114 'Synopsis of Canadian Ferns and Filicoid Plants, 



more contracted than the barren ones, " bearing sixty to eighty curved 

 fruit dots on the upper branches of the pinnate forking veins," (Eaton). 

 A. angustifolium, Michaux, A. Gray, Eaton, J. Smith, Lowe's Ferns, 

 vol. V. pi. 24. — In Canada this fern appears to be confined to the ex- 

 treme south-western point of the province ;* Maiden, P. W. Maclagan, 

 M D. ; at the Oil Wells, township of Ennislsillen, Lady Alexander 

 Russell. For information of the latter station I 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 introduced to 

 Britain in 1812 by Mr John Lyon of Dundee. 



A. eheneum, Alton. — Frond erect, lance- linear, pinnate ; pinnse nume- 

 rous, lanceolate (the lower oblong), sessile, slightly auricled at base 

 and finely serrate ; rachis blackish-brown, shining. Asplenium ehe- 

 neum, Alton, Hortus Kewensis, ed. 2, vol. v. p. 516, Gray, Eaton, 

 J. Smith, Lowe's Ferns, vol. v. pi. 2. A. polypodioidesy Sehkr. — 

 Rocky woods, Brockville, B. Billings, jr. ; the only locality in Canada 

 from which I have seen specimens. f Although so rare with us, this spe- 

 cies appears to be not uncommon in the United States. Gray speaks of 

 it as " rather common ;" I have specimens from Schooiey's Mountains, 

 West Point; N. Y., Providence, Philadelphia, &c. Judging from Mr 

 Eaton's indication in Chapman's Flora, it again seems to decrease in the 

 south, so that its present headquarters are in the Northern 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. Icetum^ 

 Hort. — New Brunswick, E. N. Kendal, in Hook. FL Bor. Am. I can- 

 not 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 Brunswick. 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 Tan- 

 giers on the African coast, and being again met with in Madeira, the 

 Azores, and Canary Isles.] 



A. thelypteroides, Michaux. — Fronds large oblong-ovate, pinnate ; 

 pinnae lanceolate, acuminate, from a broad sessile base, and deeply 

 pinnatifid, the lobes oblong, minutely toothed. Asplenium thelypteroides 

 Michaux, Pursh, Bigelow, Torrey, Beck, Darlington, Gray, Eaton. 

 Diplazium thelypteroides, Presl, J. Sm. — In rich woods, De Salaberry, 

 west line, W. S. M. D'Urban ; Mirwin's woods, &c., Prescott, B. BiL 

 lings, jr. ; Beloeil Mountain, P. W. Maclagan, M.D. ; moist woods 

 near the Hop Garden, Belleville, rare, J. Macoun (a deeply serrated, 

 leafy form); Ramsay, J. K. M'Morine, M. A. ; St Joachim, M. L'Abbe 

 Provancher ; London, W. Saunders. Not a common fern in Canada ; 

 perhaps more plentiful in the United States. I have a fine series of 

 specimens from Schooiey's Mountains (A. 0. Brodie), and others from 

 Providence. 



* Subsequently found in the Belleville district by Mr Macoun.
