Orton : Notes on Polemoniaceous Rusts

Ellis & Harkness' whose combined paper appeared immediately 

 preceding that of Harkness. The type was collected on leaves 

 and subtending bracts of Gilia ciliafa. Mt. Diablo, May. 2pp6. 



There appears to be no specimen in the Ellis collection and it 

 seems probable that Harkness did not send Ellis any of this mate- 

 rial. Prof. W. C. Blasdale has kindly visited the Herbarimm of 

 the California Academy and found one specimen which he takes 

 to be the type. He says in his letter to Prof. H. S. Jackson 

 (June 8, 1916) : " The specimen consists of a single head of Gilia 

 ciliata evidently collected after the plant had dried up." The 

 packet bore the following data: Puccmia Giliae Hk. Gilia, dead 

 stems, Antioch, June 17, 1882, <?pp(5. In commenting upon the 

 discrepancy between this data and the published account Prof. 

 Blasdale states further " although the published description gives 

 Mt. Diablo as the type locality I think this specimen represents the 

 type collection as Antioch is near the base of Mt. Diablo and 

 Harkness was decidedly inaccurate in his data relating to his col- 

 lections. The specimen bears a half dozen sori on the floral 

 bracts." 



My examination of a portion of this material sent by Prof. 

 Blasdale shows smooth spores much thickened above (7-13 /x) 

 and measuring 18-28X40-60^0, with pedicel up to lOO/x, rather 

 persistent. It has been impossible to make a careful search for 

 urediniospores with the limited material at hand, but in the one 

 mount made a few appeared which seemed to correspond in 

 every way with the rust which appears on several species of 

 Gilia in California and adjacent states which when collected 

 early bears abundant uredinia. The presence of urediniospores 

 and the smooth teliospores conspicuously thickened at the apex 

 makes this rust distinct from any others known on these hosts. 

 It is known at present only from the Rocky Mountain region and 

 the Pacific Coast.

The type of this rust collected by Dr. Macoun and described 

 as forming aecia and telia on Arabis sp., Ottawa. Canada, is in

 Sci. I : 26-29. 1884.
