	Lycophyta
		Plants in the Lycophyta have erect stems as well as Stolons and Rhizomes.
		They are relatively large compared to Hepatophyta, Bryophyta and Psilophyta but they rarely exceed a meter in height.
		The next major step in evolution was the development of a complex leaf called a

	Division Lycophyta
		During the Carboniferous Period of geological time this group was represented by some of the largest and most numerous plants.
		The Division Lycophyta is composed of the following:

	Lycophyta
		The Lycophyta is a tracheophyte division of the kingdom Plantae that includes the most "primitive" of the vascular plants.
		All member species reproduce by shedding spore and macroscopic alternation of generations, but some are homosporous and some are heterosporous.
		There are three main groups in the Lycophyta, sometimes divided at the order level and sometimes at the class level.

		The Division Lycophyta is a tracheophyte subdivision of the Kingdom Plantae that includes some of the most "primitive" of extant (living) vascular plants.
		These species reproduce by shedding spores and have macroscopic alternation of generations, although some are homosporous while others are heterosporous.
		There are three main groups within the Lycophyta, sometimes separated at the level of order and sometimes at the level of class.

	Re: What role do mosses have in the environment and with humans?
		Club moss is the common name for the phylum Lycophyta, the family Lycopodiaceae and the genus Lycopodium.
		Lycophyta are not bryophytes but seedless vascular plants, a group that also includes ferns, whisk ferns, and horsetails.
		Lycophyta are mainly small evergreen plants that often help prevent soil erosion and assist in soil formation.

		Right, clubmosses belong in the Lycophyta, a small group of survivors from the age of coal.
		Right, horsetails are also survivors of the division Sphenophyta that was dominant in the Carboniferous era and you probably realise by now that ferns belong in the Pterophyta.
		No the Lycophyta include the clubmosses but not the horsetails.

		The Lycophyta is a group of spore-bearing, vascular plants with a long evolutionary history reaching well back into the Paleozoic Era.
		However, the living members of this group are limited to 5 genera, only one of which (Lycopodium) has thus far been identified in southwest Virginia.
		NOTE: The four genera below are believed to be different structures from the same plant.

	Botany Glossary "L"
		Lycopodium is a genus in the group of plants known commonly as the club mosses.
		These are tracheophytes that are in the division Lycophyta characterized by containing short side branches off the main rhizome.
		At the tip of the branches are a cluster of sporophylls that produce spores.

		Sphagnum moss is haploid, bears archegonia at the ends of branches, has a dependent sporophyte with a capsule which has an annulus, operculum, columella and spores, but lacks a peristome, has "leaves" which are one cell thick and are all the same shape.

		The clubmosses, Phylum Lycophyta, are relatively common, but often overlooked in the forest ecosystems in which they thrive.
		Two-hundred-million years ago, however, the forest itself consisted of tall clubmosses that would have been hard to overlook!
