Dura Den is a small, 3 km-long wooded gorge that is located near Cupar in northeastern Fife, Scotland. This narrow cleft follows a course between the villages of Kemback to the north and Pitscottie to the south. A small stream, named the Ceres (or Kame) Burn, follows the course of this gorge and this flow includes small waterfalls near the midpoint. Historically the Ceres Burn was used to power jute spinning mills
Around 1859, the geologist and Newburgh minister John Anderson discovered what turned out to be extensive sandstone deposits of ganoid fossilized fish in this area.
The Dura Den Wood occupies an area of 4.25 acres (17,200 m2). The woods include ash, oak, and hazel.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
