Greenhouse Beauties

These bell shaped flowers fascinated me.  They were growing from a tropical plant in the greenhouses at UNCC.  The main part of the plant was full of stems but not densely formed.   The buds look like fragile single colored balloons and then they appear to open and variate in color.   A male pollen stem descends from  the balloon's center with female receptors all around the center stem.  Seeds then form as insects transfer pollen from the male to female appendages .  The seeds then drop off with the help of gravity making the plant hardier and more dense with time.
