 Celastrophyllum marylandicum Fontaine, 1906, in Ward, Mon. U. S. Geol. 



Surv., vol. xlviii, 1905, p. 559, pi. cxvi, fig. 7. 



Description. — Leaves elongate linear-lanceolate, 10 to 18 cm. in length 

 by about 2.5 cm. in width at the broadest part which is toward the apex, 

 from which point they narrow gradually to the broad sheathing base. The 

 latter is about 5 mm. wide with the margins approximately parallel and is 

 the part usually preserved, the upper and more delicate part of the leaf 

 lamina having usually been completely macerated or torn away before 

 fossilization. Margins entire basally for 1/3 the length of the leaf, and 

 for even a greater distance, passing distad into slight serrations which 

 gradually grade into large, shallow, rather rounded, dentate teeth. Apex 

 not clearly jn,ade out but apparently rounded. Venation indistinct; 

 basally there are several approximately parallel veins of rather fine 

 calibre, higher up in the lamina these branch in a straggling manner 

 and apparently send short branches into the teeth. Several specimens 

 of the capitate fruit (inflorescence ?) are preserved in intimate associa- 

 tion but not in actual connection with the leaves. These fruits are ellipti- 

 cal in shape, as preserved they are about 2.5 cm. x 1.2 cm., the surface 

 covered with more or less circular bosses of small size about 1 mm. in 

 diameter, somewhat suggestive of the berry-like fruits of the Aracese. 



Five specimens in all have been found and a sixth from the same 

 locality has received the name Celastrophyllum marylandicum. This 

 latter shows the venation of the upper part of the leaf, but not at all 

 clearly, nor are the veins as prominent as the published figure would 

 indicate. It has the same narrow outline, broad entire base, large irregu-
