One of the species specially looked for on my journey to 

 the Columbia river region in i<^io -was L. laxi/Iorics. Douglas 

 is supposed to have collected it "about the great rapids of the 

 River Columbia," now known as Cascade Locks. 



No species resembling this one was noticed about Cascade 

 Locks, but some ten or fifteen miles farther up the river one 

 began to appear in abundance, and specimens of it were obtained 

 at Hood River, Oregon, growing in open grassy places near 

 trees. That this was L. laxifioriis I had no doubt, coming as 

 it did from the type region, and having a spurred flower, as it 

 has usually been described in our books. 



Later I discovered that my plant did not agree with the 

 figure in the Botanical Register, which shows a spurless flower 

 and a much narrower leaf. But the description accompanying 

 the plate says the upper calyx lip has "a sort of bag at its base," 

 or "basi saccati," as given in the Latin. Then I decided that 

 nothing further could be done until there was an opportunity to 

 examine trustworthy material. 



During the past summer ( 191 1) I had an opportunity to 

 examine material of what appears to be this species, in the Tor- 

 rey Herbarium at the New York Botanical Garden and at the 

 Gray Herbarium at Cambridge. According to the labels Dou- 

 glas collected these specimens at Fort Vancouver, Washington. 

 There are no other specimens in either of these herbaria that
