In the report on the Stevens collections (Mycol. 7: 182) the 

 collection made at Mayagiiez, P. R. by Clinton, on R. aurea, as 

 well as the one from the Bahamas on R. cyperoides, both show- 

 ing only uredinia, should be transferred to Puccinia angusta- 

 toides. Not until the collections by Whetzel and Olive came 

 to hand was it possible to separate the two forms. It is found 

 that the Uromyces form has somewhat smaller, thinner-walled 

 urediniospores, with greater uniformity in size, than those of 

 the Puccinia form.
