An average fruit has from twenty to thirty tubercles, at first armel 
with a number of slender spines, which are deciduous in November ail |

The tubercles of the immature fruit are very prominent, but ait 
fruit ripens it increases considerably in size, becoming moré succulétt 
and as a result the tubercles become much less conspicuous, sometillt | 
entirely disappearing, leaving the fruit smooth save for the small brisle 
covered pulvini. The oval fruit when ripe is frequently two inché F 
long, and one and one-half inches in diameter, well filled with smo
