 Carpites liriophylli Berry, 1906, Bull. Torrey Bot. Club, vol. xxxiii, p. 174. 



Description. A ligneous winged seed or carpel, ovate in general out- 

 line, flattened, curved somewhat toward the thickened proximal end 

 which also shows a vertical scar of attachment about 3 mm. in length. 

 Surface somewhat striated, 2.5 cm. to 3 cm. in length, 6 mm. to 7 mm. in 

 maximum width midway between the ends ; distal end more narrowed than 

 proximal, acuminate; proximal end obtuse. 



This species was described by Lesquereux from the Dakota group and 

 based on a single specimen found in association with the problematical 

 genus Liriophyllum. It reappears in the Magothy in more typical form 

 and appears to be definitely related to the genus Liriodendron. 



Occurrence. MAGOTHY FORMATION. Deep Cut, Delaware. 



Collection. Maryland Geological Survey.

' enus NELUMBITES Berry 

 [Maryland Geol. Survey, Lower Cret., 1911, p. 462] 



The genus Nelumbites was proposed by the writer in 1911 for ancestral 

 forms related to the modern genus Nelumbo, with Menispermites vir- 

 giniensis Fontaine 1 from the Patapsco formation of Maryland and Vir- 

 ginia as the type. One additional Patapsco species, Nelumbites tenui- 

 nervis (Fontaine) Berry, was described. Additional species include the 

 following Magothy form and probably the large-leafed Nelumbo kempii 

 Hollick 2 from the same formation in New Jersey and on Long Island and 

 Marthas Vineyard. Small-leafed forms also occur at higher horizons in 

 the Montana group and in the Laramie and Shoshone group of the West.
