Lithophragma is a genus of flowering plants in the saxifrage family containing about nine species native to western North America. These plants are known generally as woodland stars. The petals of the flowers are usually bright white with deep, long lobes or teeth. Each petal may look like three to five petals, when at closer inspection the lobes fuse into a single petal at its base. Most species reproduce via bulblets instead of seeds. L. maximum is a federally listed endangered species. Lithophragma specifically coevolved with moths of the genus Greya, who pollinate and only lay eggs on Lithophragma plants.[2]
Species
[edit]There are 10 species.[1] Plants of the World Online and the Flora of North America North of Mexico elevate Lithophragma trifoliatum to species status,[3][1] but the Jepson Manual considers it to be a variety of L. parviflorum (L. parviflorum var. trifoliatum) restricted to California.[4]

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.
