The Japanese government-issued dollar was a form of currency issued between 1942 and 1945 for use within the territories of Singapore, Malaya, North Borneo, Sarawak and Brunei, under occupation by Imperial Japan during World War II. The currency, informally referred to as "banana money", was released solely in the form of banknotes, as metals were considered essential to the war effort. The languages used on the notes were reduced to English and Japanese. Each note bears a different obverse and reverse design, but all have a similar layout, and were marked with stamped block letters that begin with "M" for "Malaya". This 1942 one-dollar Japanese-issued banknote, depicting breadfruit and coconut trees on the obverse, is part of the National Numismatic Collection at the Smithsonian Institution.

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.
