daceae, which is called ‘‘ genipe’’ in Porto Rico. The fruit of genipa is from 4 to 
6 inches (10 to 15 centimeters) in length and oval inshape. The skin is somewhat 
leathery in texture and of a russet color, irregularly mottled with grayish. The 
section shows it to be two-celled. The rind and the pulp, in which the seeds are 
embedded, are used in the preparation of one of the refreshing drinks which are 
such a feature in Porto Rico. The ‘‘jagua”’ is also occasionally eaten, but can 
scarcely be recommended. It has somewhat the flabby texture and much of the 
taste of dried apples; according to Schumann, it contains large quantities of tannic 
acid. 
It reaches a height of 50 feet (15 meters), with a long, rather straight trunk, 
from 15 to 20 inches (37 to 45 centimeters) in diameter. It furnishes a rather 
soft, light wood that is, however, strong and resistant, flexible, and fibrous in 
texture. The color is uniformly whitish, tinged with a light reddish brown. It 
resembles the ash and possesses also its properties. It is very suitable for boxes 
and for any work where strength and elasticity are needed. The rims of sieves 
and shoe lasts are made of this wood. The military authorities of San Juan used 
it for ammunition chests and for hoops to barrels. Specific gravity, 0.873.
