 cated by N. Patouillard. 



9. Spirechina Rubi (Diet. & Holw.) Arth. (on Rosaceae) 

 Rubus trichomallus Schlecht., San Jose, Dec. 11, 1915, 11^ ii 2 , 



A very abundant species of Guatemala and Mexico, possessing 

 pycnia, uredinia and telia. 



10. Spirechina Loeseneriana (P. Henn.) Arth. (on Rosaceae) 



Rubus trichomallus Schlecht., above El Alto near Cartago, Jan. 

 16, 1916, II 15 III, 435. 

 A long-cycle species, similar to vS. Rubi, found chiefly in South 

 America, and heretofore only once reported for North America, 

 that being from Guatemala, collected in 1896. 



11. Spirechina Pittieriana (P. Henn.) Arth. (on Rosaceae) 



Rubus adenotrichos Schlecht., slopes of Irazu above Cartago, 



Dec. 23, 1915, O, 285. 

 Rubus sp., on road to Fraijanes, Volcan de Poas, Jan. 6, 1916, 



O, III, 380; San Jose, Jan. 8, 1916, O, II 1? III, 393. 

 This rust was first described as Uromyces Pittierianus P. 

 Henn., and at the same place (Hedw. Beibl. 41: 101. 1902) 

 the uredinia were called Uredo ochraceo-flavus P. Henn., both 

 names being founded on a collection by A. Tonduz, made at 

 Hacienda Belmira near Santa Maria de Dota, January 1898, on 

 Rubus sp., the host bearing the number 11615. Through the 

 kindness of I. Urban, of the Bot. Museum of Berlin, I have been 

 able to examine a portion of both types. By my suggestion Dr. 

 Urban secured the determination of the host, Dr. W. O. Focke 

 pronouncing it to be R. adenotrichos. 



12. Cronartium coleosporioides (Diet. & Holw.) Arth. (on 



Scrophulariaceae) 



Castilleja tenuiflora Benth. (?) Volcan de Irazu, Jan. 21, 1916, 

 II, iii, 452.
