HOW PLANTS ARE PROPAGATED. 
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 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 through 
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 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 Silique , the Silicle , 
and the Pyxis. 
240. A Silique (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 silique Capsules, opening. 
not much longer than broad. Fig. 215 is the silicle of 
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 . p Y xie. 
classed under the heads of Aggregated, Accessory, and Multiple fruits.
