firm (the "core"). The nature of the fruit varies, according to 

 the thickness and hardness of the endocarp, being either a " berry" 

 or a "drupe" (see A and J5). When the endocarp is thin and 

 parchment-like, the fruit has the characteristics of a berry, each 

 of the 5 loculi generally present containing several seeds ; but when 

 this is hard the fruit resembles a drupe, only one seed is developed 

 in each loculus, and the number of the loculi is reduced to one or 

 two. There are nearly always 2 ovules in the loculi of the ovary, 

 but in Cydonia there are a large number in 2 rows. In the genera

 genera are distinguished mainly in accordance with the kind of 

 fruit and the number of ovules and seeds.
