250 BROOKLYN BOTANIC GARDEN MEMOIRS 



This species, described from a collection on Zygadeniis elegans 

 made by Professor Holway at Banff, Alberta, has been previously 

 known only from the original collection. The above collections 

 clearly belong here and add a new host. The only other collection of 

 Puccinia on Stenanthium known to the writer is one obtained by him 

 in January, 191 7, on a phanerogamic specimen of S. gramineiim col- 

 lected in Georgia by A. W. Curtis, now in the herbarium of the New 

 York Botanical Garden. This has been referred to P. atropuncta, 

 a species known only from east of the Rocky mountains on related 

 hosts.
