The Chorna, Chyornaya[a] or Chorhun (Ukrainian: Чорна, Chorna, Russian: Чёрная, Chyornaya, Crimean Tatar: Çorğuna), which translates from the Ukrainian and Russian as "Black River", is a small river in southern Crimea. It is 34.5 km long.
The Chorna River begins in the Baydar Valley northeast of the small town of Rodnikivs'ke (44° 28' N 33° 51' EG), just west of which it flows into a reservoir. From there it continues in a westerly direction to the town of Inkerman (Belokamensk) where it enters the Bay of Sevastopol, on the southwest coast of the Crimean peninsula.
Inkerman was a key location during the Crimean War of 1853–1856 and the Chorna lends its name to the Battle of Chernaya (Chyornaya) River of 1855.
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.
