Anatomy of a Hibiscus – Part 2 (Extreme Macro)

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.

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

  • 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….

    1. Thanks Richert.. this was an experiment with extension tubes on the macro lens. I was surprised at how much detail I was able to see with them.. πŸ™‚

    1. Thank you! My blog is not a biology blog but a photo blog where in this instance I have tried to show details of the flower using high magnification photography.

  1. Hi Jawahar,
    I found your blog while looking for information on a Hibiscus flower.
    I am sorry, I should have asked first if I could use a small portion of your info, {none of your images were used}, and put your site information to my latest image.
    I also am now following since you have such wonderful images and information.
    Looking forward to seeing what you will present to us to view.

    1. Thank you. I can’t actually find the post and how you’ve used the information from my blog site. The message I get it that the site is deleted.

  2. My site is and the image I used some of your information on is called Pollinating!
