F. maritimum, Macoun, Cat. Can. Plants, Vol. I., p. 408. 



Turner's Head. Labrador. (Rev. A. Waghorne.) Brack- 

 ley Point. P.E.I. ; Jupiter River, Anticosti, Que.; Qualicum 

 and Point Holmes, Comox, Vancouver Island. Herb. No. 

 1505. (JbAn Macoun.) Hass River, N.B. {Fowler.') We 

 do not believe, that this plant, " wherever found," in Canada, 

 has been introduced. Prof. Small found among our speci- 

 mens no representatives of P. maritimum, and as our speci- 

 mens of P. Rayi are from widely separated and remote 

 localities on the Atlantic and Pacific coasts, it seems prob- 

 able that we have but one species in Canada, and that it is, 

 at least in part, indigenous. 



(17.) P. Paronychia, C. & S. 



Beacon Hill, Vancouver Island. {John Macoun. C. F. 

 Fewcombe.') 



(18.) P. ERECTUM, L. 



Our only specimens of this species are from Winnipeg, 

 Man. ; Banff, Rocky Mts, Herb. No. 1,485. {John Macoun.) 



Other specimens referred here by Prof Macoun, Cat. Can. 

 Plants, Vol. I., p. 407. are now included under other species.

 Macoun.) 



(20.) P. DouGLASii, Greene. 



P. tenue, Macoun, Cat. Can. Plants, Vol. I, p. 408. 



Not rare from Ontario to British Columbia. We have 

 apparently no P. tenue, in Canada. 



Prof Small says of this species, " P. Bouglasil can be 

 distinguished from its relative P. tenue at a glance, and is 

 beautiful!}^ distinct, as Prof. Greene has pointed out, by its 

 one-ribbed leaf in place of the three-ribbed of P. tenue, and 

 the much longer, narrower and pedicelled, diooping fruit, 

 instead of the short, thick, sessile, ei-ect fruit of that plant."
