40 ARTHUR: NEW SPECIES OF UREDINEAE 
germinate immediately upon maturity, which Rostrup kept sepa- 
rate in his genus Leptopuccinia on page 268 of the same work, 
covers the ground intended by the writer for the short cycle 
genus set forth in his Vienna paper of 1906, and for which he 
unfortunately selected the untenable name Dasyspora. The fol- 
lowing species, mentioned in the paper referred to, are here trans- 
ferred to the genus Micropuccinia, the new combinations to be 
credited to Arthur and Jackson in each instance.
