(P, N, p, n, X I I o.) Samolus, anatropous with the hilum basal - together with the method of dehiscence of the capsule and the relative position of the ovary.
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.
These may be taken as the three types of ovule; but there are various intermediate forms, such as semi-anatropous and others.
- Anatropous ovule of Dandelion (Taraxacum), nucellus, which is inverted, so that the chalaza ch, is removed from the base or hilum h, while the micropyle f is near the base.
The sporangium is attached to the enlarged distal end of its pedicel, from which it hangs down, so as to suggest an anatropous ovule on its funiculus.
