Vittarioideae worthy of subgeneric rank, while "Rheopteris" had not yet been discovered. "Haplopteris" he explicitly synonymized with "Vittaria" in 1914. Carl Christensen used the name "Vittarioideae" in Verdoorn's "Manual of Pteridology" in 1938, but did not include a description, leaving it nomenclaturally invalid. Ren-Chang Ching raised Vittariaceae to the rank of a family in 1940. The first well-sampled molecular phylogenetic study of the vittarioids was based on the chloroplast gene rbcL. In this study, it was found that the type species of "Monogramma" is embedded in "Haplopteris"; the segregation of "Vaginularia" from "Monogramma" was also supported, as members of "Vaginularia" formed
The Secret Life of Plants Italy during the Second World War The book includes summaries of the life and work of 20th century scientists Jagadish Chandra Bose and Corentin Louis Kervran as well as 19th century scientist George Washington Carver. The book includes experiments on plant stimuli using a polygraph, a method which was pioneered by Cleve Backster. Parts of the book attempt to disparage science, particularly plant biology, for example by claiming science is not concerned with "what makes plants live", in order to promote its own viewpoint that plants have emotions. The authors further say the authorities are unable to accept that emotional
