186 DESCRIPTION OF SPECIES. 



Ilex inicrophylla, sp. nov. 



Leaves small, coriaceous, obovate or spatulate, rouiuled and denticulate at the 

 apex, narrowed to a short broad petiole; secoudary nervation obsolete. 



The leaf, 2i centimeters long, 7 millimeters broad in the upper part, 

 is gradually narrowed to a petiole 7 millimeters long. Its affinity, which 

 is close indeed, is with Ilex amhif/ua, Ung., "Syllog.," ii. p. 14, pi. iii, fig. 29, 

 from which it differs merely by the gradually narrowed base of the leaf 

 and the longer petiole.

Ilex inaculata, sp. nov. 



Plate XLIV, Fig. 5. 



Leaves coriaceous, obovate, obscurely and irregularly creuulate, narrowed to the 

 petiole; medial nerve narrow, the lateral at a broad angle of divergence, a little curved 

 in traversing the blade, efifaced toward the borders. 



The leaf is badly preserved; its surface is maculated or gnawed by 

 parasite hypophylles or insects. Its shape and thick consistence appear 

 to refer it to this genus.

Plate XXXVIII, Figs. 2-5. 



Leaves coriaceous, short-petioled, obovate, abruptly acuminate, irregularly acutely 

 dentate from near the base; secondary nerves at a broad angle of divergence, slightly 

 curved in passing to the borders, entering the teeth directly or by branchlets; inter- 

 mediate tertiary veins short, anastomosing with uervilles in the middle of the areas. 



The leaves are very variable in size (from 12 millimeters long to nearly 



6 centimeters, and 5 millimeters to 2 centimeters broad); the petiole is 



thick and short (6 millimeters long); the teeth turned outside, sharply
