3. AN ON A Linnaeus 



Small trees or shrubs. Flowers solitary or fascicled, terminal or leaf- 

 opposed. Sepals 3, small, valvate. Petals 3 or 6, valvate in 2 series or 

 the inner series wanting, the outer ones 3-angled or broad and flat, concave 

 at the base, the inner ones quite different from the outer. Stamens 

 numerous; anther-cells narrow, dorsal, contiguous, top of the connective 

 ovoid. Ovaries many, subconnate; style oblong; ovule 1, erect. Ripe 

 carpels confluent into a many-celled, ovoid or globose, many-seeded, fleshy 

 fruit. (Said to be derived from the Malay name menona.) 



Species many in Africa and America, several other species introduced 

 from the latter region into other tropical countries for the sake of their 

 edible fruits; 3 species in the Philippines, all introduced from Mexico at 

 an early date. 



1. Outer 3 petals broadly ovate-cordate, about 3 cm wide, the inner 3 also 



large; fruit prominently echinate 1. A. muricata 



1. Outer 3 petals narrowly oblong, less than 1 cm wide, inner 3 minute or 

 wanting. 

 2. Flowers 2 or 3 together on lateral peduncles; leaves long-acuminate; 



fruits smooth, reticulate ^. 2. A. reticulata 



2. Flowers solitary; leaves obtuse or acute; fruit roughened by the 

 rounded ends of the carpels 3. A. squamosa 



* 1. A. MURICATA L. Guanabanos (Sp.-Fil.) ; Soursop. 



A tree 6 to 7 m high. Leayes oblong-obovate to' oblong, 7 to 20 cm

 introduced at an early date and now widely cultivated in the Archipelago. 



* 2. A. RETICULATA L. Anonas (Sp.-Fil.) ; Custard Apple. 



A tree 10 m high or less. Leaves oblong to oblong-lanceolate, acuminate, 

 20 cm long or less, glabrous; petioles 1 to 1.5 cm long. Flowers greenish- 

 yellow, fragrant, 2 to 2.5 cm long, 2 or 3 together on lateral peduncles.
