Acrosorus is a genus of grammitid ferns in the family Polypodiaceae, known from the Philippines, Malesia, Thailand, and the Pacific islands.
Description
Members of the genus bear a single sorus on each pinna of the divided leaf blade. The edges of the pinnae are rolled back towards their tips and cover the sori.[1]
Taxonomy
The genus was created by Edwin Copeland in 1906, to accommodate a group of ferns similar to Prosaptia and until then classified in Davallia.[1]
Currently recognized species in the genus are:
- Acrosorus friderici-et-pauli (Christ) Copel. (includes Acrosorus exaltatus (Copel.) Copel.)
- Acrosorus grammitidiphyllus (Copel.) Parris
- Acrosorus merrillii Copel.
- Acrosorus reineckei (Christ) Copel.
- Acrosorus schlechteri (Christ) Christ
- Acrosorus sclerophyllus (Alderw.) Parris
- Acrosorus streptophyllus (Baker) Copel.
- Acrosorus subtriangularis (Alderw.) Parris
- Acrosorus symmetricus Copel.
- Acrosorus triangularis Copel.
