Casimiroa edulis La Llave & Lew.: Iztaczipotl, 
cochitzdpotl, sapote blanco, white sapote; C. Sapota 
Oerst.: matasano. 
These trees are grown in Mexico and Central America 
for their sweet fruits, which apparently vary in quality. 
A good account is given by Martinez (186). C. edulis, 
the sapote blanco, is Mexican in its present occurrence, 
while C. Sapota, the matasano, is largely Central Ameri- 
can. These distributions probably reflect their origins.

Chamaedorea Tepejilote Lichm., C. Wendland- 
iana (Oerst.) Hemsl.: Tepejilote, pacaya. 
At least one, and probably several, species of the small, 
attractive palm, Chamaedorea, are cultivated in southern 
Mexico and Central America for the young staminate 
flower clusters, which are used as a vegetable. ‘The un- 
opened inflorescence is said to resemble an ear of maize 
in appearance and, at times, in size. Standley (198) re- 
ports them to be quite palatable. Chamaedorea, like most 
palm genera, is in need of study, and the names given 
here are, at best, tentative. (81, 191, 192, 198*) 
Chenopodium Nuttalliae Safford (C. pueblense 
Reed?): Cuauhzonth, huauhtzonth, apazote. 
Though less well known than the species cultivated in 
South America, this Mexican Chenopodium was of some 
importance, as indicated by its present relict occurrence 
in cultivation in many parts of Mexico (159, 172). It 
now is used principally as a green vegetable (the unripe 
fruit clusters), though it may have been used to some ex- 
tent as a cereal, as are the South American species. C. 
pueblense Reed (58) was not distinguished from C. Nut- 
talliae by its author and may be the same species. C. 
Nuttalliae is closely related to C. Quinoa Willd. of the
