Balta Sound is a sound (inlet) on the east coast of the island of Unst in the Shetland Islands, Scotland. The sound is sheltered from the North Sea to the east by the uninhabited island of Balta.
The settlement at the west of the sound is Baltasound.
On 12 March 1917, the World War I British E-class submarine HMS E49 was heading out of Balta Sound on patrol when it struck a naval mine laid by German U-boat SM UC-76. It was sunk in the channel between the islands of Huney and Balta with the loss of the entire crew. The site of the wreck is now designated as a war grave.

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.
