276 THE CANADIAN NATURALIST. [Aug. 



information of the latter station T am indebted to the kindness 

 of Judge Logie of Hamilton. This fern appears to be still rare 

 in cultivation among the fern-fanciers of Europe. It -was intro- 

 duced to Britain in 1812 by Mr. John Lyon of Dundee. 



A. eheneum, Aiton. — Frond erect, lance-linear, pinnate ; pinnae 

 numerous, lanceolate (the lower oblong), sessile, slightly auricled at 

 base and finely serrate ; rachis blackish-brown, shining. As2)lenium 

 ebeneum, Aiton, Hortus Kewensis, ed. 2, vol. v, p. 516, Gray, Eaton, 

 J. Smith, Lowe's Ferns, vol. v, pi. 2. A.poti/podiolies, Schkr. — 

 Eocky woods, Brockville, B. Billings, jun. ; the only locality in 

 Canada from which I have seen specimens.* Although so rare 

 with us, this species appears to be not uncommon in the United 

 States. Gray speaks of it as " rather common ; " I have specimens 

 from Schooley's Mountains, West point, N. Y., Providence, Phil- 

 adelphia, &c. Judging from Mr. Eaton's indication in Chap- 

 man's Flora, it again seems to decrease in the south, so that its 

 present headquarters are in the Nothern States. 



\_A. marinum, Linn. — Frond broad and leafy, linear-lanceolate, 

 tapered above, pinnate ; pinnae ovate-oblong or linear, oblique, 

 shortly stalked, rarely pinnatifid, the upper ones confluent, stipe 

 brownish, rachis brown below, green and winged above, sori large, 

 linear, oblique; grows on rocks. Asplenium marinum, Linn., 

 Moore, J. Smith, &c. A. loetum, Hort. — New Brunswick, E. N. 

 Kendal, in Hook. Fl. Bor. Am. I cannot learn that this fern has 

 been subsequently found in North America, and hope, therefore, 

 that botanists will look for it on the rocky shores of New Bruns- 

 wick. It usually grows out of the crevices of shore-cliffs, and is 

 very limited in its geographical range, growing, according to 

 Moore, only in the western part of Europe, crossing from Spain 

 to Tangiers on the African coast, and being again met with in 

 Madeira, the Azores, and Canary Isles.] 



A. theJypteroideSj Michaux. — Fronds large oblong-ovate, pin- 

 nate; 'pinnae lancelolate, acuminate, from a broad sessile base, and 

 deeply pinnatifid, the lobes oblong, minutely toothed. Asplenium 

 thelypteroides, Michaux, Pursh, Bigelow,Torrey, Beck, Darlington, 

 Gray, Eaton. Dq^lazium tlielypteroiJes, Presl, J. Sm. — In rich 

 woods, DeSalaberry, west line, W. S. M. D'Urban ; Minvin's 

 woods, &c., Prescott, B. Billings, jr. ; Beloeil Mountain, P. W. 

 Maclagan, M.D. ; moist woods near the Hop Garden, Belleville, 

 rare, J. Macoun (a deeply serrated, leafy form) ; Ramsay, Rev. 



* Subsequently found near Belleville by Mr. Macoun.
