Esprit Jouffret (15 March 1837 – 6 November 1904) was a French artillery officer,[1] insurance actuary and mathematician, author of Traité élémentaire de géométrie à quatre dimensions (Elementary Treatise on the Geometry of Four Dimensions, 1903),[2] a popularization of Henri Poincaré's Science and Hypothesis in which Jouffret described hypercubes and other complex polyhedra in four dimensions and projected them onto the two-dimensional page.
Maurice Princet brought Traite to artist Pablo Picasso's attention. Picasso's sketchbooks for his 1907 painting Les Demoiselles d'Avignon illustrate Jouffret's influence on the artist's work.<ref>Miller. Einstein, Picasso. pp. 106–117.

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.
