lesquereux.] ENUMERATION OF CRETACEOUS PLANTS. 341 



Quercus? poranoides, Lesqx., Cret. Flora, p. OG, PL XXX, fig. 9. 



Leaf broadly oval or nearly round, point broken, truncate at the base, un- 

 dulate on the borders, middle nerve IhicTc, lateral veins thin, subopposite, at 

 an open angle of divergence, curving to and along the borders, camptodrome. 



The reference of this fragment is as uncertain as that of the former. 



Fagus polyclada, Lesqx., Cret. Flor., p. 67, PI. V, fig. 6. 



Leaf ovate, oblong, cuneate to the base, short petioled; borders entire, 

 undulate; middle nerve straight, secondary veins close, numerous, simple, 

 parallel and craspedodrome. 



PLATANE^E. 



Platanus obtusi loba, Lerqx., Cret. Flor., p. 69, PI. VII, figs. 3, 4. 



Leaves small, not thick, palmately irregularly trilobate; lobes obtuse, short 

 with regularly undulate borders, nervation 3 to 5 palmate from a distance 

 above the base of the long petioled leaf. 



Platanus proogra, Lesqx., Cret. Flora, p. 69, PI. VII, fig. 2, and PL 



XXVI, fig. 2. 

 Leaves large, coriaceous, palmately trilobate, with short, scarcely dis- 

 tinct lateral lobes, broadly deltoid, deeply, distantly dentate to the point; 

 nervation three palmate, coarse, platanoidal. 



Platanus Heerii, Lesqx., Cret. Flora, p. 70, PL VIII, fig. 4, and PL 



IX, figs. 1 and 2. 



Leaves round or broadly rhomboidal in outline, palmately three obscurely 

 lobed; lobes short, obtuse ; borders entire or undulate broadly wedge-form 

 at base and more or less dccurrent to the short petiole. 



We have of this fine species a specimen representing a small leaf 

 nearly entire on the border and with the trilobate form scarcely defined. 



The supposition that these leaves could be referable to Credneria is 

 contradicted by the short petiole, besides the other differences indicated 

 in the introduction. 



Platanus Eewberriana, Heer, Cret. Flora, p. 72, PL VIII, figs. 2, 3; 



PL IX, fig. 3. 

 Leaves of medium size, thickish, palmately three-lobed, either tapering 

 to a point from the lateral lobes upward, or without lobes and ovate ; taper- 

 pointed, broadly cuneate to the base, equally dentate; nervation trifidfroma 

 little above the base ; secondary veins close, numerous. 



Platanus diminutiva, Lesqx., Cret. Flora, p. 73, PL VIII, fig. 5. 



Leaf small, thick, half round from the middle to the base, narrowed to an 

 obtuse point ; borders entire, undulate; nervation trifld from above the 

 base ; nerves thick and irregularly inflated. 



As remarked already, this may be a diseased leaf of one of the for- 

 mer species. 



URTICINE^. MORE^L 



Ficus Halliana, Lesqx., Cret. Flora, p. 68, PL XXVIII, figs. 3 and 9. 



Leaves subcoriaceous, very entire petioled, broadly lanceolate, gradually 

 narrowed to a long acumen, more rapidly narrowed and rounded to the 

 petiole, nervation pinnate; lateral veins close, straight on an acute angle 

 of divergence, parallel, numerous.
