 Pictoii, A. H. Mackay. 



Ranunculus recurvatus, Poiret. 

 Pictou, A. H. Mackay. 



Ranunculus bulbosus, Lmn. This old-world plant, which 

 grows abundantly as an indigenous species in middle and southern 

 Europe and parts of North Africa and in Asia, was found, at an 

 early period, to have become naturalized inseveral parts of North 

 America. It is one of the few (5) species of Ranunculus 

 described in Michaux's Flora Boreali-Americana, (1803), its loca- 

 tion being moist meadows in Pennsylvania. 



It was gathered in Canada by the Marchioness Dalhousie. 

 Morrison collected it in Newfoundland, as noted by Hooker. 

 More recently it was found in Point Pleasant Park, Halifax, 

 Nova Scotia, (July, 1884), perfectly naturalized, by Rev. Robert 

 Laing. It has also been observed near Shelburne, in the western 

 part of the Province, by Rev. Mr. Rossborough. Linnaeus 

 retained for this plant the characteristic name given to it by 

 Thalius in 1588, and it has no synonyms. 



Caltha palustrls, Linn. Marsh Marigold. In slow streams

 Bfeton, July 22nd, 1888.
