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
A proposed phylogeny of the vascular plants after Kenrick and Crane 1997 [16] is as follows, with modification to the gymnosperms from Christenhusz et al. (2011a), [17] Pteridophyta from Smith et al. [18] and lycophytes and ferns by Christenhusz et al. (2011b) [19] The cladogram distinguishes the rhyniophytes from the "true" tracheophytes, the ...
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 ...
Increasingly, however, researchers are wondering if there is a whole-body memory, that is, if different parts of our bodies can also make and store a type of memory, and if so, how these other ...
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.
