The elements of botany for The elements of botany for beginners and for schools elementsofbotany00gray Year: 1887 the papery pods arranged like a star in the core really belonging to the carpels. The fruit of the Hawthorn is a drupaceous pome, something be- tween pome and drupe. 355. Of fruits which are externally fleshy and internally hard the lead- ing kind is 356. The Drupe, or Stone-fruit; of which the cherry, plum, and peach (Fig. 375) are familiar examples. In this the outer part of the thickness of the pericarp be- comes fleshy, or softens like a berry, while the inner hardens, like a nut. From the way in which the pistil is constructed, it is evident that the fleshy part here answers to the lower, and the stone to the upper face of the component leaf. The layers or concentric portions of a drupe, or of any pericarp which is thus separable, are named, when thus distinguishable into three portions,— Epicarp, the external layer, often the mere skin of the fruit, Mesocarp, the middle layer, which is commonly the fleshy part, and Endocarp, the innermost layer, the stone. But more commonly only two portions of a drupe are distinguished, and are named, the outer one Sarcocarp or Exocarp, for the flesh, the first name referring to the fleshy character, the second to its being an external layer; and Putamen or Endocarp, the Stone, within. 357. The typical or true drupe is of a single carpel. But, not to multiply technical names, this name is extended to all such fruits when fleshy without and stony within, although of compound pistil, — even to those having several or separable stones, such as the fruit of Holly. These stones in such drupes, or drupaceous fruits, are called Pyrence, or Nucules, or simply Nutlets of the drupe. 358. Of Dry fruits, there is a greater diversity of kinds hav- ing distinct names. The indehis- cent sorts are commonly one- seeded. 359. The Akene or Ache- nium is a small, dry and indehis- cent one-seeded fruit, often so seed-like in appe
