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 ...
Lycopodium (from Ancient Greek lykos, wolf and podion, diminutive of pous, foot) [2] is a genus of clubmosses, also known as ground pines or creeping cedars, [3] in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use.
Within the family Lycopodiaceae, there is support for three subgroups. In 2016, Field et al. proposed that the primary division is between Lycopodielloideae plus Lycopodioideae (which comprised their Lycopodioideae) and Huperzioideae (subfamilies sensu PPG I). [7]
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.
Diphasiastrum digitatum is known as groundcedar, running cedar or crowsfoot, along with other members of its genus, but the common name fan clubmoss can be used to refer to it specifically.
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.
Lycopodium clavatum is a spore-bearing vascular plant, growing mainly prostrate along the ground with stems up to 1 m (39 in) long; the stems are much branched, and densely clothed with small, spirally arranged microphyll leaves.
Diphasiastrum is a genus of clubmosses in the plant family Lycopodiaceae. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the subfamily Lycopodioideae. [1] It is closely related to the genus Lycopodium, and some botanists treat it within a broad view of that genus as a section, Lycopodium sect. Complanata.
