. A manual of the medical botany of North America [microform]. Botany, Medical; Botany; Botanique médicale; Botanique. Fio. 52.—A polyscpnlous calyx. Fio. 53.—A mono- or gamo- sepaloug ciilyx. Fio. 54.—IrreRiilnr (pptnloid) calyx of aconite. When the sepals are distinct the calyx is termed polysepalous (Fig. 52) ; when they arc united it is termed mono- or gamosepalous (Fig. 53). The monosepalous calyx is commonly more or less cut or divided from the mai'gin downward ; in such cases the undivided portion is termed the tube, the free border the limb, and the point where these meet the throat. The separate portions of the limb are often spoken of as lobes, or teeth. It should be borne in mind, however, that in the earl}' stage of the development of the calyx the sepals are always distinct ; hence a gamosepalous calyx is one in which the sepals have grown together, in whole or in part, its teeth or lobes alone remaining to show the number of the original sepals. The calyx is regular when its sepals are all alike (Figs. 52 and 53) ; irregular when some of them are different in form from the others (Fig. 54). It is deciduous when it falls away after the fertilization of the flower ; caducous when it falls as the flower expands ; persistent when it remains until the fruit matures. Tlie corolla is the inner floral envelope. It is commonly colored, and in this respect is in strong contrast with the calyx. Its separate leaflets are termed petals, and, like the sepals, they may be more or less.
