Here are two cross sections
through the flower (at
top) and fruit (at bottom) of Princetonia.
Both of these specimens have 5 locules, although there can also be 3 or
4 present. In the top photo, the ovary
is sectioned in somewhat oblique cross section, such that it is cutting
through the receptacle at the left and through the locules at right.<> The small fuzzy things attached to the center of the
ovary
are the ovules: this plant has axile placentation and many ovules per
carpel.
<>Surronding the ovary
are numerous stamens. They look like
little butterflies, with each of the four pollen sacs extended out and
connected in the center. There is a petal or sepal to the outside. In the bottom photo, you
can see the extensive placental region in the central fruit axis and
numerous
well developed seeds in the locules.
