(b) Opposite the petals. THE PISTIL OR GYNCEOIUM. Parts. Cahi' : the pieces, distinct or combined together, which make up the whole pistil. The pistil is (ii) Simple, if it consists of one carpel only, as in Pea (Fis. los). (b) Compound, if it consists of two or more carpels, either separate from each other ((tpocarpuus) as in Buttercup (Fi^,^ 15'.)), or combined together (synvarpoiis) as in Fig. 100. When .several carpels are combined, the number is very commonly indicated by seams or sutures on tiio outside of the ovary. AVhether composed of one carjjel or several combined, the pistil may have the following parts : OvAKV: the lower swollen part, containing the ovule or ovules which dovolope into seeds (Fig. KJO), The ovary may be one-celled even when compound (Fig. Kil), or several-celled (Fig. KiO). In the latter case the separat- ing walls are called dissejuments, and the cells are often spoken of as Inculi (sing, ). Stvle : the narrow part above the ovary (Fig. IGO). A com- pound pistil may have several styles, as in Fig. Ifi2. Stigma : the moist roughish upper end of the style. This part differs from the rest of the pistil in having no skin or epidermis (Fig. KJ.'J). The stigma is (a) Capitate, if it forms a knob or button on the end of the style (Fig. 1G4). (b) Plumose, if of a feathery appearance as in grasses (Fig. 165). (c) Petaloid, if leaf-like and coloured, as in Iris (Fig. Fife'. Fife'. 1-
