In indehiseent fruits the seed is liberated by the decay of the envelope, or bj' the rupturing of the envelope by the ger- minating seed. Indehiseent winged pericarps are known as samaras or key-fruits (consult Chapter XXII). Maple, elm (Fig. 93), and ash (Fig. 127) are examples. 288. PERICARPS.âThe simplest pericarp is a dry, one- seeded, indehis(ient body. It is known as an akene. A head of akenes is shown in Fig. 242, and the structure is explained in Fig. 191. Akenes may be seen in buttercup, hepatica, anemone, smartweed, buckwheat. 289. A 1-loculed pericarp which dehisces along the front edge (that is, the inner edge, next the center of the flower) is a follicle. The fruit of the larkspur (Fig. 243) is a follicle. There are usually five of th«se fruits (sometimes three or four) in each larkspur flower, each pistil ripening into 241. Chestnuts are ripened ovaries. They are borne in a prickly involucre.
