Mystery Monday: What is this?

Mystery Monday: What is this? Not another alien from the movie Prometheus in all its 3D gory glory. It’s a scanning EM image of the under surface of a lavender leaf at a scale of 1/50th of a centimeter.

The globules are lavender oil, secreted from spiny glands known as trichomes. The spines also protect the leaf against pests and reduce water loss. The eye-like or elliptical structures with a narrow slit are the stomata or breathing pores.

The oil of Lavandula is used in perfumes, aromatherapy and to counter anxiety. Oddly, it also mimics female hormones. As such, use of lavender (and tea tree) oil is suspected to promote breast development in both boys and girls who are particularly susceptible to androgenic and estrogenic compounds.

    Wonder how those oil droplets hang on?

    some sort of surface tension?

  4. I’m going to take a magnifying glass out and look closely at my lavender plants. This is cool.

    I guess so. You can actually see smaller globules at the tips of some spines.

    Do report back if you see anything, Maureen Frost . But you’ll likely need a powerful microscope.

    Patrick Armstrong , I was going to reassure you that the condition only affects children, but a quick look up shows that it can happen to body builders who take anabolic steroids..some of the steroids are converted to female hormones!

    It’s what wikipedia says-

    Because sex hormone levels normally are low prior to puberty, young boys and girls particularly are sensitive to estrogenic and androgenic compounds. The discovery of the gynecomastia link in boys has led some researchers to suspect lavender and tea tree oils, which are present in various personal care products including shampoos and lotions, may also contribute to the increased incidence of early breast development in girls.
