Drepanocladus is a genus of deciduous mosses and mostly includes strongly developed marsh and aquatic mosses that can occur in both land and water forms. The individual species can vary greatly in terms of vegetation and are often branched.
The 30 species of the genus are found in the temperate and cool areas of both the northern and southern hemisphere and in the mountains of the tropics and subtropics . There are 13 species in Europe.
features
The leaves always have a long vein, which in some species can also be double. Only D. fluitans develops a short vein. The leaves are also straight to circularly curved, always without folds and pointed like a sickle, whereby deviations can occur more frequently in the water forms. The leaves are straight to circularly curved and have a dense prosenchymatic leaf cell network, whereby the leaf wing cells are well developed, but may not be present in some species. Drepanocladus has a double peristome (the tooth-like coating of the leaf moss capsule) and a slightly inclined capsule.
