DESCRIPTION OF SPECIES. 177 



passing- al)ove alono- tho borders. Tlic lower pairs of secoudaines are at a 

 more acute angle of divergence than those above, which curve along- the 

 boi-ders in simple areoles; the thin nervilles are at right angles to the nerves, 

 flexuous and running downward. The leaf is G.S"" long, 2"'° broad at the 

 middle, the base being destroyed. 



Except in its nervation, which is that of the genus, the species has no 

 nearer relative than the next.

Ilex papillosa, sp. nov. 

 PI. XXIX, Figs. 9, 10; PI. LVIII, Fig. 3. 



Leaves coriaceous, lanceolate, sharply acuminate, and acutely dentate 

 on the borders; teeth turned upward, papillose at apex; secondaries very 

 oblique, some entering the teeth, some curving in areoles near the borders; 

 nervilles strong, at right angles to the nerves, broken at the middle by 

 transverse veinlets forming a large, qua(h'angular or polygonal areolation. 



The two fragments (PI. XXIX, Figs. 9, 10) which are preserved ujjon 

 the same piece of stone, represent a leaf of about the same size as that of 

 the preceding species. The apex is formed by a sharply acuminate tooth 

 similar to those of the borders, which are long, turned upward and marked 

 at the acute apex by a small, round black point or knob. The secondaries, 

 which are at an angle of divergence of 20° to 2.5°, are mixed, generally 

 craspedodrome, or some of the intermediate ones cam})toch'ome, the nervilles 

 and areolation deeply marked. 



As far as can be seen from the small fragmentary specimen (PI. LVIII, 

 Fig. 3), whose surface is etfaced by erosion, it represents the same species. 

 The papill;^ of the teeth are scarcely marked; the leaf is of thick texture; 

 the nervation only preserved for the secondaries, no trace of areolation 

 remaining visible. 



The species has by its nervation and the division of its borders a degree 

 of affinity to /. dri/andne folia Sap.,' but greatly differing in the direction and 

 in the distribution of the teeth.
