More often, however, spHtting of the original five staminal rudiments occurs, producing a larger number of stamens (fig. 52, B) which are free or united in bundles, or monadelphous at the base.

Longitudinal sections through the ovary of M. violaceum in three successive stages, shewing alteration in position of the placenta during development; st, young stamen. (After Eichler.) in the showy Mesembryanthemums, outer series of members resulting from this spHtting become petaloid, forming a showy corolla-hke series (fig. 52, D). The superior or inferior pistil consists generally of three to five united carpels, with a corresponding number of ovary-chambers , in the inner angle of which are borne rows of anatropous to campylotropous ovules. In some species of Mesembryanthemum the placentas, originally axile, become, through unequal growth of the ovary,.
