uredinia. The aecia were somewhat old and no uredinia were found 
on other Epilobium plants in the vicinity. Tranzschel (Ann. Myc. 7: 
182. 1909) established the connection of aecia on Epilobium with P. 
Veratri, obtaining his clew from the close morphological resemblance 
of the teliospores of this species to those of P. Epilobii DC. Bisby 
(Am. Jour. Bot. 3: 527-561. 1916) has pointed out the morpho- 
logical similarity of this species with Uromyces plumbarius (cf. 201), 
P. Epilobu, P. Epilobu-tetragoni (cf. 99) and P. Epilobi-Fletscheri.

doing little damage. It is less common on the peach. No aecial 
collections have been made in the northwest.
