Above is an image of a Clivia miniata flower, with some of the parts labelled.
The short green stem carrying the single actual flower is the "Pedicel"
At the distal (outer) end of the pedicel is the "Ovary", which forms the future fruit, the berry.
From the top center of the ovary extends the "Style". At the distal end of the style is the trifid (three-lobed) "Stigma". The actual pollen receptors are at the distal (outer) ends of the three lobes of the Stigma.
The "Pistil" is comprised of the ovary, style and stigma.
There are 6 "Tepals" (petals and sepals). At the base (proximal end) of each tepal is attached a "Stamen".
The stamen is composed of a stem called the "Filament", and at the distal end (the tip) of the filament is the "Anther" or pollen sac.
When the pollen ripens, the anther opens and the yellow "Pollen" is exposed. This process is called "Anthesis."
