Aspleniaceae are a family of perennial herbaceous ferns. At present it is considered that the family consists of a genus (Asplenium) and some 28 species. The members of the family are distributed throughout the world.
The stems are erect or semi-erect, rarely long, creeping, scaly, radially symmetric. The leaves are monomorphic (of the same shape), rarely dimorphic, with fertile leaves being higher and more erect than the sterile ones. Most members developed sporangia with a membranous knot.
The species of the Aspleniumgenus are extremely popular not only due to morphological features, but also because of their outstanding capability to form different hybrids with fantastic shapes of the leaves.
