Hibiscus is a great flower to photograph. The contrast between the green sepals and bracts, showy red petals (this particular variety), deep red pistils surrounded by bright yellow stamens make a great study in contrast especially against a dark background. You may not enjoy the botany below, but I’m sure you’ll agree that nature truly offers a marvelous spectacle in the microscopic.

A fully open hibiscus flower
We all learned in school botany (well some of us!) about the various parts that make up a flower. Generally, flowers have 3 components –
Calyx – made up of sepals that protect the bud in infancy and form the base of the flower
A hibiscus bud showing bracts and the calyx (which are both modified leaves!)
Corolla – made up of showy petals that encase the reproductive organs

Reproductive parts (Corolla, Stamen) that are in turn

Stamen – that make up the male reproductive parts – in turn made up of the filament that holds up the pollen sac or anther. The anther releases pollen when open.

Pistil – The female reproductive parts of a flower. These are also made up of three components
Ovary – that finally forms the seed after fertilization
Style – a stalk above the ovary
Stigma – the farthest extend of the female part of the flower which receives the pollen for fertilization. This is usually sticky and allows pollen to attach.

The pollen in the above picture look spherical, don’t they? But in the picture below, which is a crop of the above, you can see that the pollen grains are spiky, thereby allowing them to stick to the stigma surface.

Well, that’s my botany lesson! Thanks for stopping by….
