SEEB VESSELS. 203 



Pome, Fig. 93. The Pome or Apple is a pulpy seed 

 vessel, without valves, and enclosing a capsule. The 

 Apple and Pear are examples. 



Berry, Fig. 91. This is a pulpy seed vessel, contain- 

 ing one or more seeds enveloped in the pulp. It be- 

 comes soft and juicy, as it approaches maturity, in 

 which respect it differs from the capsule ; and though 

 when young it is sometimes difficultto distinguish them, 

 the distinction is made with ease when they have be- 

 come fully ripe. The Orange and Lemon are regard- 

 ed as berries with a thick coat ; and the Melon, Cu- 

 cumber, and Gourd, are usually considered as varieties 

 of the Berry ; though Gasrtner separated them, and 

 applied a different name, (Pepo.) 



Externally the Apple and Berry are alike, but in the 

 interior of the latter we find no capsule to separate 

 the seeds from the pulp of the fruit, they being imbed- 

 ded in its substance as in the Gooseberry and Currant. 

 Such is the texture and arrangement of most berries 

 but in the Linnaea and Trientalis the berry is dry and 

 juiceless, and is distinguished from the capsule only 

 by its want of valves. When several berries each 

 with one seed are united together as in the common 

 Raspberry, they constitute the compound berry. 

 There are several spurious kinds of berries whose pulp 

 is not properly a part of the fruit, but originates from 

 some other organ. Thus in the Mulberry as well as 

 in the Strawberry Spinach, the catyx after flow- 

 ering becomes coloured and very juicy, investing 

 the seed like a genuine berry. 



In the Juniper a few scales of the fertile Catkin be- 

 come succulent and coalesce into a globular berry with 

 thr^e or more seeds, and in the Yew ; some have 

 thought it a calyx, others a peculiar kind of receptacle.
