ANONA 



AN ON A MURICATA L. Plate IV, fig. 2. Guabano; Soursop; Goyabano, 

 GuanabAno, Sp. Fil.; Guayabano, II: 



A small tree about 5 meters high, with oblong-ovate leaves 8-18 

 centimeters long. Fruit aggregate, fleshy, irregular, oblong- 

 ovate to conical, greenish, covered with soft scattered spines, 

 the flesh white, rather fibrous, subacid. Native of tropical 

 America. 



The ripe fruit possesses antiscorbutic properties, and a pleas- 

 ant acid taste, although the pulp is rather stringy with black 

 seeds scattered throughout. The juice bears a slight resem- 

 blance to pineapple in taste, and may be used as a refreshing 

 beverage. 



A fermented drink of agreeable taste not unlike cider is made 

 from the juice of this and the other species of anona in the West 

 Indies, where the fruits are plentiful. The fruit is one that 

 possesses possibilities of value if preserved or canned, as it is 

 excellent in salads and desserts and is available in sufficient 

 quantity.

 Sugar apple; Ates, Sp. Fil.; Atis, II.

 meters long, pale beneath. Flowers 1 to 3, opposite the leaves, 

 2.5 to 3 centimeters long. Fruit soft, fleshy, glaucous, aggregate, 

 irregularly heart-shaped, 7.5 to 10 centimeters long, tubercu- 

 late, the flesh sweet. Seeds numerous, dark brown. Native of 

 tropical America. The ripe fruit easily separates into segments
