Árbol de Piedra ("stone tree") is an isolated rock formation in the Eduardo Avaroa Andean Fauna National Reserve of Sur Lípez Province, Bolivia.[1] Much photographed, it projects out of the altiplano sand dunes of Siloli in the Potosí Department, about 18 kilometres (11 mi) north of Laguna Colorada. Known as the "Stone Tree," it is shaped like a stunted tree about 7 m high. Its shape, particularly the thin stem, are due to strong winds carrying sand and eroding the soft sandstone.[2][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.
