180. Airis oroboides, Hornem. Phaca oroboides, DC. P. elegans, 
elegans of Hooker’s Flora; but I have a fine specimen, so named, from 
Bourgeau’s Saskatchawan collection; and “Phaca No. 5” of the same 
collection is just like my original specimen of P. elegans, and like P. 
oroboides from Labrador communica eated by Dr. Steetz. The latter and 
Fare opean specimens have rather less slender calyx-tee ut no other 
difference is manifest. The elliptical and ro legume has a the dorsal 
suture more or less intruse. “Phaca No. 2” ourgeau’s collection 
in the Rocky Mountains is probably a variety of A, alpinus, but has a 
eae stipe to the legume and longer, very slender calyx-teet eth.
