72 DAWSONS ON CEETACEOUS PLANTS FEOM VANCOUVER 



Gringko when less than half grown in early spring. It is near to S. integrifolia, Heer, a 

 Jurassic species ; but also near to S. primordialis, Heer, from the Upper Cretaceous of Grreen- 

 laud. It is, however, probably new. 



The exogenous leaves are very numerous, and belong to a number of genera, among 

 which are probably Ficus, Alnus, Betula, Quercus, Dios/ii/ros, Cimmniomum, Ceanothus, Populus, 

 Salix, Proteoides, Juglans, Rhamnus, Aralia, and possibly several others, evidencing a very 

 rich and varied forest flora of warm temperate aspect. 



The material is extensive, and requires so much working out, that it has not yet 

 been fully examined ; but it must include at least twenty sf)ecies of exogenous trees and 

 shrubs. 



The facies of the flora, as a whole, is Upper Cretaceous, and several of the species are 

 apparently identical with those found at Nanaimo and elsewhere in the southern basin 

 of Vancouver Island. Others, however, are difierent. On the whole, the assemblage is 

 of decidedly later type than that of Beaver Harbour, above referred to, and probably 

 somewhat newer than that of Nanaimo, and more resembling the Upper Cretaceous plants 

 found by Richardson at Protection Island. It is certainly more modern than the Dakota 

 group of the United States, and the Dunvegan group of Peace River, and its nearest ana- 

 logues elsewhere seem to be in the Atané and Patoot series of G-reenland, as described by 

 Heer. 



The collection will, when fully worked out, add a number of interesting species to the 

 known Cretaceoiis flora of British Columbia, which will be farther augmented by new 

 species in additional collections of Dr. Dawson, made at the Wellingtou mine at 

 Nanaimo.
