A testbed aircraft is an aeroplane, helicopter or other kind of aircraft intended for flight research or testing the aircraft concepts or on-board equipment. These could be specially designed or modified from serial production aircraft.[1][2]

For example, in development of new aircraft engines, these are fitted to a testbed aircraft for flight testing, before certification. New instruments wiring and equipment, a fuel system and piping, structural alterations to the wings, and other adjustments are needed for this adaptation.[3][4]
The Folland Fo.108 (nicknamed the "Folland Frightful") was a dedicated engine testbed aircraft in service from 1940. The aircraft had a mid-fuselage cabin for test instrumentation and observers. Twelve were built and provided to British aero-engine companies. A large number of aircraft-testbeds have been produced and tested since 1941 in the USSR and Russia by the Gromov Flight Research Institute.[2][5]
AlliedSignal,[6] Honeywell Aerospace,[7] Pratt & Whitney,[8] and other aerospace companies used Boeing jetliners as flying testbed aircraft.[9]

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.
