108 ARTHUR: NEW SPECIES OF UREDINEAE 
A somewhat similar error occurs in connection with Puccinia 
missourtensis (l. c. p. 146). In making studies for the genus 
Allodus, Professor C. R. Orton made the discovery that the host, 
consisting of a small fragment, 2 by 3-5 cm., is not Ranunculus 
recurvatus as stated by the collector, but is in reality Anemone 
cylindrica A. Gray, and that the telia on it belong to Puccinia 
Anemones-virginianae Schw., while the aecia belong to P. Clema- 
tidis (DC.) Lagerh. 
A number of grass rusts, now known only in their uredinial 
form, undoubtedly belong either to the genus Puccinia or Uromy- 
ces. For the sake of convenience in listing such species it is pro- 
posed to transfer two of these names without waiting for the 
discovery of the telial form. They will be placed under Puccinia, 
as the chances are two out of three that they will eventually be 
found to belong in that genus rather than in Uromyces. In the 
case of three other species of grass rusts long known under the 
genus Uredo the teliospores have recently been discovered and, 
in the case of two of them, on type material, entitling them to a 
place under Puccinia. 
The wholly new species here proposed, some sixteen in all, are 
partly taken from recent collections, but more largely from material 
which has been long in the herbarium awaiting study. While a few 
of these came from the northern states, they are largely from the 
southern border of the United States, from Mexico and the West 
Indies. I have been given the privilege to include species derived 
from the studies of Professors Jackson, Holway and Bethel, 
which with others here published are shortly to be made part of 
the seventh volume of the North American Flora. 
Puccinia egressa nom. nov. 
Puccinia egregia Arth. Bull. Torrey Club 38: 370. 1911. Not 
P. egregia Arth. 1905. 
Through pure inadvertance the same specific name has been 
given by the writer to two unrelated rusts. The first opportunity 
since noticing the mishap is now taken to replace the later one, 
the species being on Baccharis oaxacana Greenm., still only known 
from the type collection made on Mt. Oaxaca, Mexico, by C. G. 
Pringle, in 1894.
