410 Enumeration of Plants of the Rocky Mountains. 
Hook. I possess a mere fr ragment, without fruit, of the original Phaca 
elegans of Hooker’s Flora; but I have a fine specimen, so —_ 
collection is just like my original specimen of P. elegans, and like P. ig 
oroboides from Labrador ccuhoemiesaad by Dr. Steetz. The latter ant 
European spe cimens have rather less slender calyx-teeth ; but no o' 
difference is manifest. The elliptical and sessile legume has t Je 
suture more or 8 intruse. “Phaca No. 2” of Bourgeau’s wid ! 
in the Rocky Mountains is probably a variety of A. a/pinus, but bh 
shorter stipe to the legume and longer, very slender calyx-teeth.
