Rafael, Distrito de Pochutla, Oaxaca, Mexico, altitude 800 meters, May 14, 1917,

nate leaves and much larger flower heads.

stamens 2; bracts of the pistillate heads concrete, the exposed portion muricate 
and minutely puberulent. 
Type in the U. S. National Herbarium, no. 842612, collected at Cafetal Con- 
cordia (Cerro Espino), Oaxaca, Mexico, November 15, 1917, by B. P. Reko 
(no. 3590). 
Distinguished from all other species of the genus by the prickles of the 
branchlets, stipules, and leaves. The vernacular names are “ carnero” and 
“chirimoya.” Doctor Reko states that the fruit is edible and that the leaves 
are sometimes half a meter long.
