Not illustrated. 1907 Excerpt: ...of growth which follow fertilization. The ripening ovary of this type becomes a simple fruit. In some cases, fertilization is followed by a modification of the end of the flower-stalk, producing a complex fruit, such as that of the apple, strawberry, blackberry, rose, pine, pineapple, Osage orange, etc. Fruits are usually classified with respect to their texture as (1) fleshy fruits, including stone fruits, and (2) dry fruits, and, with respect to their behavior when ripe, as dehiscent or indehiscent. Fleshy and stone fruits are indehiscent; dry fruits may be dehiscent or indehiscent. 133. Fleshy fruits are characterized by a thickening and softening of the wall of the ovary, by which it becomes juicy or fleshy. They comprise the berry, drupe, pepo, pome, and such multiple fruits as the fig and pineapple. In the berry, e.g., the currant, grape, gooseberry, tomato, etc., the whole tissue of the ovary is soft. In the drupe or stone fruit, apricot, cherry, peach, etc., the outer part of the wall becomes fleshy, while the inner hardens into stony tissue. On the other hand, the pepo has developed a hard rind upon the outside, while the inside is pulpy. The pome of the apple and pear resembles a berry, but the flesh is the modified calyx, the pistil being represented by the papery core. 154. Dry fruits are leaf-like, papery, membranous, or hard in texture. Indehiscent dry fruits, i.e., those that do not split open at maturity, are the achene, the nut, the samara, and the grain. The achene is a small seed-like fruit, such as is found in the buttercup, strawberry, sunflower, thistle, dandelion, etc. The nut is a fruit which possesses a hard stony wall, such as is found in the acorn, hickory, and walnut. The samara is an indehiscent fruit provided with a wing, e.g., ..
