Of this extremely rare plant, a single bulb was received 
by the Horticultural Society from North West America 
eight or nine years ago ; it has continued to grow slowly in 
a peat border, and at last put forth its beautiful flowers last 
May. It has not however produced any seed, and it will 
probably be many years before it can possibly be distributed. 
Mr. Douglas, who discovered it, considered it the 
Erythronium grandiflorum of Pursh; and we adopt his opinion, 
although we confess ourselves unable to reconcile with it the 
is by that writer, that his plant has linear-lanceolate 
eaves. 
* The common Dog's-tooth violet was the oarůpwov £pvÜpóviov, or red Saty- 
rion, of Dioscorides, and hence the latter word has been adopted by the moderns.
