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
Directorate of Medicinal and Aromatic Plants Research and it coordinates and monitors research work of 23 centres spread across the country working on various other medicinal and aromatic plants. To its credit, it has released 26 varieties of medicinal plants and seven varieties of aromatic plants. The DMAPR is also maintaining 830 germplasm of medicinal and aromatic plants at their Field Gene Bank. The DMAPR houses Medicinal and Aromatic Plants Association of India which publishes the "Open Access Journal of Medicinal and Aromatic Plants", a scholarly research open access journal related to medicinal and aromatic plants.
