A. Non-Flowering Plants
More extensive information on flowering plants can be found in a separate blog post.
B. Mosses (Pottiaceae)
This is the most numerous moss family on the planet, with nearly 1500 species.
C. Bird's-claw Beard Moss (Barbula unguiculata)
This species forms clusters or mats of yellow-green turfs with erect unbranched stems, especially in disturbed, open habitats. In the cemetery it is on a gravel grave.
There are 763 species of British mosses, which are small, non-vascular plants forming dense green clumps or mats in damp or shady places. Perennial mosses are evergreen. Individual plants usually have simple leaves attached to a stem that may be branched or unbranched. Instead of roots mosses have rhizoids. Mosses assist control of soil erosion by providing surface cover and by absorbing water. An important genus is Sphagnum, whose species form peat. Vast mires of moss lock up huge quantities of carbon, of vital importance in the mitigation of climate change.
Mosses reproduce by the release of spores from little capsules on short stalks. Most mosses have one of two growth forms. Acrocarp mosses grow upright, forming mats, with capsules on the tips of their shoots. Pleurocarp mosses have sprawling growth, with capsules on the sides of their shoots.
