The lycophytes, when broadly circumscribed, are a group of vascular plants that include the clubmosses.
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 . They have dichotomously branching stems bearing simple leaves called microphylls and reproduce by means of spores borne in sporangia on the sides of the ...
This category is for the "lycophytes". Their formal classification varies as of July 2019 [update] ; this category is for the broadest circumscription including the extinct zosterophylls (e.g. subdivision Lycophytina of Kenrick & Crane (1997)).
In plant anatomy and evolution a microphyll (or lycophyll) is a type of plant leaf with one single, unbranched leaf vein. [1] Plants with microphyll leaves occur early in the fossil record, and few such plants exist today.
Using the narrow circumscription of Lycopodium, in which it is one of nine genera in the subfamily Lycopodioideae, the Checklist of Ferns and Lycophytes of the World recognized the following species as of June 2024: [1] Lycopodium clavatum L. – stag's-horn clubmoss; subcosmopolitan; Lycopodium diaphanum (P.Beauv.) Sw. – Tristan da Cunha
Lycopodiaceae (homosporous lycophytes) split off from the branch leading to Selaginella and Isoetes (heterosporous lycophytes) about ~400 million years ago, during the early Devonian. The two subfamilies Lycopodioideae and Huperzioideae diverged ~350 million years ago, but has evolved so slowly that about 30% of their genes are still in ...

[1] [2] Lycophytes were some of the dominating plant species of the Carboniferous period, and included tree-like species, although extant lycophytes are relatively small plants. [ 3 ] 23,420 species of vascular plant have been recorded in South Africa, making it the sixth most species-rich country in the world and the most species-rich country ...
