Synopsis of Canadian Ferns and Filicoid Plants. 285 



fastigiate ; leaves in about 8 rows, more or less convergent or spreading, 

 lanceolate, acuminate, entire ; sporangia in the axils of the common 

 leaves (not in spikes). Lycopodium Selago, Linn., E. B., Bigelow, Beck, 

 Hook, and Grev., Torrej Fl. N. Y. ii. p. 508, Gray. — Labrador, 

 Hudson's Bay to Rocky Mountains, Hook. Fl. B. A. ; shore of Lake 

 Superior and northward. Professor A. Gray, Man. Bot,, N. S., p. 603. 

 I have not seen Canadian specimens of this plant. The stations known 

 show that it encircles Canada, and some of them are probably within 

 our limits. Principal Dawson obtained the alpine variety on the White 

 Mountains, Herb. Bot. Soc, Canada. It is a rare plant in the United 

 States. There are two forms of this species (both of which are figured 

 by Dillenius). a. sylvaticus, leaves convergent, almost appressed. /3. 

 alpinus, leaves widely- spreading, stems shorter. 



P. lucididus. Stem dichotomously divided into long erect branches ; 

 leaves bright green, in about 8 rows, reflexed, linear-lanceolate, acute, 

 denticulate ; sporangia in the axils of the common leaves (not in spikes).

 Selago amei^icana, foliis denticulatis refiexis, Dill. Hist. Mus. t. Ivi. — 

 Gananoque Lakes, Collins's Bay, Newboro-on-the-Rideau, woods in rear 

 of Kingston, &o. ; Prescott, common, B. Billings, jr. ; Nicolet, C.E., 

 St Catherine's and Grantham, P. W. Maclagan, M.D. ; Belleville, in 

 swamps and cold woods, rather common, J. Macoun ; River Ristigouche, 

 St Lawrence Gulf, R. Bell, jr., C.E. ; L'Orignal, J. Bell, B.A. ; London, 

 W. Saunders ; Ramsay, Rev. J. K. M'Morine, M.A. This species is 

 stated by Professor Torrey to be rather common in New York State. 

 " Frequently bears bulbs instead of capsules," Pursh. 



[P. alopecuroides, P. Beauv. — The habitat " Canada" is given for 

 Lycopodium alopecuroides, Linn., in the " Species Plantarum," ed. 3, 

 vol. ii. p. 1565 ; but it is probably not a Canadian plant.] 



P. inundatus, P. Beauv. — Stems prostrate, adherent to the soil, the 

 fertile ones erect; leaves secund, yellowish green, lance-awl-shaped, 

 acute ; sporangia in distinct, terminal, leafy, sessile, solitary spikes. 

 Lycopodium inundatam, Linn., E.B., Michaux, Pursh, Beck, Tucker- 

 man, Torr. Fl. N. Y. ii, p. 508, Gray. Plananthus inundatus, 

 Beauv. L. alopecuroides, Linn., in part? — In cedar swamps and over- 

 flowed woods, Canada, Pursh. Professor Torrey notices its occurrence 

 in the north-western part of the State of New York. Professor Gray 

 observes, that the leaves are narrower in the American than in the 

 European plant, and suggests that it may be a distinct species. I 

 have not yet seen Canadian specimens. 



Lycopodium. 



L. clavatum, Linn. — Stems robust, and very long, prostrate, rooting, 

 forked, with short ascending branches ; leaves pale, incurved, linear- 

 awl-shaped, tipped with a white hair point ; sporangia in scaly catkins, 

 which are usually in pairs on common peduncles. Lycopodium clavatum, 

 Linn., E. B., Michaux, Pursh, Bigelow, Beck, Darlington, Spring, Hook.,
