Let's make some more!

     Camu camu, along with all plants in the Angiosperm group, reproduces sexually and involves male and female organs.  The female structures are the stigma, style, and ovary.  The stigma is the sticky portion of the pistil that captures pollen.  The pollen then moves down the long style into the ovary, which is composed of one or more ovules and is responsible for housing the eggs.  The male parts involved are the filament and anther.  The filament supports the anther which is responsible for storing and producing pollen.  The transfer of pollen from an anther to a stigma is pollination.  Many things can aid in pollination such as wind, water, insects, birds, and other mammals.  After pollination, one nuclei of the pollen grain forms a tube down through the style to the ovary.  The second nuclei travels down the tube and splits into two sperm nuclei that fertilize the egg.  Ultimately, the endosperm (stored fruit) is formed, covering and protecting the seed.
   The Camu camu plant requires specific conditions to reproduce.  More specifically, insects are needed to pollinate the flowers.  Although wind may still affect some pollination, studies have shown that bees are the most important pollinators and are attracted by the fragrance and nectar of the flowers (the small flowers of Camu camu bush have waxy white petals and an exquisite aroma). 
    The most common visitors to Camu camu are the stingless bees Melipona sp. and Scaptotrigona postica.  Actually, pollination by bees is the dominant method of pollination in the family Myrtaceae.
