 quality. The fruit varied to some extent in form and substance, apparently 

 Including fruit of more than one tree. The seeds were not excessively large 

 and completely filled the seed cavities." (H. R. Fulton.)

54521. Melicocca bijuga L. Sapindacefe. Mamoncillo. 



'■ No. 3. A single seed collected September 17, 1921. From a tree of 

 mamoncillo on the place of Samuel Lewis on the Sabana. Mr. Lewis's 

 son sold this year $.j5 worth of fruit from this tree. The fruit of this seed- 

 ling is one of the most delicious I tasted in Panama. There was only 

 one fruit hanging on the tree. Apparently nothing has been done in the 

 way of selecting this excellent fruit, which has an exquisite flavor but 

 has the handicap of very fine silky fibers, which are attached to the 

 seeds themselves and are rather annoying to one not accustomed to 

 them. It is quite possible that this objectionable feature could be elimi- 

 nated by selection."
