French aircraft manufacturer Dassault used the name Étendard ("Standard", in the sense of a flag or banner) for a family of related aircraft projects beginning in the late 1950s. Versions that at least reached prototype stage were:
- Dassault Étendard II, a prototype for the French Air Force
- Dassault Étendard IV, a strike fighter produced for the French Navy
- Dassault Étendard VI, an unsuccessful competitor in the NBMR-1 NATO fighter competition
- Dassault Super Étendard, a derivative of the Étendard IV that served with Argentine Naval Aviation, French Naval Aviation and the Iraqi Air Force.
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.
