6 BOTANICAL GAZETTE [JULY 



the Uromycetes inhabiting grasses this is readily distinguished 

 by the irregular and peculiar shape of the teleutospores ; while 

 some are no longer than wide, many are oblong or nearly lanceo- 

 late, while the apex has a multitude of forms ; sometimes 

 straight, sometimes acutely acuminate, often turned sidewise, 

 beak-like, not seldom double, and occasionally suggesting the 

 appendages at the apex of the teleutospores of Puccinia coro- 

 nata!' The paler, more slender, and poorly nourished teleuto- 

 spores of the inland form are associated with the smaller sori, 

 which are sunken and compressed between the stout nerves of 

 the leaves. 



If there are specific differences between the seashore and 

 inland forms of this rust, they can only be established with cer- 

 tainty by cultures. Morphological characters derived from the 

 uredo and teleuto stages show no differences that are not 

 accounted for by ecological conditions. 



The species was first recorded by Farlow^ in 1878 under the 

 name Urom, Junci. The following year the same collection was 

 distributed in Ellis' North Anier, Fungi, No. 239, under the name 

 Urom, Junci var. Spartinm^ but without description. Later study 

 resulted in raising the form to specific rank, as given in the 

 synonymy above.
