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. 5 
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 Capsnle is the pod of any compound pistil. v 
When capsules open regularly, they either split through Follicle. 
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 ¢nto the 
back of the cells, as in the pods of the Lily, the Iris 
(Fig. 213), &e. : AN 
an 238. The pieces into which a pod splits are called 2 
ica its Valves. So a follicle (Fig. 210) is le 
one-valved ; a legume (Fig. 211), two-valved ; the cap- 
sules in Fig. 212 and 213, both three-valvgd, &e. 
239. Two or three forms of capsule have peculiar 
names. The principal sorts are the Stlique, the Stlicle, 
and the Pyzis. 
240. A Silique (Fig. 214) is the pod of the Cress 
, family. It is slender,.and splits into two

in a frame which bears the seeds.

not much longer than broad. Fig, 215 is the silicle of 
és Shepherd’s Purse; Fig. 216, the same

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.
