A germanide is any binary compound of germanium and a more electropositive element. The composition of most germanides is analogous to that of the corresponding silicides and does not follow formal valence rules. The germanides of alkali and alkaline earth metals, are readily decomposed by water and acids to give germanium hydrides; most germanides of the transition metals resist the action of acids and alkalies. The main method of producing germanides is the melting or sintering of the components.[1][2]
The IUPAC Red Book uses the name tetragermide for compounds containing Ge4− and instead uses the term germanide (or trihydridogermanate(1-)) for the GeH−3 anion.[3]

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.
