  Lycopodiaceae - Wikipedia, the free encyclopedia
The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) is a family of primitive vascular plants, including all of the core clubmosses.
These plants bear spores on specialized structures at the apex of a shoot; they resemble a tiny battle club, from which the common name derives.

 Lab V - Lycophytes (1)
The heterosporous lycopsids, Isoetes and Selaginella, appear to be monophyletic, as is Lycopodiaceae.
Many groups (Lycopodiaceae is an exception) have a ligule or small flap of tissue adaxially above each microphyll, or its homologous sporophyll.
Sporangia are commonly stalked, kidney-shaped, and are borne adaxially on modified leaves (sporophylls) either clustered in strobili or on fertile portions of the axis (VG 1:5).

 Lycopodiaceae in Flora of North America @ efloras.org
The Lycopodiaceae are an extremely diverse, ancient family.
The family may contain even more than the estimated 400 species because the tropical members and the very large genus Phlegmariurus are still poorly known.
The relationships among genera of Lycopodiaceae are not well understood because large evolutionary gaps exist among most genera.

 Lycopodiopsida - Wikipedia, the free encyclopedia
The Class Lycopodiopsida as interpreted here contains a single living order, the Lycopodiales, and a single extinct order, the Drepanophycales.
There are two major groups of large clubmosses: the Lycopodiaceae and the Huperziaceae.
The Family Lycopodiaceae comprises the extant genus, Lycopodium, which includes the Wolf's-foot clubmoss, Lycopodium clavatum, Ground-pine, Lycopodium obscurum, Southern ground-cedar, Lycopodium digitatum, and other species.

 Flora of the Canadian Arctic Archipelago - Lycopodiaceae
On the other hand, members of the Lycopodiaceae and Equisetaceae have the capacity to produce completely homozygous offspring since a gametophyte and its gametes are produced from a single haploid spore.
Wagner and Beitel (1992), provided a generic classification of modern North American Lycopodiaceae based on 50 characters of anatomy, chromosomes, spores and gametophytes and analysed the data gathered using his ground-plan-divergence method of cladistics (Wagner 1980).
Wagner and Beitel (1992) were aware of the work of Josef Holub and Benjamin Ǿllgaard and recognized that both had made extensive contributions to the knowledge and understanding of the family including providing two systems of classification (Holub, 1983 and Ǿllgaard, 1987).

 Plant Systematics: Lycopodiaceae
The Lycopodiaceae have a worldwide distribution, but are not present in arid habitats.
The family Lycopodiaceae consists of 10-15 genera and 350-400 species.
Some of the most well known genera are Diphasiastrum, Huperzia, and Lycopodiella, the largest genus is Phlegmariurus of about 300 species.

Hitchcock and Cronquist recognize the Division Lycopodiophyta with two classes: Class Lycopodiopsida (the plants homosporous) and Class Isoetopsida (the plants heterosporous with small microspores and larger megaspores).
The club mosses were one of the largest components of the forests on the earth during the Carboniferous period approximately 300 million years ago.
There are two genera in the Lycopodiaceae or Club Moss family, which are Lycopodium, and Phyoglossum.

Pteridophytes of the Canadian Arctic Archipelago - Lycopodiaceae
Wagner and Beitel (1992), in a paper on the generic classification of modern North American Lycopodiaceae, justify segregating taxa formally treated as all being in the genus Lycopodium.
These authors used characters of anatomy, chromosomes, spores, and gametophytes finding that the groups they recognized as separate genera have many distinguishing features providing strong gaps that separate them from each other.

 Huperzia   (Site not responding. Last check: 2007-11-05)
Huperzia is a type of moss that grows in China.
It is related to club mosses (the Lycopodiaceae family) and is known to some botanists as Lycopodium serratum.
Modern herbal preparations use only the isolated alkaloid known as huperzine A. Huperzia has been used in connection with the following conditions (refer to the individual health concern for complete information):
