235. A Follicle is such a simple pod which opens down one side only. The pods 

 of Peony, Columbine, and Marsh-Marigold (Fig. 210) are follicles. 



236. A LcsiIIllC is a jiod of a simple pistil, which splits into two 

 pieces. It is the fruit of the Pea or Pulse family. 

 Fig. 211 is a legume of the Pea, open, separated into 

 its two valves. 



237. A Capsule is the pod of any compound pistil. 

 When capsules open regidarly, they either split through Foiiicie. 

 the parlitions, or where these would be, as in the pod of St. John's- 

 wort (Fig. 212) ; this divides them into so many follicles, as it were, 

 which open down the inner edge : or else they split open into the 

 hack of the cells, as in the pods of the Lily, the Iris 

 (Fig. 213), &c. 



238. The pieces into which a pod splits are called 

 its Valves. So a follicle (Fig. 210) is 



one-valved ; a legume (Fig. 211), two-valved ; the cap- 

 sules in Fig. 212 and 213, both three-valved, &,c. 



239. Two or three forms of capsule have peculiar 

 names. The principal sorts are the Siliqiie, the Silicle, 

 and the Pyxis. 



240. A Siiique (Fig. 214) is the pod of the Cress 

 family. It is slender, and splits into two 

 valves or pieces, leaving behind a partition 

 in a frame which bears the seeds. 



241. A Silicle or Pouch is only a siiique 

 not much longer than broad 

 Shepherd's Purse ; Fig. 216, the same 

 with one valve fallen. 



242. A Pyxis is a pod which opens 

 crosswise, the top separating as a lid. 

 Fig. 217 shows it in the Common 

 Purslane ; the lid falling off. 



243. There remain a few sorts of 

 fruits which are more or less compound or complex. They may be 217. pyxis. 

 classed under the heads of Aggregated, Accessory, and Multiple fruits.
