Cryptogramma is a genus of ferns known commonly as parsley ferns or rockbrakes. They are one of the three genera in the subfamily Cryptogrammoideae of the family Pteridaceae.[1] Cryptogramma ferns can be found in temperate regions on several continents worldwide. These ferns have two kinds of leaves which often look so different that at first glance they appear to belong to different plants. The fertile leaves have long, narrow, bumpy segments with undersides covered thickly in sporangia. The edges of the segments may curl back to cover the sporangia, forming a false indusium. The sterile leaves have thinner, wider segments which may be rounded and resemble the leaves of parsley. These ferns grow in rocky areas, often in crevices and cracks, particularly on mountain scree.
Distribution
[edit]Species in this genus are distributed widely over the temperate Northern Hemisphere, with one species in the temperate Southern Hemisphere in Chile and Argentina.[2]
Taxonomy

Eight species are accepted by the Plants of the World Online (POWO) database:[2]
- Cryptogramma acrostichoides R.Br.
- Cryptogramma brunoniana Wall. ex Hook. & Grev.
- Cryptogramma cascadensis E.R.Alverson
- Cryptogramma crispa (L.) R.Br.
- Cryptogramma fumariifolia (Phil.) Christ
- Cryptogramma gorovoii Vaganov & Shmakov
- Cryptogramma sitchensis (Rupr.) T.Moore
- Cryptogramma stelleri (S.G.Gmel.) Prantl
Two other species, Cryptogramma bithynica S.Jess., L.Lehm. & Bujnoch and Cryptogramma raddeana Fomin, are accepted by some authors,[3][a] but are treated as a synonym of C. crispa, and a subspecies of C. brunoniana, respectively, by POWO.[2]
