This species is especially wide ranging. It was described originally from the Cenomanian of 

 Moravia, and has since been recorded from the Cenomanian of Saxony and the Cenomanian and Turonian 

 of Bohemia, from the Atane beds of Greenland, the Dakota sandstone of the West, and from Martha's 

 Vineyard to Texas along the Atlantic coast. It ranges upward into the Black Creek formation of North 

 Carolina, and is not rare in the Middendorf beds of South Carolina. In the Tuscaloosa formation of 

 Alabama the species has not been commonly met with, but this may simply be due to accidents of 

 preservation. 



Occurrence.— Magothy formation. Deep Cut, Delaware; Grove Point, Cecil County; Round 

 Bay and Little Round Bay, Anne Arundel County, Maryland. 



Collection.— Maryland Geological Survey. (Op. cit., p. 870.) 



DESCRIPTION. 



S. — E. latifolia Hollick. 



With Plate lxxxi, figs, 6, 7. - - 



Following is the original description : — 



Eucalyptus latifolia Hollick, 1907, Mon. U.S. Geol. Survey, vol. 1, p. 97, pi. xxxv, figs. 1-5 (1906). 

 Berry, 1910, Bull. Torrey Bot. Club, vol. xxxvii, p. 26 (1910). 



Description. — Leaves elongate-ovate in outline, tapering to a somewhat abruptly attenuated 

 and more or less curved or flexuous tip. Base cuneate. Length about 15 cm. Maximum width, about 

 half-way between the apex and the base, about 5 cm. Midrib stout, flexuous. Secondaries thin, numerous, 

 diverging from the midrib at angles of from 45° to 50°, nearly straight or flexuous, their tops joined 

 by a marginal vein. Margins entire. Texture subcoriaceous. 



These large leaves occur in the Magothy formation of Martha's Vineyard, Long Island, and 

 Maryland. They are not uncommon at one locality in the lower Tuscaloosa of Alabama. Their relation 

 to Eucalyptus is extremely doubtful, but a change of generic reference is not considered advisable at the 

 present time. 



Occurrence. — Magothy formation. Round Bay, Anne Arundel County. 



Collection. — Maryland Geological Survey. (Op. cit., p. 870.)
