The Spots on Ferns – SF Conservatory of Flowers, continued….

on

Ferns are one of my favorite plants. In fact, my very first Microcosmos post concerned the very same. At our Foldscope workshop at SF Conservatory of Flowers this past Saturday (original post here), we took a closer look at those spots you see on the underside of ferns, which are sori, the spore-producing components of the plant.

It was a pleasure to be in his company all day and learn so much about the natural world in all its microscopic details 🙂

Until next time!
