This species is very close to Ficus woolsoni Newberry, which is a much 

 less elongated comparatively broader leaf, often with a cordate base in 

 consequence.

FlCUS CECILENSIS n. Sp. 



Plate LVIII, Fig. 4 



Description. Leaves of medium size, broad-lanceolate in general out- 

 line, with a narrowed but bluntly pointed tip and a somewhat more gradu- 

 ally narrowed, pointed base. Length about 13 cm. Maximum width, in 

 the middle part of the leaf, about 3.75 cm. Margins entire. Texture sub- 

 coriaceous. Petiole very stout, its length unknown. Midrib very stout 

 and prominent. Secondaries thin, about seven alternate pairs; they 

 diverge from the midrib at irregular intervals at angles of about 40, 

 curving upward, camptodrome. Tertiaries thin, well marked, at approxi- 

 mately right angles to the midrib, forming large, quadrangular, usually 

 transversely elongated, areoles. 



The generic reference of this new form is not certainly determined, as 

 it partakes of the features of lauraceous, ericaceous, and rhamnaceous 

 leaves as well as those of the extensive genus Ficus. It is readily distin- 

 guishable from the species of the latter with which it is associated.
