The Nikon D40 is a 6.1-megapixel DX format DSLR Nikon F-mount camera announced by Nikon on November 16, 2006. It replaces the D50 as Nikon's entry level DSLR. It features a 2.5-inch 230,000-dot resolution LCD monitor, CCD sensor with ISO 200-1600 (3200 Hi-1) and 3D Color Matrix Metering.
The D40 was the first Nikon DSLR without an in-body focus motor. Autofocus requires the use of a lens with an integrated autofocus-motor.[4]
In March 2007, Nikon released a sister model, the D40x, which included a 10.2-megapixel sensor and several other changes over the original D40.[5]

Nikon D40x
[edit]On March 6, 2007, Nikon introduced the D40X, a sister camera to the D40.[5] While identical in external design to the D40, it has a 10.2-megapixel CCD sensor, continuous shooting up to 3 frames per second, and a base sensitivity of ISO 100. It has a flash sync speed of 1/200 of a second.
A new consumer-level telephoto zoom with vibration reduction debuted alongside the launch. Nikon ceased production of the D40X in December 2007, shortly before they introduced its successor, the Nikon D60.

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.
