) 



Cologania pulchella H.B.K., San Jose, Dec. 10, 191 5, II, 248. 

 Cologania sp., Road to Frai janes on Volcan de Poas, Jan. 6, 191 6, 



ii, 3S1. 



A long-cycle species reported from Mexico, Guatemala, and 

 Porto Rico. The initial stage in the life cycle is unknown.
