Notes on the Flora of Ontario. 221 



Thurso, at Wingham, Ont, and at Fort William, near Port Arthur, Lake 

 Superior. 



The next is a water species with bright yellow flowers, R. multifidus, 

 so named from its very much dissected leaves. Three forms were 

 formerly included under this species but a better knowledge of their 

 characters has been obtained and they are now easily separated. This 

 species is always found in slow-flowing or stagnant water and when 

 flowering has floating elongated fistulous stems and showy yellow 

 flowers. 



The var. terrestris, Gray, is a series of shallow water or wet soil 

 forms which creep, rooting in the mud, with shorter stems and emersed 

 coarsely dissected leaves and flowers and fruit smaller. Both the above 

 are general throughout the province but seldom collected. This form 

 is abundant in Malloch's Bay near the C. P. R. station, Ottawa. 



A very peculiar species, R. Lapponicus, was described, as 

 Antmone fiudicaulis by Dr. Gray (see Manual, Page 38) from imperfect 

 specimens, which weie without flowers. Prior to that time it had been 

 collected in a peat bog where Port Arthur now stands by the Rev. J. K. 

 McMorine and in 1884 in peat bogs, Nipigon river by the writer. 



A small and interesting species, R. Flammula, L. var. reptans, E. 

 Meyer, is found creeping amongst gravel in, or close to, the water on the 

 shores of all lakes and large streams throughout the country. It may 

 be easily known by its creeping habit, linear or lanceolate leaves and 

 small yellow flowers. Very common at Paugan Falls on the 

 Gatineau. 



Following this little species is a tall robust one, R. ambigens, 

 Watson nearly two feet high, rising from a decumbent base. Its leaves 

 are lanceolate, acute, generally serrulate, 3 to 4 inches long and from one 

 fourth to half an inch wide. This species has been gathered near Port 

 Colborne and should be looked for in the marshy country on the 

 Welland Canal. 



Our next species, R. rhomboideus, Goldie, has had a variety of names 

 as it begins to flower when hardly an inch above the ground, just as 

 the snow disappears and continues in bloom for two months. This is a
