Contributions to the Mesozoic flora of the Atlantic coastal plain, 
X.—Maryland 
Epwarp WILBER BERRY 
One of the first attempts to correlate the strata of the Atlantic 
coastal plain with those of Europe, that by John Finch! in 1824, 
was based on the amber-bearing lignites of the Magothy formation 
found at Cape Sable in Anne Arundel County, Maryland, while 
only a few years later Richard Harlan? mentions ‘* dicotyledonous 
lignite” from the deep cut of the Chesapeake & Delaware canal. 
These are among the earliest references to the remains of former 
vegetation preserved in the Upper Cretaceous deposits of Mary- 
land. Two incidental references by Ward* show that the im- 
portant plant-localities at Grove Point, Bodkin Point, Round Bay, 
and Brightseat were discovered between 1887 and 1893 and collec- 
tions made from them. These, however, remained unstudied in 
the National Museum collections until the writer took up the 
study of these floras in 1904. Meanwhile but a single paper had 
appeared which was devoted to Maryland Upper Cretaceous 
paleobotany. This was a short paper by Knowlton! describing 
the structure of the amber bearing lignite at Cape Sable. 
The writer has published several preliminary papers* containing 
descriptions of Upper Cretaceous plants from the Maryland area. 
The last of these, published in 1911, brought the known Magothy
