SAFFORD—CLASSIFICATION OF ANNONA, 47 
umbonate protuberances, as shown in figure 55. Mature seeds collected by 
Pringle in the Barranea of Guadalajara in 1902 are very different from 
those of Annona cherimola, being truncate or obpyramidal in form without a 
caruncle at the base, and having the testa quite smooth and nutlike, thicker 
than those of the common edible custard apples and similar in texture to the 
seeds of Annona diversifolia. They differ so much from those of all other 
species of Annona that they alone would be sufficient to identify this species. 
According to Doctor Palmer’s notes, the fruit is edible either raw or cooked. 
A sweetmeat is made by boiling it with sugar, together 
with the fruit of the tejocote (Crataegus mexicana).
