A study of the morphologies and evolutionary relationships of Upper Carboniferous coal swamp lycopods indicated that plants traditionally treated as Lepidodendron brevifoHum were distinct from Lepidodendron at the generic level, and were not part of a morphological cline between Lepidodendron and Lepidophloios. The description of a new genus and species by Morey and Morey (1977), based on a specimen identical to L. brevifolium distal branches, results in the inclusions of L. brevifolium in… 
Re-interpretation of Wexfordia hookense from the Upper Devonian of Ireland as an arborescent lycophyte
TLDR
Fine structure of tracheids and additional anatomical features strongly support affinities with Carboniferous arborescent Isoetales, rather than Devonian Protolepidodendrales, and further support the hypothesis that radiation in this lineage was well underway prior to the carboniferous.
Growth habit of the late Paleozoic rhizomorphic tree-lycopsid family Diaphorodendraceae: phylogenetic, evolutionary, and paleoecological significance.
TLDR
This discovery identifies the plagiotropic growth habit, dominated by serial lateral branches, as ubiquitous in the Diaphorodendraceae and also as unequivocally primitive within Isoetales s.l., a conclusion supported by both the revised morphological cladistic analysis and relative first appearances of taxa in the fossil record.
A new species of Lepidostrobus from the Upper Devonian of Xinjiang, China and its bearing on the phylogenetic significance of the order Isoëtales
TLDR
It is suggested that the reproductive strategies represented by bisporangiates- and monosporangiate-strobili had proliferated by the Late Devonian, which implies that phylogenetically advanced arborescent lycopsids bearing Lepidostrobus strobiliHad an earlier origin than previously thought.
Systematics, Phylogenetics, and Reproductive Biology of Flemingites arcuatus sp. nov., an Exceptionally Preserved and Partially Reconstructed Carboniferous Arborescent Lycopsid
TLDR
Stratigraphic comparisons of the megafossils and spores restrict the likely age of the cobble from the Early Mississippian to the Middle Pennsylvanian, where the plants were deposited alongside univalve crustaceans in a swamp environment where preservation was probably enhanced by local volcanic activity.
Lycaugea edieae gen. et sp. nov., a Late Devonian Lycopsid from New South Wales, Australia
Premise of research. Resolving the time and patterns of origination of the Isoetales that thrived in the wet habitats of the late Paleozoic and have extant representatives in the genus Isoetes
An anatomically preserved arborescent lycopsid, Sublepidodendron songziense (Sublepidodendraceae), from the Late Devonian of Hubei, China.
TLDR
Widespread occurrence of Sublepidodendron implies that phylogenetically advanced arborescent lycopsids must have diverged by the Late Devonian, and similarities to synapomorphies of Diaphorodendraceae and Lepidodendrales suggest that S. songziense bears a closer affinity to Lepididod Endrales rather than ProtolepidODendrale, as formerly thought.
Yuguangia ordinata gen. et sp. nov., a New Lycopsid from the Middle Devonian (Late Givetian) of Yunnan, China, and Its Phylogenetic Implications
A new heterosporous and ligulate lycopsid, Yuguangia ordinata gen. et sp. nov., is described from the Haikou Formation (late Givetian) of Yunnan Province, southwestern China. Its slender stems branch
Isoetalean Lycopsid Evolution: from the Devonian to the Present
TLDR
It is interesting that several morphological characters of modern Isoetes are present as early as the Triassic: monolete microspores, sunken sporangia and elaborate ligules with glossopodia occur within elongate-stemmed Triassic forms.

PALEOZOIC LYCOPSID FRUCTIFICATIONS. III. CONSPECIFICITY OF BRITISH AND NORTH AMERICAN LEPIDOSTROBUS PETRIFACTIONS
TLDR
It was found that the specimens possessed many characters considered diagnostic for the previously described taxa Lepidostrobus oldhamius, and the task of identifying the species represented by the 30 specimens resolved itself into a reexamination of the type specimens of the aforementioned taxa.
Modes of evolution and their chronostratigraphic significance; evidence from Devonian invertebrates in the Michigan Basin
TLDR
The origin and evolutionary histories of the two most abundant and diverse genera of inver- tebrates in the Detroit River Group and associated rocks in the vicinity of the Michigan Basin appear to support the models of either allopatric speciation and punctuated equilibria or quantum evolution.
PALEOZOIC LYCOPSID FRUCTIFICATIONS.
TLDR
Additional evidence concerning the 3-dimensional sporophyll structure of this one species of Lepidocarpon and the configurations obtained by certain planes of section through it have served to demonstrate that Illiniocarpo cadyi is in reality a taxon based on sectioned structures of the sporophyLL of this LepidOCarpon species.
Notes on the Lepidocarpaceae
TLDR
The purpose of this paper is to call attention to some of the bio-characters which appear to be important in distinguishing lepidocarp genera but which have not been given equal consideration by different authors, leading to some ambiguities and conflicting conclusions.

In 1849, when M. Brongniart published his ‘Tableau des genres des Végétaux Fossiles,’ he admitted into his series of Acrogenous Cryptogams a family of Lepidodendra, in which he included
On the Megagametophytes of Two Lepidodendracean Cones
TLDR
This study provides further evidence of a close phylogenetic relationship between the lepidodendrids and the extant genus Isoetes.
Chronospecies' longevities, the origin of genera, and the punctuational model of evolution
TLDR
Estimates of rates of extinction suggest that the bottleneck effect cannot be a major source of evolutionary change, and the long durations of hominid species imply that the evolution of humans, like that of other mammals, conforms to this model.
Pennsylvanian System of the Mid-Continent
The Pennsylvanian System in the Mid-Continent area consists of five series, from the lowest upward--the Morrowan, Atokan, Desmoinesian, Missourian, and Virgilian. In the Arkoma basin the
Fossil Plants and Coal: Patterns of Change in Pennsylvanian Coal Swamps of the Illinois Basin
TLDR
Coal palynology and studies of petrified peat indicate major changes in coal-swamp floras and the botanical constituents of coal throughout Pennsylvanian time, including the change from a lycopod-dominated flora to one in which tree ferns were the major element.
