The ovary contains one or more ovules borne on a placenta, which is generally some part of the ovary-wall.
The placenta is discoidal and deciduate.
The ovule appears at first as a small cellular projection from the placenta.
More remarkable still is the development of a small allantoic placenta.
There are five, or sometimes fewer, carpels, which unite to form an ovary with as many chambers, in each of which are one or two, rarely more, pendulous anatropous ovules, attached to the central column in such a way that the micropyle points outwards and the raphe is turned towards the placenta.
