SPECIMENS OF FRUIT. 



This pericarp is a univalve consisting of but one 

 valve or piece, and is called a follicle or bag. The 

 seed grows on the receptacle or the margin of the 

 suture ; and the pericarp bursts and discharges its seeds, 

 as seen in the cut, and as with the periwinkle and milk 

 weed. 



This cut represents a drupe or drupa, a stone fruit with 

 a fleshy or pulpy pericarp, without valves. The stone has 

 a seed or kernel, as with the plumb, cherry and peach. 

 The nut is a bony fruit with one cell generally, but it has 

 no fleshy pericarp as with the last. Its exterior envelop 

 is hard, with valves, as with the walnut, or membranous 

 as with the hazel-nut. With the acorn the envelop is but 

 partial. 



The Bacca, or berry, is a succulent fruit, as elsewhere 

 noticed. It never opens by valves, like the capsule : the 

 currant and gooseberry are examples. This and the 

 last cut show the fruit divided with the kernel and seeds 

 within. 



A compound berry is here shown composed of many small 

 berries or grains, each with a seed. 



This is a pome ; a fleshy pericarp without valves ; 

 but, unlike the two last, it has a capsule enclosing its 

 seeds. The apple, pear and quince are well known ex- 

 amples ; but these pericarps vary greatly in shape and 

 quality. 



The cone, or strobulus, is a hardened capsule, or seed 

 vessel, covered with scales, as in the pines, cypruses, &c. 



e alder and birch present an aditional capsule ; and in the 

 willow the capsule is bivalved and suspended by a stem dis- 

 tinct from the scales.
