The Nappstraum Tunnel (Norwegian: Nappstraumtunnelen) is an undersea road tunnel in Nordland county, Norway. The 1,776-metre (5,827 ft) long tunnel is located on the European route E10 highway, connecting the islands of Flakstadøya (in Flakstad Municipality) and Vestvågøya (in Vestvågøy Municipality). The village of Napp lies just south of the west entrance to the tunnel. The tunnel opened on 11 July 1990 to replace an old ferry connection that ran between the two islands. The tunnel reaches a depth of 63 metres (207 ft) below sea level and the maximum road grade of the tunnel is 8%. The tunnel had a toll on it until 2003 when the debt for the tunnel was paid off.[1]

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.
