212. Classification of Fruits. — Fruits may be grouped 
under two heads, (1) fleshy and (2) dry fruits. Dry fruits 
are of two kinds, (1) those that open, dehiscent (de-his's’nt) 
(Latin, dehiscere, to open) fruits, and (2) those that do not. 
open, indehiscent (Latin, in, not; dehiscere , to open). In- 
dehiscent fruits have been formed by the thin wall (pericarp, 
the wall of the ovary, matured) adhering closely to the seed, 
much as if a pod con¬ 
taining a single seed grew 
so firmly to it that it 
could not open. 
A grain of corn or wheat 
is a typical indehiscent 
fruit. The pericarp, 
though very thin, is hard 
and flinty, furnishing Z22.-s»u*^ thesW.nged Fku.t
