 some of them bear oval fruits, but only a few of these remain, 

 the greater part of them having apparently fallen off before

 instead of having the veins parallel, have them forking at a 

 very acute angle, and slightly netted, by the spreading branches 

 of the veins uniting with the others near them. This allies the
