SOME CALIFORNIAN UREDINE^. 



By E. W. D. Holway. 



A PRELIMINARY list of the Uredinese of California recently made 

 shows in Puccinia, 122 species; in Uromyces, 42 species; and of other 

 genera, 73 species. This is a very large number when it is remem- 

 bered that only a small part of the state has been explored. In 

 compiling the list I found the following new species in my her- 

 barium. They were submitted to Dr. Dietel, who sent me descrip- 

 tions in German : — 



Puccinia Palmeri (Anderson), Dietel and Holway. ^cidial 



8ta,ge = jEcidium Palmeri Anderson. Teleutospore-sori intermixed 

 with the aecidia, small to medium size, at first covered by the 

 epidermis, prominent, at length naked, dark brown ; teleutospores 

 oblong or elliptical, distinctly constricted, rounded at both ends, 

 apex not at all or slightly thickened, often with a small papilla. 

 31-40x20-26//.; epispore smooth, brown; pedicel short, fragile. 

 Oq penstemon confertus, Lake Tahoe, July, 1897, W. C. Blasdale. 



Uredo Gaillardiae, Dietel and Holway. Sori scattered over 

 nearly the entire under surface of the leaf, and sparingly on the 

 upper, small, naked, dark brown ; spores brown, obovate to globose 

 30—35x24-31//. ; epispore thick, with short spines. 



On Gaillardia aristata, Sisson, May, 1894, Holway. 



iCcidium pseudo-^balsameum, Dietel and Holway. Pseudo- 

 peridia in two rows, on the under side of the leaves, opening irregu- 

 larly, composed of cells 40-50/Jt long, and 25-30/.^ broad, very 

 coarsely tuberculate ; spores globose to oblong, 23-28xl9-21/i ; 

 epispore strongly tuberculate. 



On Abies grandis, Eureka, June 4, 1896, W. C. Blasdale. 



In habit and appearance of the spores, this species is much like 

 Peridermium balsameum, Pk., but is readily distinguished by the 

 extremely large warts of the peridial cells, those of Peridermium 

 balsameum being quite small. 



>Ecidium Triglochinis, Dietel and Holway. iEcidia on all 

 parts of the plant in irregular groups ; on the stems often linear, 

 and with spermagonia ; pseudoperidia cylindrical on the pedicels, 

 and almost hemispherical on the stems and leaves; spores poly- 

 gonal or almost globose, 17-28x14-18/^, with a thin, finely 

 tuberculate epispore. 



On Triglochin concinna, Amedee, June 10, 1897, J. B. Davy.
