differ sufficiently in habit and general character to constitute good- 

 species. Atjpresent species in America are, in general, too ill-detined, 

 and it is the opinion of the writer that all permanent forms should be- 

 described, and specitic distinctions placed on record, so that future 

 workers may have less ditficulty in working up the plants of any 

 region than has been experienced by me in elaborating the flora of 

 Canada. Specimens referred here were collected at Vancouver city,. 

 on Burrard Inlet, by Piof. Fowler. They agree precisely with AIi-. 

 W. Boott's description, and specimens distributed by Suksdorf

Deep cedar swamps, in sphagnum. Canada. (Hooker, Fl.) We have 

 no Canadian specimens of this species. Collectors should look for it in 

 Quebec and New Brunswick. The reflexed teeth of the perigynium 

 and gi-ass-like appearance of the whole plant distingui.sh it from the 

 next, which grow.s in the same situations.
