DESCRIPTION OF SPECIES. 95 



from the midrib, (;urviug in passing toward the borders, camptcjdrome, not 

 coniiivent. 



The fragment is 14°" long, 3. 5°" broad at the middle, in the broadest part, 

 equally but gradually narrowed upward and downward, joining the base of 

 the tliick midrib in decurring to it, apparently pointed at apex. 



Though the leaf has some likeness to those of Ficus BoihoHfli, it evi- 

 dently differs, especially by the great thickness of the secondaries, none of 

 them being basilar and all in irregular position; yet it is evidently referable 

 to Laurus, and comparable especially to L. nectandroides Ett. (Flora v. Bilin, 

 pt. 2, p. 6, PI. XXXI, Figs. 6, 7), the leaves of which are only smaller.

Laubophyllum ellsworthianum Lesq. 

 PI. XIII, Fig. 7. 



Quercus ellsworthiana ? Lesq., Ciet. Fl., p. 65, PI. vi, Fig. 7 ; Cret. and Tert. Fl., p. 39. 



Leaves subcoriacenus, with surface polished, lanceolate-pointed, rounded 

 and broadly cuneiform to the base; borders entire, undulate; median nerve 

 thick, percurrent; secondaries oblique, camptodrome, simple or forking. 



This leaf, which is preserved entire, is lO-O*"" long, 2.5°"" broad in the 

 middle, and has the secondaries, 13 or 14 pairs, inequidistant though parallel, 

 either straight or slightly curved, at an angle of divergence of 40° to 50°, 

 forking at or above the middle. This character is peculiar and well marked 

 upon a fragment of a leaf figured in my Cret. Fl. as Q. elhwortliiana Lesq. 

 But the general facies of the leaf as seen from the specimen figured here 

 is rather that of leaves of LaurinejE. Its true relation is therefore still 

 uncertain.

Leaves rather small, thin, membranous, palmately triplinerved from 

 the base and trilobate from above the middle, rounded in narrowing to the 

 obtusely cuneate base ; borders entire ; lobes short, erect, the median a
