In the silence of winter, the coming explosion of spring and summer life is being prepared in secret.
Let’s have a look to polypody to see the sporangia that are maturing.

Under the microscope here are the spores, beans like, protected by the membrane of sporangium which has a specific structure like a zip. After warmer days which will cause deshydratation this structure will lead to the opening of the sporangium and the realease of spores. Then the cycle will go on:
The name Polypodium comes from the Greck poly « numerous », and podion « small foot » after the small « roots » of the rhizoma.
Polypody has traditional uses in cooking for its aroma and sweet taste close to liquorice, and in herbal medicine as a purgative and vermifuge.
I wish you a 2018 year as wonderful, lively, sweet, full of hope and abundance than this tiny little fern.
