Aus. 27, ro16, Hs P. Barss, 3395. 
This species may be distinguished from other North American 
Polygonum rusts by the medium-sized teliospores (16-21 by 26-35 yu) 
with wall of uniform thickness, without hyaline umbo. It is not 
known elsewhere in North America on the first mentioned host and 
otherwise only from Washington on P. Newberryi. Aecia are un-

Allium acuminatum Hook.—Hood River Co., June 10, 1917, Leroy 
Childs. 
This rust may be distinguished from other Allium rusts by the 
strongly developed stroma in the telial sori, and the tendency to form 
confluent telia covering large areas on the stems and leaves. The 
teliospores are large (16-26 by 40-61 y), thickened to 4-10 yp at the 
apex.
