New species of Uredineae—VII 
JOSEPH CHARLES ARTHUR 
Since the publication of the last number in this series* of 
articles many species of rusts have come to light, which appear to 
be undescribed. Some of these forms are the discovery of col- 
lectors in the field, and have been sent to this laboratory for 
study; other forms have been brought to light in the course of 
the monographic study of the order in preparation for the North 
American Flora; and a few forms have been known for many 
years and have passed under collective names or been placed in 
the wrong genera owing to imperfect knowledge of the spore- 
forms. The writer is appreciative of the kindness of his many 
correspondents who have sent material for study, and who, in 
most instances, have placed no restrictions upon the use of it, 
a courtesy to the general cause of scientific advancement. 
In the last preceding number of the series a description was 
published of a rust on an undetermined species of host, locally 
known as “Washington Vine.” It was given the name Uredo 
inquirenda, with the hope that the matter would attract the atten- 
tion of some one who could suggest the probable identity of the 
host. This hope has been realized. Mr. Elam Bartholomew 
writes that the common Matrimony Vine (Lycium vulgare Dunal) 
is known in some localities as ‘‘Washington Vine.”” From this 
suggestion it has been easy to verify the host of Uredo inquirenda 
as Lycium vulgare, and to show that the new name is a synonym 
of Puccinia slobosipes Peck. une es
