Sphagnum imbricatum is a species of moss in the family Sphagnaceae, native to cool temperate parts of Europe and eastern North America, and found sporadically elsewhere. [1] In the past it was used as a substitute for cotton in surgical dressings.
The word whirligig derives from two Middle English words: whirlen (to whirl) and gigg (top), [9] or literally "to whirl a top". The Oxford English Dictionary cites the Promptorium parvulorum (c. 1440), the first English-Latin dictionary, which contains the definition "Whyrlegyge, chyldys game, Latin: giracu-lum". [ 10 ]
Sphagnum is a genus of approximately 380 accepted species [2] [3] of mosses, commonly known as sphagnum moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of Sphagnum can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 ...
It carries the wallower, Great Spur Wheel and sometimes a Crown Wheel. Wallower The Wallower is a small gear at the base of the upright shaft in a watermill, it is driven by the Pit Wheel. Waterwheel A waterwheel is a source of power for a watermill. It is mounted on the axle and drives the mill by a Pit Wheel or Rim Drive.
Wheels can also lose traction when surface conditions reduce available traction such as on snow and ice. As an open differential delivers only enough torque to cause the "weakest" wheel to spin, if one drive wheel is stationary on a low traction surface (mud, ice, etc.), the deliverable torque is limited to the traction available on it.
Sphagnum leucobryoides T. Yamag., Seppelt & Z. Iwats. (now placed in genus Ambuchanania in family Ambuchananiaceae ) Sphagnum sericeum Müll. Hal. (transferred to genus Flatbergium in family Flatbergiaceae)
Sphagnum cuspidatum is a dominant species in the bogs that it inhabits. [6] In wetlands, they consume methane through symbiosis with partly endophytic methanotrophic bacteria, leading to highly effective in situ methane recycling preventing large-scale methane emission into the atmosphere.
Sphagnum wulfianum, commonly known as Wulf's peatmoss, is a species of moss belonging to the family Sphagnaceae. It has a circumboreal distribution, occurring primarily in moist boreal forest environments across Eurasia and North America, with rare occurrences in Arctic tundra regions.
