ANONACE^E. 



Benth. et Hook. Gen. PL i. 20. 



Fruit and Seed. The carpels are generally numerous. 

 The ripe fruit is either dry and dehisces like a follicle with two 

 valves as in Anaxagorea ; baccate, one-celled and one-seeded as 

 in Polyalthia ; woody and one-celled with the seeds embedded 

 in pulp as in Monodora ; or fleshy and united into a large 

 multilocular indehiscent fruit as in Anona. The fruit is rarely 

 dehiscent in the Order, and the seeds are generally of large 

 size, sometimes arillate. There are one or two erect, anatropous 

 ovules in each cell with the raphe ventral, or the ovules are 

 numerous and arranged in one or two rows along the ventral 

 suture. In the species of Anona the ovules are solitary in 

 each cell, and the seed attains a large size, is broadly oblong 

 and more or less compressed laterally. The outer coat is 

 thick and corky or subwoody, while the inner one is in- 

 vaginated, i.e. dips deeply into the fleshy and copious endo- 

 sperm, making it ruminated. The embryo in the mature 

 seed is small and situated close to the hilurn, embedded in 

 endosperm. The ruminated character of the endosperm is 

 common to the Order. 



The seeds differ greatly even in nearly allied species. Thus
