Timmia is a genus of the moss and forms its own subclass Timmiidae . The genus is named after the German botanist Joachim Christian Timm (1734–1805).
features
The habitus of the species resembles the genus Polytrichum , so they are quite large (two to nine centimeters high), acrocarpic mosses. The leaflets are lanceolate to linear and are arranged in a spiral. They consist of linear, smooth or papillary cells at the base and small, square to hexagonal cells at the top. The leaf margin is sawn. The leaf vein ends in front of the leaf tip, but extends beyond half of the leaf.
The capsule stands on a long seta and is egg-shaped and nodding or hanging. The kalyptra is symmetrical. The peristome is double with 16 teeth.
Occurrence
The family occurs in the northern hemisphere, but is also found in Hawaii and New Zealand. They are mosses that grow on the ground or on rocks. They are rare in Europe.
Systematics
The genus is placed in its own subclass and consists of six species. Five species occur in Europe that are native to Germany:
