A tree 4 m. tall or more, with white fragile wood and round 

 glabrous spiny branches. Leaves fascicled in the axils of the 

 spines, obovate-oblong, rounded at the apex or sometimes emar- 

 ginate, cuneate at the base, glabrous, shining, about 2.5 cm. long 

 and 9-10 mm. wide : panicle terminal, corymbose, much-branched, 

 its branches glabrous : capsule about i cm. long : sepals nearly 

 orbicular, about one fourth as long as the capsule : seeds oblong, 

 compressed, the margin membranous-winged, the inner surface 

 concave, the outer convex, brown, glabrous, the wings nearly en- 

 tire, emarginate at the apex and at the base ; episperm thinly 

 membranous, adhering to the endosperm which is thin and fleshy; 

 embryo included, straight, almost as long as the endosperm, com- 

 pressed ; cotyledons leafy, ovate, obtuse, cordate at the base, 

 fleshy ; radicle cylindric, somewhat acute, one third as long as the 

 cotyledons. 



The above description is drawn from the original in the work 

 of Humboldt, Bonpland and Kunth, cited above. I have seen no 

 specimens of this species, but its corymbiform panicle is unlike 

 that of any of the others. The type material was in fruit only, 

 and was secured at Puente de la Madre de Dios, at an altitude of 

 about 5.280 feet. This place is somewhere in the neighborhood 

 of Mexico City or Actopan, but it has not been possible for me, 

 up to the present time, to locate it more definitely. 



It is interesting to note here that this is the type of Fouquieria, 

 a monotypic genus at that time, which was based on Cantua fascic-
