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
Flowering Plants of Africa Flowering Plants of Africa Flowering Plants of Africa is a series of illustrated botanical magazines akin to "Curtis's Botanical Magazine", initiated as Flowering Plants of South Africa by I. B. Pole-Evans in 1920. It is now published by the South African National Biodiversity Institute (SANBI) in Pretoria. The magazine depicts and describes flowering plants from Africa and its neighbouring islands. The first volumes were printed in England by L. Reeve & Co. These first illustrations were done in black and white by lithography, zinc plates later replacing the stone. A copy of the original water colour guided teams of hand-colour
