Without attempting to discuss any special points of interest connected 
with the above species, we may briefly consider the flora as a whole, 
and note how far it throws light on certain questions of botanical and- 
geological interest. There is little doubt that it was in Wealden times, 
or probably at the close of that period, that angiospermous plants first 
made their appearance as members of the world’s vegetation. In the 
Potomac beds of North America, which comprise rocks of Wealden 
age with others on a somewhat higher geological horizon, and in the 
thick series of Lower Cretaceous and Upper Jurassic plant-beds of 
Portugal, there have been discovered several undoubted examples of 
monocotyledonous and dicotyledonous species. Speaking of the 
Wealden flora, a reviewer has well said 1 : ‘ It is as if we stood at the 
mouth of a great river flowing from an unexplored interior, whose 
flotsam we anxiously interrogate for clues as to the nature of the 
unknown hinterland ; yet nothing reaches us from beyond the coast- 
belt, which we have already explored.’ In spite of the comparatively 
large number of forms at present known from these beds, there are
