BioLocy.—There are several species of Uromyces parasitical 
upon the Leguminosz. By most botanists the above is considered 
identical with U7. ervz. As early in the year as February 8 (1884), I 
produced the 4-cidium upon a bean plant (VY. _faé@) from teleutospores 
on bean straw which had been grown for agricultural purposes. The 
latent period between placing the teleutospores on the host-plant and 
the appearance of the spermogonia was twenty-three days. The cul- 
ture was repeated on March 20 in two experiments, both of which 
were successful, the spermogonia in each case showing on April 16. 
In 1886, four cultures were made with U. evvi by placing the germi-
