504 GEOLOGICAL SURVEY OF CANADA. 



Var. laevigatus, Torr. & Gray. On slopes along the Flathead 

 Kiver, Eocky Mountains, B.C. (Dawson.) 



121. RHAMNUS. 



(405.) R. alnifolia, L'Her. Flathead River, Eocky Mountains, 

 B.C. (Dawson.) 



(406.) R. Purshiana, G-ray's Landing, near the mouth of the 

 Fraser, B.C., 1883. Cadboro' Bay and Saanich, B.C., 1885. (Fletcher.) 



122. VITIS. 



Page 97. 



(408.) V. Labrusca, Linn. For this substitute V. cestivalis, as 

 all the specimens from Point Pelee are of this species. Climbing high 

 over trees at Foster's Flats below the Whirlpool, Niagara River, also in 

 thickets around Queenston Heights. (Macoun.) 



(410.) V. riparia, Michx. All references in Part I, under No. 

 409, belong here. Up to the present we have no authentic record of 

 the occurrence of typical V. cordifolia in any part of Canada. The 

 Vitis found on the Island of Orleans is this species, and Dr. Burgess 

 writes that the vine found at Emerson, Man., is the same. The one 

 seen by myself from the deck of a steamboat along the Assiniboine 

 must be it likewise. I allow V. cordifolia to stand as it is barely possible 

 it may yet be found along Lake Erie. V. Labrusca must be excluded. 

 (Macoun.) 



125. ACER. 



Page 99. 



(418.) A. glabrum, Torrey. On mountain slopes from Ka- 

 nanaskis through the Rocky and Selkirk Mountains, Lat. 51. It 

 seldom attains an elevation of 6,000 feet, and is always a mere shrub 

 in damp ravines. 



126. NECUNDO. 



Page 100. 



(422.) N. aceroides, Moench. Within the last ten years this 

 tree has been extensively planted in Ontario and grows with great 

 rapidity, but is not very ornamental. There are a number of fine trees 

 up the valley of the Don at Toronto. (Burgess.) Three trees in a 

 clump, between Cooksville and Port Credit, Ont. (,/. Ades Fowler.)
