Monochrome Monday could have been a Throwback Thursday as it’s a shot from way back in my archives. Taken in Cheshire, England in the early 1980s when I used to keep a camera loaded with black and white film in my bag.
The upper leaf of this Hart’s-tongue Fern is lying upside down. It’s showing the sori that produce the spores used for reproduction.
It’s known as Hart’s-tongue Fern because the shape of the leaves resembles the tongue of a Hart, a male Red Deer.
