6 Heter-cupuccinia, 2 Brachypuccinta, 2 Pucciniopsis, 7 Hemi- 
puccinia, 1 Micropuccinia, 3 Leptopuccinza, and 8 with im- 
perfectly known life histories. Very abundant are those species 
found on Mints, //elvanthus and allied genera, on grasses, 
sedges and Polygonum. Those forms formerly included under 
P. hieracit (Schum.) Mart. have been separated as far as pos- 
sible according to the recent researches of Jacky.* The high
