CATALOGUE OF CANADIAN PLANTS. 4T9 



(20.) T. dioicum, Linn. Common at Annapolis, Windsor and 

 Bedford, N.S. ; also on Anticosti. (Macoun.) Common on highlands 

 along the margins of streams and in the interior at Porteau, Labrador. 

 (W. E. Steams.) Frequent in New Brunswick. (^Fowler's Cat.') Very 

 common at Lake Mistassini. (J. M. Macoun.) 



(21.) T. purpurascens, Linn. Later researches show that this 

 is not an uncommon species eastward, but has been included in T. 

 Cornuti. An examination of the filaments and anthers will enable any 

 one to decide to which sjjecies a specimen should be referred. Along 

 Jupiter Eiver, Anticosti, and at Bedfoi'd, N.S. {Macoun.) Mingan 

 Islands. (St. Oyr.) Along the Ottawa below the city. (Ami.) 



Var. ceriferum, Austin. In sandy woods on Duntiing's Farm, 

 near Drummondville, Niagara Falls. {Macoun.) In an open field 

 about seven miles east of London, Ont. {Burgess.) 



(2097.) T. occidentale, Gray. On the -wooded slopes of the 

 Eocky and Selkirk Mountains, Lat. 51°. ^ {Macoun.) Eastei-n supimit

(23.) T. alpinum, Linn. Cape Chudleigh, eastern end of Hudson 

 Straits. (R. Bell.) Abundant in all the river valleys of Anticosti.

(25.) M. minimus, Linn. Souris, Plain, south of Moose Moun- 

 iain, N. W. T. {J. M. Macoun.) Cedar Hill, near Victoria, B. C. 

 {Fletcher.) It is extremely probable that the British Columbian formi 

 is a distinct species. 



(26.) M. aristatus, Benth. Near Short Creek, Souris Eiver, 

 Lat. 49°. {Burgess.) 



5. RANUNCULUS. 



(27.) R. hederaceus, Linn. This form should be B. aquatilis, 

 var. heterophyllus, as the above species is excluded by Watson in Bot. 

 California, Vol. II, 425. In pools near Victoria, B.C. {Fletcher.) The 

 various forms of B. aquatilis require careful revision, and we await Dr. 

 Gray's new work with great interest.
