BERRY : MESOZOIC FLORA OF THE COASTAL PLAIN 187 
and more transitional in character, until where it rests upon the 
Older Potomac it is clearly estuarine. In spite of inaccuracies of 
detail, however, the inference is correctly drawn that these upper 
beds are comparable with the Tuscaloosa formation of Alabama 
(loc. cit. 391). The foregoing in a very brief way exhausts the 
references to the Cretaceous flora of North Carolina. 
During the past summer the writer, under the auspices of 
the North Carolina Geological Survey, made a reconnaissance 
by boat from the Piedmont to the coast along the Roanoke, 
Neuse and Cape Fear rivers in North Carolina and the Great Pee 
Dee in South Carolina. By far the most instructive section is the 
more or less well known one along the Cape Fear, and while it is 
not my purpose to discuss the geology in this place, a word or two 
of explanation is necessary. 
In ascending the Cape Fear the Transitional Cretaceous, which 
consists of very lignitic sands and laminated clays and sands, 
greatly crossbedded in places and carrying pyrite and glauconite, 
was first seen in the vicinity of Donohue Creek Landing, about 
fifty miles above Wilmington. From this point itis exposed at 
frequent intervals almost as far up as F ayetteville, a distance of over 
fifty miles, coming to lie with a marked unc formity upon the Older: 
Potomac beds which form the river bluffs for some fifteen miles 
below that place. As we ascend the river, getting lower down in 
in the formation, all evidences of marine conditions of deposition 
disappear, the beds becoming littoral and estuarine in character. 
Leaf-remains were observed at a number of points, in most 
cases the impressions carrying too much lignite and the matrix 
being too coarse to permit of their successful collection and preser- 
vation. Near Court House Landing, about seventy-six miles 
above Wilmington in Bladen County, these Transition beds reach a 
thickness of about seventy feet and contain lenses of rather compact 
brownish drab clay carrying good leaf-impressions which have fur- 
nished the bulk of the species enumerated in the following pages. 
Similar materials were observed at several points along the Neuse 
river and also atone locality on the Great Pee Dee river in South 
Carolina. A small collection: of identifiable leaves was made in the 
vicinity of Blackmans Bluff on the Neuse river, at which locality 
about twenty feet of transitional Cretaceous is exposed. Some of
