Synopsis of Canadian Ferns and Filicoid Plants. 287 



Bljtt. L. chamcpcyparissias, Braun. L. sahincefoUum, Willd. — Not 

 uncommon in the woods about Kingston, and in rear ; Newboro-on-the 

 Rideau ; Gananoque River ; River Ristigouche, St Lawrence Gulf, and 

 St Joseph's Island opposite Campment D'Ours, Lake Huron, R. Bell, 

 jr. ; Ramsay, Rev. J. K. M'Morine, M.A. ; pine grove near Blue Church 

 Cemetery and woodlands west from Brockville, not common, B. Billings, 

 jr.; Three Rivers and Temiscouata, C.E., P. W. Maclagan, M.D. ; 

 sandy woods around Castleton, sterile hills Brighton and Murray, 

 J. Macoun ; L'Orignal and L'Anse au Cousin, Gaspe, J. Bell, B.A. ; 

 Trois Pistoles, M. L'Abbe Provancher ; London, W. Saunders. To this 

 species is referred L, sdbinoefolium^ Willd , L. chamcBcyparissias, A. 

 Braun, with branches more erect and fascicled. Professor Asa Gray 

 remarks : — The typical form of L. complanatum, with spreading, fan- 

 like branches, is abundant southern (in N. States), while northward it 

 passes gradually into var. sahincefoliuon." I have only one rather im- 

 perfect specimen of the European L. chamcecyparissias, collected at Bonn, 

 on the Rhine, by my friend Professor G. S. Blackie, which does not 

 diiFer in the branching from ordinary Canadian forms of L. complana- 

 tum. It appears to be quite a common species in the States, for I have 

 it from a great many places. 



Selaginella. 



S. spinulosa, A. Braun. — Small, prostrate, leaves lanceolate, acute, 

 spreading, spinosely toothed ; fertile branch stouter, ascending spike 

 sessile. Selaginella spinulosa, A. Braun, Blytt, Norges Fl. Lyco-

 Selaginella spinosa, Beauv. Selaginella selaginoides, A. Gray, Man. 

 Bot. N. States, p. 605.— Gaspe, John Bell, B.A. ; Canada, Michaux ;

 Bot. N. States ; Canada, Pursh, who observes : " The American plant 

 is smaller than the European." 



Stachygynandrum. 



S. rupestre, P. Beauv. — Much branched, leaves slightly spreading 

 when moist, appressed when dry, carinate, hair-tipped ; compact and 

 moss -like, growing on bare rocks. Selaginella rupestris, Spring, A,

 Islands at Brockville, &c. ; Longpoint on the Gananoque River ; near
