JACKSON: UREDINALES OF OREGON 275 



On Poaceae: 



Beckmannia erucaeformis (L.) Host. — Corvallis, Sept. 21, 191 1, 

 1183; south Mary's River, Sept. 30, 1914, 3144, Oak Creek, July 29, 

 1915, J14S type, Aug. 14, 1915, 3026, May, 1916, G. B. Posey. 



Evidently the most common rust in Oregon on this host. It differs 

 from U. Hordei, which is in general a southern form not known on the 

 Pacific coast, in the larger teliospores which show distinct longi- 

 tudinal ridges. From U. Jacksonii (cf. 192) this species differs in the 

 thickened apices of the teliospores. No clue is available as to the 

 aecial host. The rust is difficult to separate from Puccinia Rhamni 

 (cf. 159) in the uredinial stage.

Sci. i: 28. 1884.

 On Alliaceae: 



Brodiaea sp. — Corvallis, May 4, 1912, F. D. Bailey, 3304, April 

 25, 1915, 2623. 



This opsis-form is evidently common in western Oregon. The rust 

 is usually found attacking the tips of the leaves early in the spring. 

 Aecia usually predominate, the telia being inconspicuous and easily 

 overlooked.
