Nederlandse naam:		Grote wolfsklauw
English name:		wolf's-foot clubmoss, stag's-horn clubmoss, Running Ground Pine,
Plant Family:		Lycopodiaceae, clubmosses, Lummerväxter

Life form:		spore-bearing vascular plant
Stems:		Up to 1 m long; much branched, densely clothed with small spirally-arranged leaves; branches bearing spore cones turn erect, reaching 5-15 cm above ground, and have fewer leaves than the horizontal branches; horizontal stems produce roots at frequent intervals along their length, allowing the stem to grow indefinitely along the ground.

Derivation of the botanical name: Lycopodiumfrom the Greek word lycos, "wolf" and podion, diminutive of pous, foot", in reference to the resemblance of the branch tips to a wolf's paw. clavatum, Latin, "club shaped" The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy. Distinguished from tree like clubmosses by its running habit. Distinguished from other running clubmosses by its branching, multiple cones on extremely long stems, and horizontal stem on surface of ground.
