In the architecture of a ship, a companion or companionway is a raised and windowed hatchway in the ship's deck, with a ladder leading below and the hooded entrance-hatch to the main cabins.[1] A companionway may be secured by doors or, commonly in sailboats, hatch boards which fit in grooves in the companionway frame. This allows the lowest board to be left in place during inclement weather to minimize water infiltration.[2] The term may be more broadly used to describe any ladder between decks.[3]

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.
