The single but bilobed stamen develops from a primordium sunken within the dorsal flower pit, through elongation until it is elevated above the surface of the pit. When it dehisces, white pollen grains are visible, ~ 10 15 microns iin diameter. The stamen appear to be delayed behing the pistil in development, suggesting the possibility of outbreeding.
