Lycopodiaceae Clubmoss Family

Lycopodiaceae 10-15 genera 350-400 species Consists of a rhizome with adventitious roots Small, creeping, terrestrial, vascular plants, which lack flowers and reproduce sexually by spores. The sporophyte consists of true roots, an aerial stem and scale-like leaves

Lycopodium annotinum Bristly clubmoss Horizontal stems grow up to 40”, branching, creeping on ground, with upright groups of branching stems Vertical stem stiff, erect; circular or oval in cross-section; bristly with few branches - Leaves 1/3" long, pointing downward Cones individual, slim and pointed, yellow, 1 ½ “

Lycopodium clavatum Running Clubmoss It is a spore-bearing vascular plant, growing mainly along the ground with stems up to 1 m long Stems have many branches, and have small spirally-arranged leaves -The horizontal stems produce roots allowing the stem to grow indefinitely along the ground Leaves are 3-5 mm long. The branches bearing spore cones turn erect, reaching 5-15 cm above ground Cones are yellow-green, 2-3 cm long and 5 mm broad

Lycopodium spp. Club mosses Have horizontal branching stems, both underground and above These plants produce spores in a cone like structure at the end of the stem. Once the spores germinate, they develop into a thallus which then produce male and female egg cells. This can take up to twenty years to complete.

Huperzia lucidula Shining firmoss They grow 14-20 cm long, sometimes up to 1 m long Leaves are 7-11 mm long, narrow, shiny, and evergreen. The edges are irregularly toothed. The sporangia (spore cases) are in the upper leaves Roots of this plant grow from a creeping, branching, underground rhizome Bright, vivid green color

Lycopodium dendroideum/hickeyi Groundpines Spreads by subterranean horizontal stems, each upright shoot appearing somewhat like a small individual tree. The lateral branches are round, not flattened.

Diphasiastrum complanatum/digitatum Northern & Wirey groundcedar A creeping, evergreen, rhizomatous clubmoss; has the appearance of a miniature tree Vertical stem branchlets regularly fan-shaped, generally on a horizontal plane, flat in cross section, blade-like, their undersides dull, pale, flat; their uppersides green, flat, shiny. Horizontal stems are on or just below the surface Cones 2-4 per upright shoot, ½"-1½" long; has elongated sterile tip which occurs on about half the specimens. Cone stalks are 1¾"-5" long.
