Meanwhile, a crescent shaped nectary lies at the base of the gynophore. Meanwhile, a crescent-shaped nectary lies at the base of the gynophore. As the fruit ripens, a stalk (or gynophore) develops. Capparaceae generally have a gynophore, sometimes an androgynophore, and a variable number of stamens. Occasionally, the gynoecium is born on a stalk, called the gynophore, as in "Isomeris arborea". A single gynophore protrudes from amongst the stamens in the open flower.
