Sphagnum may have a number of different "Sphagnum" species. Individual peat moss plants consist of a main stem, with tightly arranged clusters of branch fascicles usually consisting of two or three spreading branches and two to four hanging branches. The top of the plant, or capitulum, has compact clusters of young branches. Along the stem are scattered leaves of various shapes, named stem leaves; the shape varies according to species. The leaves consist of two kinds of cells; small, green, living cells (chlorophyllose cells), and large, clear, structural, dead cells (hyaline cells). The latter have the large water-holding capacity. "Sphagnum", like
Fuel model their ability to support Wild-land fire and the degree to which such a fire would consume the fuel lying within the bed. Regionally developed by teams of experts, these models were “compiled from scientific literature, fuels photo series, fuels data sets, and expert opinion.” In addition to the standard dead and live components, the FCCS scheme reports assigned and calculated fuel characteristics for each existing fuel bed stratum including the canopy, shrubs, non-woody, woody, litter-lichen-moss, and duff,” allowing a more comprehensive analysis of material within a fuel bed. Furthermore, “the system classifies each fuel bed by calculating fire potentials that
