286 Synopsis of Canadian Ferns and Filicoid Plants, 



Torrey, Gray. L. tristachymn, Pursh ? L. integrifolium, Hook. 

 L. aristatum, Humboldt. — Occasionally found in the woods in rear of 

 Kingston, but not common ; Newfoundland, Hook. Fl. Bor. Am. ; 

 between Thessalon and Missisaugi Rivers, Lake Huron, Bell, jr. ; 

 Prescott, common, B. Billings, jr. ; Three Rivers, Temiscouata, and 

 Wolfe Island, P. W. Maclagan, M.D. ; Seymour, in pine woods, rare, 

 J. Macoun ; Ramsay, Rev. J. K. M'Morine, M.A. ; River Ristigouche, 

 St Lawrence Gulf, R. Bell, jr. ; London, W. Saunders, C.E. ; L'Orignal 

 and L'Anse au Cousin, Gaspe, J. Bell ; Belmont. The spores, chiefly of 

 this species, constitute pulvis lycopodii, which is used by apothecaries, 

 and was at one time employed for making artificial lightning in the 

 theatres. 



L. annotinum, Michaux. — Stems very long, prostrate, creeping, forked, 

 with ascending branches ; leaves bright green, spreading or slightly 

 deflexed, in about five rows, linear-lanceolate, mucronate, serrulate ; 

 sporangia in scaly catkins, which are sessile, solitary, oblong- cylindrical, 

 thick. Lycopodium annotinum, Michaux, E. B., Pursh, Beck, Tucker- 

 man, Torrey, Fl. New York State, ii. p. 509. — Pine forests in Hinchin- 

 brook ; rocky woods in Pittsburg, on the north bank of the St Lawrence, 

 near Kingston ; Gananoque Lakes ; L'Anse au Cousin, Gaspe, John Bell, 

 B.A. ; Prescott, common, B. Billings, jr. ; Riviere du Loup, Nicolet, 

 Montreal, and Kingston, P. W. Maclagan, M.D. ; Belleville, in cool 

 woods, common, J. Macoun; Ramsay, Rev. J. K, M'Morine, M.A. ; 

 Priceville, C. I. Cameron, B.A. ; Newfoundland, Hook. Fl. Bor. Am. ; 

 St Augustin and Cap Tourmente, M. L'Abb^ Provancher. Frequent in 

 New York State, according to Professor Torrey. Of this species there 

 are two forms, only one of which, the normal one, or type, I have as yet 

 observed in Canada. The var. (3 alpestre, Hartm. Scan. Fl., having 

 broader, shorter, paler, less spreading leaves, I have from the Dovrefieldt 

 (T. Anderson, M.D.), Lochnagar (A. Croall), and entrance to Glen Fee, 

 Clova, where I found it growing with the typical form. 



L. dendroideum, Michx. — Stems upright, bare below, bushy above 

 (giving the plant a tree-like aspect), arising from a long creeping rhizome, 

 leaves more or less appressed ; sporangia, in scaly catkins, which are 

 sessile, cylindrical. Lycopodmm dendroideum, Michx., Pursh, Bige- 

 low. Hook., Beck, Darlington. L. ohsciirum, Linn., Bigelow, Oakes. — 

 White cedar woods near Bath, abundant, and throughout the woods 

 generally in rear of Kingston ; Gananoque River ; Priceville, C. L 

 Cameron, B.A. ; Prescott, common, B. Billings, jr. ; Nicolet, Mount 

 Johnson, and Montreal, P. W, Maclagan, M.D. ; Seymour and Cra- 

 mahe, in cold moist woods, J. Macoun ; River Ristigouche, Gulf of 

 St Lawrence, R. Bell, jr. ; Ramsay, Rev. J. K. M'Morine, M.A, ; New 

 Brunswick, Hook. F. B. A ; Osnabruck and Prescott Junction, Rev. E. 

 M. Epstein ; London, W. Saunders ; Harrington, L'Orignal, and Gaspe, 

 John Bell, B.A. ; St Joachim, M. L'Abbe Provancher. 



L. complanatum, Linn. — Stems rhizome-like with ascending branches, 

 which are dichotomously divided, flattened ; leaves short, in four rows, 

 those of two rows imbricated, appressed, of the other two somewhat 

 spreading; sporangia in scaly cylindrical catkins, in twos, threes, or 

 fours, on a common peduncle. Lycopodium complanatum. Linn., Gray,
