Genera

Sciadopityaceae, commonly called umbrella pines, is a family of conifers now endemic to Japan but in prehistoric times they could also be found in Europe and China. The sole living member of the family is Sciadopitys verticillata, while several several extinct genera are known from the fossil record. Wood suggested to belong to the family has been reported from the Jurassic of China,[1][2] though the relationship of pre-Cretaceous fossils to Sciadopitys is ambiguous. Sciadopitys species are known from the Late Cretaceous of Japan before becoming widespread across Laurasia during most of the Cenozoic, especially in Europe until the Pliocene.[3]

  1. 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.
