Lycopodiopsida - Wikipedia
Lycopodiopsida is a class of vascular plants also known as lycopsids, [1] lycopods, or lycophytes. Members of the class are also called clubmosses, firmosses, spikemosses and quillworts.
Lycophyte - Wikipedia
The lycophytes, when broadly circumscribed, are a group of vascular plants that include the clubmosses. They are sometimes placed in a division Lycopodiophyta or Lycophyta or in a subdivision Lycopodiophytina.

Plant reproductive system - Lycopsids, Pollination, Fertilization: In the genus Lycopodium, the club mosses, the sporangia are closely associated with the leaves. In some species (L. lucidulum), the sporangium-bearing leaves (sporophylls) occur in zones among the vegetative portions of the stems.
Lycopsida - Encyclopedia.com
2018年5月8日 · Lycopsida (lycopods) Class of the Pterido-phytina, represented today by relatively small plants, the club mosses, although in the Carboniferous they included large trees which dominated the coal-swamp vegetation of the time. The oldest lycopods date from the Devonian and derived from the most primitive of vascular plants, the psilophytes.
Lycopsid | plant | Britannica
Lycophytes were the first plants with well-differentiated shoot systems, and they are the most ancient groups of vascular plants with living… …vascular plants include the seedless lycophytes and ferns (both groups are considered lower vascular plants) and the two groups of seed plants, the gymnosperms and angiosperms.
Spore Evidence for the Origin of Isoetalean Lycopsids? - PMC
A new hypothesis about the origin of isoetalean lycopsids was proposed based on palynological data. The occurrence of three apical papillae on the proximal surfaces of miospores is a significant palynological feature that is clearly defined in …
Lycophytes - an overview | ScienceDirect Topics
The Lycopodiophyta, or lycophytes (also commonly called lycopods), are a lineage of plants that diverged after the rhyniophytes. An extinct, probably paraphyletic, fossil group, known as the zosterophyllophytes [Zosterophyllophytina], diverged along the immediate lineage leading to lycophytes (Figure 4.1).

Lycopsids, are a group of very ancient vascular plants that are only distantly related to other land plants. They have a long history stretching back possibly to the late Silurian period. Their living representatives include club mosses and quillworts, but in past ages they dominate the landscape with huge forests.
The rhizomorphic lycopsids are a putatively monophyletic group delimited by the rhizomor-phic syndrome: centralized determinate growth and secondary thickening in their rooting systems.
Lycopodiaceae - an overview | ScienceDirect Topics
Lycopsids (Lycopsida) have a basal position among the vascular plants. Extant lycopods are all herbaceous plants. They are characterized by having upright dichotomously branching stems growing from horizontal rhizomes and bearing densely spaced leaves.
