Under the Whyte notation for the classification of steam locomotives, 2-2-4-0T represents the wheel arrangement of two leading wheels on one axle, two driving wheels powered from the inside cylinders, four coupled driving wheels powered from the outside cylinders but no trailing wheels.
Usage
[edit]This unusual wheel arrangement appears only ever to have been used on one divided drive compound tank locomotive designed by Francis Webb of the London and North Western Railway, No. 777. The locomotive was nicknamed “Cold Dinners” which suggests that it was not successful. It was withdrawn in 1901.[1]

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.
