HOAV PLANTS ARE PROPAGATED. 



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

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

 23 G. A Legume is a pod 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 regularly, they either split iJiroiigh 

 the partitions, 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 Vahes. 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 Siiiqae (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 sihque 

 not much longer than broad 

 Shepherd's Purse ; Fig. 21 G, the same 

 with one valve fallen. 



242. A Pyxis is a pod which opens 

 crosswise, the top separating as a lid. 

 Fio-. 217 shows it in the Common 

 Purslane ; the lid falling off. 

 "'^ Silicle. ^ 243. There remain a few sorts of 



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

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