Those of the specimens cited which have ever been determined specifically were 
referred to Ficus radula and F. radulina. From the latter the present species is clearly 
distinct in its glabrous branches. Ficus radula is not known at present in Mexico 
except from Yucatén. Ficus mexicana differs from it in having gradually acute or 
acuminate leaf blades, but it may not be sufficiently distinct to rank as a species. 
Specimens reported as Ficus radula by Liebmann! from Punta de San Augustin, 
Oaxaca, and Hacienda de la Laguna, Veracruz, are probably F. mexicana. 
Some variation is exhibited by the present series of specimens. In Rose’s no. 
1897, from Tepic, the leaf blades are very thick and are sometimes slightly lustrous 
on the upper surface, and the receptacles are long-stipitate. In Nelson’s no. 4361, 
from Marfa Madre Island, the stipules are longer than in any of the other specimens. 
The specimen collected by Eisen has very narrow blades. 
Miquel’s original specimens were without fruit, but his description of the vegetative 
characters agrees well with the present material. The grounds for his statement that 
the leaves of F. mexicana are narrower than those of F. anthelmintica, with which he 
compares it, are not easily understood, for judging from his own descriptions of both 
species the proportions of the leaf blades seem to be practically the same. 
The present species is one of the strangler figs. It is very abundant on the coastal 
plain of Tepic and southern Sinaloa.

Large or small tree; branches brownish gray, the young ones ferruginous, at first 
sparsely puberulent but soon glabrate; stipules lance-triangular, 10 to 15 mm. long, 
long-attenuate, minutely puberulent or glabrous; petioles stout, 0.6 to 2.8 cm. long, 
glabrous or nearly so, ferruginous or grayish, canaliculate; leaf blades oblong, obovate, 
obovate-oblong, or oval, usually broadest above the middle, 8 to 16.5 cm. long, 3.5 to 8 
cm. wide, narrowed to the obtuse or acutish, 5-nerved, subemarginate base, rounded or 
very obtuse at the apex and usually abruptly short-acuminate, the acumen obtuse or 
acutish, thin-coriaceous, pale green, subscaberulous above, scaberulous beneath, the 
lateral veins very prominent, 7 to 12 on each side, divaricate-ascending, subarcuate, 
anastomosing to form a submarginal vein, the veinlets prominent, closely or laxly retic- 
ulate; peduncles solitary, about 5 mm. long, stout, scabrous; involucre very small, 
trilobate, the lobes broadly rounded; receptacles subglobose, 1.5 to 3 cm. in diameter 
scabrous; ostiole very small, closed by numerous brown scales.
