Dr}- fruits which are indehiscent: Samara, an indehiscent, one-seeded fruit provided with a wing. In the Ash, the wing is tenninal; in the Elm, tlie wing surrounds the body of the pericarp; and the Maple fruit is a double samara or pair of such fruits. Achene (figures 81-88), a general term for all one-seeded, dry and hard, seedlike fruits. The best examples are the fruits of the Butter- cup, Anemone, Clematis and Avens. The style sometimes remains on the fruit as a long and feathery tail (Dandelion, figure 85), and in others merely as a short hook (Buttercup, figures 86 and S7). In the Compositae (Simflower faniily) the tube of the calyx is joined with the surface of the ovary, and its border or upper edge appears as a crown or cup, or a set of teeth or of scales, or very often as a tuft of bristles or hairs, called the pappus (figures 82-84,88). Utricle, a dry achenelike fruit with a thin and bladdery loose pericarp, like that of the Goosefoot (Chenopodium). Caryopsis oi- grain, differs from the achene in having the seed completely filling the cell and its thin coats fimily consolidated throughout with the very thin pericarp. This term is applied to the fruits of the grass family, including Indian com and all other cereals. Nut, a hard one-celled and one-seeded, indehiscent fruit which finds its best examples in the fruit of the Hazel, Beech, Oak, Chestnut etc. The smaller nutlike fruits of the Borrage family and of the Mint family are usually called Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original
