Marsh clubmoss  (Lycopodiella inundata)

The ancestry of clubmosses can be traced back to at least the Carboniferous period, 300 million years ago. Most of the land on the planet was then composed of one huge super-continent called Pangea. A large part formed an extensive area of wetland, populated by the giant clubmosses. These tree-like plants grew to over 35 metres tall extremely quickly, at a rate of several metres a year. It is believed that they only reproduced once, at their maximum height and size, before dying and sinking back into the wet ground. Conditions at the time favoured the formation of vast peatlands and, over the vast periods of geological time, these peats were compressed and formed the extensive coalfields now found over much of the Earth's surface.

The spores of clubmoss are highly inflammable, and have been put to a number of different uses over the centuries. Known as 'Lycopodium powder', they have been used as a dusting powder for infants' sores, in treatment for irritation and spasm of the bladder, and used in pyrotechny in the making of fireworks, and for artificial lightning on the stage. Another use has been dyeing woollen cloth, and as the lubricant on condoms.
