UREDINALES OF GUATEMALA 
This iDng-cycle rust has heretofore been known only from Mexico. 
Most of the teliospores in the collection number 561 are mesosporic. 
Re-examination of the type collection shows the presence of a few 
mesospores, but they are not mentioned in the published description. 
The other collection here listed also has only a few mesospores. Ap- 
parently such one-celled teliospores are most abundantly produced in 
sori first arising when telial production begins. The first stage of this 
rust is yet unknown.

This peculiar short-cycle rust, first found in Surinam and named 
Dasyspora foveolata, and later found in other parts of South America, 
was collected by Kellerman, at Los Amates, Dept. Izabal, March 15, 
1905, 5330, and reported by Kern in Mycologia /. c. under the often 
used name Puccinia gregaria Kunze. 
129. Puccinia circinata (Schwein.) comb. nov. (on Malpighiaceae). 
Genus and species undetermined. 
Through the kindness of the Director of the Royal Botanic Gardens, 
Kew, the writer has recently been able to examine a part of the type 
collection of Uredo circinata Schwein., published by Berkeley and Curtis 
in their account of "Exotic fungi from the Schweinitzian herbarium, 
principally from Surinam," Journ. Acad. Phila. 2: 282. 1853. It was 
stated to be "on the leaves of some unknown plant." 
A collection made by Kellerman, at Gualan, Dept. Zacapa, Guate- 
mala, Dec. 28, 1905, 5457, on the leaves of some plant, whose identity 
was not ascertained, shows uredinia and telia, and the uredinia exactly 
correspond to those of the rust from Surinam. The urediniospores are 
very distinctive on account of the conspicuously long echinulations. 
In the comments attached to the original description it is noted that 
"the globose spinulose spores are the distinctive mark of this fine 
species; the processes are nearly as strong as in [the teliospores of] 
Puccinia aculeata Schweinitz." It required, however, another spore 
form to make evident the systematic position of the rust, and to rescue 
the name from the limbo of species duhiae. 
The species has the same general characteristic as Puccinia inflata 
Arth., on species of Stigmaphyllon in the West Indies. In both species 
the bulbous inflation of the pedicel next to the spore is a curious and 
marked feature. From P. inflata, however, it is abundantly distinct.
