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
On the cultivation of the plants belonging to the natural order of Proteeae conserved. However it was not possible to conserve species names until the 1980s, by which time the priority of Salisbury's species names had long been accepted. Thus "On the cultivation of the plants belonging to the natural order of Proteeae" is the source of numerous names of Proteaceae taxa. On the cultivation of the plants belonging to the natural order of Proteeae On the cultivation of the plants belonging to the natural order of Proteeae is an 1809 paper on the family Proteaceae of flowering plants. Although nominally written by Joseph Knight as a paper on cultivation techniques, all but
