The fruit is dried or processed in water to remove the skin, cleaned, and bagged for shipment and use. The taxonomy of Coffea is confused, but doubtless the three previously mentioned species are the most important. There are also many botanical varieties, mutants. and cultivars. There are usually five long stamens on short, curving filaments and a long style with a two-part stigma. The stamens are attached to the corolla between the lobes so that the anthers are about the height although not necessarily close to the stigma.
Pollen is shed immediately after the flower opens, and the stigma is immediately receptive.
Nectar is secreted at the base of the tubular corolla, but accessible to honey bees and many other insects. Both nectar and pollen are attractive to many kinds of insects. On sunny days, the flower generally opens early in the morning and pollen shedding starts soon afterwards. The pollen is produced in comparatively small quantities and is not sticky. If the day is cloudy, the flower may remain closed but self-pollination can occur within the flower.
