274 Synopsis of Canadian Ferns and Filicoid Plants. 



been found in any other part of North America. (Pursh.) Nuttall 

 states that he found it in the western part of the state, without giving 

 the locality ; but according to Dr Pickering, the specimens of Mr Nuttall, 

 in the herbarium of the Academy of Sciences in Philadelphia, are 

 marked, " Near Canandaigua, at Geddis's farm, in a shady wood, with 

 Taxus canadensis," Torrey Fl. N. Y. ii. p. 490. This fern occurs 

 throughout Europe, and also in Northern Asia. Mr Moore considers the 

 Mexican S. Lindeni as a mere variety of this species. In Europe there 

 are many remarkable varieties, of which Mr Moore has figured and de- 

 scribed more than fifty that occur in Britain. The great beauty and 

 remarkable character of many of these render them very suitable for 

 cultivation. None of the abnormal forms have as yet been found in 

 America, probably merely because they have not been looked for. 



Camptosorus. 



G. 7'hizop7iyllus, Presl. — Frond lanceolate, broad and hastate, or 

 cordate at base, attenuated towards the tip, which strikes root and gives 

 rise to a new plant ; hence this fern is called the Walking Leaf ; 

 fronds evergreen. Camptosorus rhizophylhis, Link, Presl, A. Gray, 

 Eaton, Hooker. Asplenium rJnzophyllum, Linn, in part (Linnseus's 

 name included Fadyenia proUfera^ a totally different plant), Michaux, 

 Pursh Fl. Am. Sept. ii. p. 666, Bigelow, Torrey, Beck, Darlington, 

 Lowe's Ferns, vol. v. pi. 14: a. Antigramma rhizophylla, J. Sm., 

 Torrey Fl. N. Y. ii. p. 494. Caiwptosorus rumicifolius, Link. — On 

 the flat perpendicular face of a rock in the woods, on the Spike's Cor- 

 ners side of the mills at High Falls, township of Portland, C.W., July 

 1862. In a rocky wood, a mile north-west from the Oxford station of 

 the Ottawa and Prescott Railway, upon a rock slightly covered with 

 mould, B. Billings, jr. ; mountain side west from Hamilton, also at 

 Ancaster and at Lake Medad, Judge Logic ; Wolfe Island, E. J. Fox ; 

 not rare about Owen Sound, Rev. Prof. W. Hincks, F.L.S. ; Montreal 

 Mountain, M. L'Abbe Provancher ; rather northern in its range in North 

 America, but not common anywhere in Canada. This curious fern has 

 been long in cultivation in the botanic gardens of Europe. 



Lastrea. 



L. dilatata, Presl. — Fronds spreading, broadly lanceolate, rather 

 pale but vivid green, bipinnate ; the pinnules pinnate or pinnatifid 

 with pointed lobes ; on the lower pinnae, the posterior pinnules are 

 longer than the anterior ones ; stipe with rather distant pale unicolorous 

 scales ; sori small. This description refers only to the commonest form 

 in Canada. It is a very variable species. Aspidium spinulosum, Gray. 

 — Abundant in the woods about Kingston, as Collins's Bay, &c.. Smith's 

 Falls, Odessa, woods near the Falls of Niagara, Hinchinbrook, Gana- 

 noque Lakes, Farmersville, Hardwood Creek, Delta, Upper Rideau Lake, 

 Newboro-on-the-Rideau, Longpoint ; Mouth of the Awaganissis Brook,

 M A. ; Prescott, very common, B. BiUings. jr. ; St John's, St Valentine,
