8. Deyophyllum (Quercus) latifolium, sp. nov. 



Leaf large, oval, obtuse at the top and base, siuuate-cleutate, with 

 teeth obtuse or obtusely pointed; lateral veins on an acute angle of 

 divergence, straight to the borders, forking once or twice. 



The characters of nervation, especially of the secondary and tertiary 

 veinlets, are coinparable to those of the Chestnut, as the secondary veins 

 enter the teeth, and thick nervilles pass outof them from near and along 

 the borders. This last character, however, is the same in the species of 

 Oaks of Cretaceous origin, which have been referred to the genus Dry- 

 oiiliyllum. In this leaf the veins fork once and near the base twice, 

 as in some leaves of Castanea. Castanea Sausmanni, Drk., from the 

 ' Quadersandsteiu of Blankeuburg, is closely allied to this species. 



9. POPULUS ARISTOLOCHIOIDES, Sp. nOV. 



Leaves thick, coriaceous, broadly ovate-obtuse, round or truncate at 

 base, entire, five-nerved from the top of the petiole ; lower primary veins 

 open, with one pair of thin marginal veins underneath; inner lateral 

 veins oblique at a more acute. angle of divergence than the secondary 

 ones, all branching, thick, or inflated, anastomosing in curves toward 

 and along the borders. 



The top of the leaf is erased, but it appears to be obtuse or obtusely 

 pointed. By its consistence and its nervation, this species is referable 

 to the section of the coriaceous Poplars. It is compar^ible also to 

 species of Am to ?oc7»'ft. 



10. Ficus DISTORT A, sp. nov. 



Fragment representing the upper half of an obovate, uuequiiateral, 

 pointed leaf, apparently narrowed to the base, with a thick pinnate 

 nervation ; upper secondary veins, six pairs, diverging forty degrees, 

 close, equidistant, and parallel, curving abruptly near the borders, which 

 they follow in double festoons. The nervation of this fragment, its are- 

 olation, both very distinct, and also the uuequiiateral shape of the leaf, 

 refer it to Ficus. 



11. Laurus prote.efolia, sp. nov. 



Leaves subcoriaceous, long, lanceolate, tapering up from below the 

 middle to a long acumen, narrowed to the base ; middle nerve grooved ; 

 lateral veins oblique,- thirty degrees, thin, curving to and along the 

 borders, parallel, except the lower pair, which is more oblique. The 

 form of these leaves is similar to that of Proteoides daplmogenoides, as 

 represented in the Cretaceous Flora (PI. XV, figs. 1 and 2). 



12. Andromeda acuminata, sp. nov. 



Leaf thickish, narrowly lanceolate, narrowed to a long acumen, grad- 

 ually decreasing to the base, borders entire ; middle nerve thick ; lateral 

 veins close, parallel, subequidistant, in an acute angle of divergence; 

 areolation minute, punctate. 



This species is related to Andromeda Parlatori, Heer, of the Creta- 

 ceous formations ; but the nervation is different. . 



13. Aristolochites infundibuliformis, sp. nov. 



Leaf coriaceous, entire, broadly ovate, peltate, five-nerved from the 

 upper part of the point of attachment of the petiole ; lower veins nearly 

 :So. 5—11
