18 BURGESS ON CANADIAN FILICINEA. 
(Bull. Nat. Hist. Soc. N. B., No. IV.) the specimens collected at the Tunnel in Resti- 
* gouche by Mr. Fowler, and at Grand Falls by Mr. Jack, are named W. hyperborea. Mr. 
Jack’s Grand Falls plant, however, which I have examined, is undoubtedly true W. gla- 
bella. 
4.—W. optusa, Torr. A specimen collected amongst loose rocks at Port Simpson, on 
Portland Inlet, Northern B. Col., and supplied by Mr. J. R. Anderson, has broad though 
very thin indusia and so is undoubtedly genuine W. obtusa. This important discovery 
renders it possible that Dr. Lyall’s plants, collected on the Galton Mountains, B. Col., in 
1861, may after all be this species, and not W. scopulina, as was stated in “ Canadian 
Filicinese” (Trans. Roy. Soc. Can., Vol. II, Sect. IV, p. 174), Professor Eaton, with whom 
I have communicated on the subject, informing me, that he has never personally exam- 
ined Dr. Lyall’s specimens. Our known stations for this rare Canadian fern are now, 
therefore, two in number, and strangely far apart, the one being in Nova Scotia, the other 
in British Columbia. 
5.—W. scopunina, D. C. Eaton. Specimens, thickly glandular on the upper as well 
as the lower surface, have been received from Mr. Anderson, who says it grows abun- 
dantly amongst loose rocks on Mount Finlayson and other hills about Victoria, B. Col. 
6.—W. OrEGANA, D. C. Eaton. The range of this species has been extended along 
the Thompson River to Kamloops, B. Col., where typical specimens, but of rather stunted 
growth, were collected in crevices of dry rocks exposed to intense heat and sunlight, by 
Mr. Jas. Fletcher of Ottawa, in June, 1885. 
Genus XX.—OSMUNDA, ZL. 
1.—O. rEGAuIs, Z. Abundant around Lake Mistassini, N. EH. Terr.—J. M. Macoun. 
2.—O. CnAyToNIANA, LZ. Very abundant among boulders all around the margin of 
Lake Mistassini, N. E. Terr., and back from the lake in woods on higher ground.—J. M. 
Macoun.
