[11] Hesperantha has a spreading style branch. The ovary often supports a long style, topped by a stigma. Ovary: It is the ductless reproductive gland that holds a lot of ovules. Most stigmas are trap pollen with hairs and other surfaces. It is the sticky bulb that you see in the center of flowers and is the part where the pollen lands and starts the fertilization process. Some plants that separate male and female flowers (monoecious angiosperms) have been found to retain their stigmas in the functionally male flowers but to delay the maturation of these stigmas. Ovary. Stigma can play an active role in pollen discrimination and some self-incompatibility reactions, that reject pollen from the same or genetically similar plants, involve interaction between the stigma and the surface of the pollen grain. A pistil may have several carpels. In the subapical pattern the style arises to the side slightly below the apex.
