It also occurs on specimens in the phanerogamic collection of 
the New York Botanical Garden on Scleria hirtella Sw., col- 
lected at Markin Pena, P. R., June, 1913, II, by J. R. Johnston

A number of localities are now known for the species in the 
United States. A collection was made on Y. hirtella, at the edge 
of Long Prairie Hammock, on Camp Longview Trail, about forty 
miles southwest of Miami, Fla., Oct. 31, 1906, II and III, by 
Ernst A. Bessey. The following data have been secured from 
phanerogamic collections : in the Purdue University herbarium, 
on S. Baldwinia Torn, Everglades, Fla., June, 1877, II, A. P. 
Garber; N. Y. Bot. Garden herbarium, on Y. Baldzvinia, Ever- 
glades, Fla., March, 1892, II, J. H. Simpson 556, on Y. paiiciflora

of the species. 
This species has much darker colored and thicker-walled uredi- 
niospores than Rostriipia Scleriae Paz., or Pticcinia xanthopoda 
Syd. It also differs in its urediniospores from Uromyces Scleriae 
P. Henn., the latter having spores strongly thickened above.
