Evolutionary history of plants foliage consisted of fern-like fronds, although they were not closely related to ferns. The oldest fossil evidence of seed plants is of Late Devonian age, and they appear to have evolved out of an earlier group known as the progymnosperms. These early seed plants ranged from trees to small, rambling shrubs; like most early progymnosperms, they were woody plants with fern-like foliage. They all bore ovules, but no cones, fruit or similar. While it is difficult to track the early evolution of seeds, the lineage of the seed ferns may be traced from the simple trimerophytes through homosporous Aneurophytes. This
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.
