Sphagnum palustre Sphagnum palustre Sphagnum palustre (Syn. "Sphagnum cymbifolium"), the prairie sphagnum or blunt-leaved bogmoss, is a species of peat moss from the genus "Sphagnum", in the family Sphagnaceae. Like other mosses of this type it can soak up water up to the 30-fold amount of its own dry weight thanks to its elastic spiral fibers. "S. palustre" is rather frequent and is spread almost all over the world. It mainly grows in wet forests and—compared to other specimens of this genus—rarely grows in moors. "Sphagnum palustre" forms firm plants up to 25 centimeter height. The plants are often light green to
Moss Antarctica and Russia, and a case is put forwards for Carboniferous mosses. It has further been claimed that tube-like fossils from the Silurian are the macerated remains of moss calyptræ. Mosses also appear to evolve 2–3 times slower than ferns, gymnosperms and angiosperms. Recent research show that ancient moss could explain why the Ordovician ice ages occurred. When the ancestors of today's moss started to spread on land 470 million years ago, they absorbed CO from the atmosphere and extracted minerals by secreting organic acids that dissolved the rocks they were growing on. These chemically altered rocks in turn reacted
