This is the Japanese Type 93, a high-explosive (HE), circular, pressure-actuated, anti-vehicle (AV) blast landmine used during the Second World War. The Type 93 landmine can be found made of copper, brass or steel and is fitted with the T93 landmine fuze. The T93 fuze had a variable activation pressure, achieved through the use of different thickness shear wires. The main charge could be supplemented with additional explosives buried under the landmine.

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.
