Blasdale: Uredinales of California 119 



53. Puccinia Epicampis Arthur. II, III 



Bull. Torr. Bot. Club, vol. 33, p. 662, 1901. 

 On Epicampes ring ens Benth., San Diego (Bethel). 



54. Puccinia Fendleri (Tracy and Earle) Jackson. I, III 



Mem. Brooklyn Bot. Gard., vol. 1, p. 246, 1918. 



Aecia (Aeciddum Fendleri Tracy and Earle) on Berberis pinnata 

 Lag., Berkeley. Collected but once and but poorly developed. This 

 was formerly taken to be the aecial stage of Uropyxis sanguinea 

 (Erythea, vol. 3, p. 131, 1895) and its specific identity is still an open 

 question. 



Telia not reported from California but to be expected on species of 

 Koeleria. 



55. Puccinia glumarum (Schmidt) Erikss. and Henn. II, III 



Zeitschr. f. Pflanzenkr., vol. 4, p. 1917, 1894. 



On Hordeum murinum L., near Tehachipi (A. G. Johnson). This 

 is one of the most destructive grain rusts in Europe but apparently 

 it is not common in California. See Humphrey and Johnson, Phyto- 

 path., vol. 6, p. 80, 1916. 



56. Puccinia graminella (Spez.) Diet, and Holw. I, III 



Erythea, vol. 3, p. 80, 1895. 



On Stipa eminens Cav., Berkeley. This is the only rust which 

 produces its aecia on a grass; the aecia are easily overlooked. 



57. Puccinia Holcina Erikss. II, III 



Ann. Sci. Nat., ser. 8, vol. 9, p. 274, 1899. 



Uredinia on Notholcus lanatus (L) Nash, extremely common in 

 the bay region, Humboldt County, southern California (Bethel)..

Pk. Bull. Torr. Bot. Club, vol. 29, p. 74, 1883.
