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 ...
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
Pteridophytes (ferns and lycophytes) are free-sporing vascular plants that have a life cycle with alternating, free-living gametophyte and sporophyte phases that are independent at maturity. The body of the sporophyte is well differentiated into roots, stem and leaves. The root system is always adventitious. The stem is either underground or ...
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)).
The powder consists of the dry spores of clubmoss plants, or various fern relatives principally in the genera Lycopodium and Diphasiastrum.The preferred source species are Lycopodium clavatum (stag's horn clubmoss) and Diphasiastrum digitatum (common groundcedar), because these widespread and often locally abundant species are both prolific in their spore production and easy to collect.
Dendrolycopodium obscurum, synonym Lycopodium obscurum, commonly called rare clubmoss, [2] ground pine, [3] or princess pine, [4] is a North American species of clubmoss in the family Lycopodiaceae. [5]
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 ...
