Calyx of three or five persistent sepals, strongly imbricated. Petals as many as the sepals, convolute in asstivation. Stamens as many, as the petals, and usually with as many intermediate teeth representing an abortive series (Fig. 423), all united at the base into a ring, hypogy-. nous. Ovary with as many styles and cells as there are sepals, each cell with two suspended ovules ; the cells in the capsule each more or less divided into two, by a false par- tition which grows from the back (Fig. 750) ; the spurious cells one-seeded.
