be if you were to go back to the original, which would now be scarcely proper. You will see by the Sp. 

 Plant, ed. 1., that the species is founded on a plant of Kalm, from Canada; and that a plant of Gronovius 

 from Virginia, is referred to it. The O.psycJiodes of Willdenow, and as far as I know, of almost all later 

 botanists, is the O. lacera of Mx.— Now, I find that the Gronovian plant is O. cristata, Willd. (the small- 

 flowered, yellow, New Jersey species,)— the specimen from Kalm, in Herb. Linn., from which the detailed 



description is drawn, is O . fiynbriata ! — a specimen with more crowded flowers, and rather smaller than

Hab. From Lake Huron (Dr Todd) to the Saskatchawan, and to swamps in the Rocky Mountains. Dr 

 Richardson, Drummond. — Notwithstanding the greater size of this plant, (sometimes a foot high,) and its large 

 foliacGous bracteas, I am much disposed to concur with Dr Lindley in the opinion that it is not really distinct 

 from P, viridis of Europe, of which I have specimens from the Altai, and from the Highlands of Scotland, 

 which can scarcely be distinguished from it. I may add too, that Mr Drummond, who must have been 

 familiar with P. viridis, marked his Rocky Mountain specimens by that name.
