150 REPRODUCTIVE ORGANS. CHAP. III. 



Cherry it is succulent, in the Strawberry it is 

 pulpy, in the Apple it is fleshy, in Staphyllea it is 

 membranaceous, in the Elm-tree it is leathery, 

 and in the Nut it is woody. But it is very seldom 

 of the same consistence throughout. For some- 

 times the outer part is soft and the inner part hard, 

 as in the Peach and Cherry ; and sometimes the 

 outer part is hard and the inner part soft, as in 

 the Filbert and Cocoa-nut; but sometimes both 

 parts are alike, as in the Pine Apple. From these 

 different modifications Gaertner institutes a division 

 of fruits into soft, hard, and mixed. * The Currant 

 is an example of the first; the Filbert of the se- 

 cond ; and the Peach or Apricot of the third. 

 .Covered or Some fruits are covered with a thick rind ; many 

 with a thin cuticle only ; and many are without 

 even that. The cuticle may be seen in succulent 

 berries ; and the rind or bark in the Orange and 

 Cocoa-nut. The bark is in general closely attached 

 to the interior part; but sometimes it is remote 

 from it and inflated, as in Scytalla chinensis. In 

 its exterior surface it is generally smooth and uni- 

 form, as in the Cherry ; or cottony, as in Peony ; 

 or scaly, as in Sago; or dotted, as in the Orange; 

 or perforated with holes, as in Artocarpus ; or 

 ribbed, as in the Melon ; or rough, as in Galium 

 aparine ; or set with tubercles, as in Onobrychus ; 

 pr with prickles, as in Canna indlca ; or with 

 thorns, as in Trapa. But it is often also exqui
