ESSENTIAL ORGANS—THE STYLE. 247 manner, so that its apex (as in reclinate' vernation, fig. 222 o) ap- proaches more or less the base. When the folding is slight, the style becomes lateral (fig. 416); when to a greater extent, the style appears to arise from near the base, as in the Strawberry (fig. 434), or from the base, as in Chrysobalanus leaco (fig. 435), when it is called basilar. In all these cases the style still indicates the organic apex of the ovary, although it may not be the apparent apex. The carpel sometimes becomes imbedded in the torus, which consequently forms an elevated margin round it; and then, if the style is basilar or lateral, it may adhere to a portion of the torus, on one side of the carpel, and appear to arise from it. This is seen in Labiatse (fig. 436) and Boraginacess (fig. 437), where the four carpels, 0, are sunk in the torus, r, in such a way that the common style, s, formed by the union of four basilar styles, seems to be actually a prolongation of the torus. When carpels are arranged round a central pro- longation of the torus, with which their united style is con- tinuous, the arrangement is called a gynobase (yuvij, pistil, /3aff/ff, base). It is well de- veloped in Ochnacese. In Ge- ^"S- *36. Fig. 43r. raniacesB there is a carpophore or prolongation of the torus in the form of a long beak, to which the styles' are attached. The form of the style is usually cylindrical, n;iore or less filiform and simple; sometimes it is grooved on one side, at other times it is flat, thick, angular, compressed, and even petaloid, as in Iris and Oanna. In Goodeni- aceae it ends in a cup-like expansion, enclosing the stigma. It may be smooth and covered with glands and hairs. These hairs occasionally aid in the application of the pollen to the stigma, and are called collecting hairs, as in Goldfussia; in Campanula t
