With a popular flora, or an arrangement and description of common plants, both wild and cultivated. Botany. 78 now PLANTS ARE growing very thick and fleshy, makes the Avhole eatable part or flesh of the fruit in the haw and the quince. The real seed-vessels in the quince (Fig. 201), apple (Fig, 200), and the like, consist of the five thin, parchment- like cells of the core, containing the seeds. In the quince, all the flesh is calyx. But in the pear and apple the flesh of the core, viz. all inside of the circle of greenish dots which are seen on cut- ting the apple across (Fig. 200), belongs to the receptacle of the flower, which here rises so as to surround the real seed-vessels. Cutting the apj^le lengthwise, these dots come to view as slender greenish lines, separating what belongs to the core from what be- longs to the calyx: they are the vessels which in the blossom belong to the petals and the stamens above. In the haw, the cells become thick and stony, and so form a kind of 226. StOIie-Fruit or Drupe. Plums, cherries, and peaches (Fig. 202) are the commonest and best examples of the stone-fruit. It is a fruit in which the outer part becomes fleshy or pulpy, like a berry, while the inner part becomes hard or stony, like a nut. So the Stone (or Putamen, as the botanist terms it) does not belong to the seed, but to the fruit. It has the seed in it, Avith coats of its own. 227. Dry Fruits are those that ripen without flesh or pulp. They are either dehiscent or indehiscent. Dehis- cent seed-vessels are those which split or burst open, in Forne regular Avay, to discharge the seeds. Indehiscent ^ seed-vessels arc those that remain closed, retaining the seed until they grow, or until the seed-vessel decays. All stone fruits and fleshy fruits are of course indehiscent. 228. The sorts ot indehiscent dry fruits that we need to distinguish are the AJcen
