The pistil has its three parts, ovary, style, and stigma, very distinctly marked. The stigma consists of four long lobes, which curl outwards after the flower opens. The style is long and slender. The examina- tion of the ovary requires much care. You will get the best idea of its structure by taking one which has , just burst open, and begun to discharge its seeds (Fig. 41). The outside will then be seen to consist of four pieces (valves), whilst the is occupied by a slender four-winged col- umn, (Fig. 42), in the gi'ooves of which the seeds are compactly arranged. The pistil thus consists.
