OF Canada. 

 XIII. 

 Anemone riparia, Fernald, Rhodora, vol. i, p. 51. 



This species recently described by Mr. Fernald is represented 

 in our herbarium by a single specimen collected in 1882 at Made- 

 line River, Gaspd, Que., and in 1899 at Woodstock, N.B, 

 by Prof. John Macoun. Mr. Fernald gives as additional Canadian 

 stations Restigouche Co., N.B. (Fowler), and Roberval, Lake 

 St. John, Que. 



Ranunculus abortivus, L. var. eucyclus, Fernald, Rhodora, 

 vol. 1, p. 52. 



Stems more slender than in the type ; the branches slender 

 and flexuous ; leaves very thin and lucid ; the basal generally of 

 two sorts, some orbicular with a narrow or closed sinus, others 

 reniform as in typical R. ahortivtis ; flowers, achenes and receptacles 

 as in the species but smaller. 



Mr. Fernald records this plant from Lake St. John and 

 Tadousac, Que., but it is not represented among our herbarium 

 specimens of R. abortivxis. It should be looked for by Canadian 

 collectors. 



ISOPYRUM BITERNATUM, T. & G. 



Though collected before in S. W. Ontario any records of this 

 species are of interest to botanists. Mr. Leroy J. Boughner writes 

 of specimens sent to the Geological Survey department: "This 

 little plant was first collected by me during an expedition of the 

 Simcoe High School Scientific Society on May 21st, 1897. It 

 grew sparsely in a cool spot near Lynn Valley, a few miles east ot 

 Simcoe. It is supposed to have been introduced from Ohio by 

 railways." 



Hesperis matronalis, L. 



A garden escape near Victoria, Vancouver Island. (A. J. 

 Pineo. ) Not recorded west of Ontario *
