Restoration Lepidostrobus, the strobilus of Lepidodendron lycophytes. Lepidodendron species were comparable in size to modern trees. The plants had tapering trunks as wide as 2 m (6.6 ft) at their base that rose to about 40 m (130 ft) [2] and even 50 m (160 ft), [1] arising from an underground system of horizontally spreading branches that were covered with many rootlets.
Lycopodiopsida is a class of vascular plants also known as 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 stems at the bases of the leaves.
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. They are one of the oldest lineages of extant (living) vascular plants; the group contains extinct plants that have been dated from the ...
Sigillaria was a tree-like plant reaching a height up to 30 m (98 ft), [1] and lycopsids were capable to reach a height of up to 50 m (160 ft). [4] These lycopsids had a tall, single or occasionally forked trunk [2] that lacked wood. Support came from a layer of closely packed leaf bases just below the surface of the trunk, while the center was ...
Lycopodium (from 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. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), Lycopodium is one of nine genera ...
The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) are an old family of vascular plants, including all of the core clubmosses and firmosses, comprising 16 accepted genera [2] and about 400 known species. [3] This family originated about 380 million years ago in the early Devonian, though the diversity within the family has been much ...
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
The Devonian (/ d ə ˈ v oʊ n i. ən, d ɛ-/ də-VOH-nee-ən, deh-) [9] [10] is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at 419.2 million years ago (), to the beginning of the succeeding Carboniferous period at 358.9 Ma.
