Lotaustralin is a cyanogenic glucoside found in small amounts in Fabaceae austral trefoil (Lotus australis),[1] cassava (Manihot esculenta), lima bean (Phaseolus lunatus),[2] roseroot (Rhodiola rosea)[3] and white clover (Trifolium repens),[4] among other plants. Lotaustralin is the glucoside of methyl ethyl ketone cyanohydrin and is structurally related to linamarin, the acetone cyanohydrin glucoside also found in these plants. Both lotaustralin and linamarin may be hydrolyzed by the enzyme linamarase to form glucose and a precursor to the toxic compound hydrogen cyanide.

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.
