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
Carnivorous plant more or less than this optimum will take up less carbon dioxide than an optimal plant, and hence growing less well. These plants will be at a selective disadvantage. At zero investment the growth is zero, because a non-carnivorous plant cannot survive in a habitat with absolutely no soil-borne nutrients. Such habitats do not exist, so for example, "Sphagnum" absorbs the tiny amounts of nitrates and phosphates in rain very efficiently and also forms symbioses with diazotrophic cyanobacteria. In a habitat with abundant soil nutrients but little light (as shown above), the gross photosynthesis curve will be lower and flatter,
