Another Aeschynomene Rust 

 J. C. Arthur 



A specimen of rust worth special attention has been received 

 by the writer from Dr. J. J. Davis of the University of Wis- 

 consin. It was collected by A. L. Smith at Crowley, in southern 

 Louisiana, on Aeschynomene virginica (L.) B.S.P., August 9, 

 1932. It may be described as follows: 



Uredo posita J.J. Davis n. sp. Uredia caulicola, sparsa, pal- 

 lida cinnamomeo-brunnea; urediosporae globosae vel obovatae, 

 17-21 X 19-23^; episporio 1.5-2/x cr., echinulatae, poris germ. 2, 

 superequatorialibus. 



The urediospores are somewhat flattened laterally and bear 

 a pore on the flattened sides near the apex. The sorus is without 

 a peridium. It is evidently a species belonging to the Puccinia- 

 ceae. The only other species on this genus of hosts, but not on 

 A. virginica, is Uredo Aeschynomenes, found in Mexico, the 

 West Indies and South America. It is very distinct, having im- 

 bricated paraphyses, and apparently belongs to the Melamp- 

 soraceae.

A Tertiary Ephedra, a correction 



In the January -February number of Torreya a fossil 

 Ephedra was described by Dr. R. P. Woodehouse. Due to an 

 error in an addition to the page proof the name of the new spe- 

 cies was omitted. The species name was given only under the 

 cut of the fossil, it should have appeared before the description 

 on page 1 as Ephedra miocenia sp. nov.
