250 BROOKLYN BOTANIC GARDEN MEMOIRS 
This species, described from a collection on Zygadenus 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, 1917, on a phanerogamic specimen of S. gramineum 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.
