Nucleotide sequences of a chloroplast rDNA region including 8 bp from the 3" end of 23S rDNA–ITS2–4.5S rDNA–ITS3–5S rDNA–ITS4 (approximately 800 bp) were determined in 25 species of Lycopodiaceae and two species of the genus Isoetes. The rate of molecular evolution of spacers significantly varied in different Lycopsida taxa. A phylogenetic analysis by the neighbor-joining (NJ) method revealed that the family Lycopodiaceae is monophyletic. The topology of phylogenetic trees suggests the…

Phylogenetic relationships of New Zealand Lycopodiaceae
TLDR
Several New Zealand species showed intraspecific genetic variation within New Zealand and/or compared to conspecific samples from overseas, and the chloroplast sequences could not distinguish Lycopodiella diffusa and Lycopdiella lateralis, nor the different morphologies of Phlegmariurus varius characteristic of high and low altitudes.
A molecular phylogenetic study of Huperziaceae based on chloroplast rbcL and psbA-trnH sequences
TLDR
Phylogenetic relationships within Huperziaceae were studied using chloroplast rbcL gene and psbA-trnH intergenic spacer sequences and it was found that Phleg- mariurus is derived from Huperzia.
DNA content variation in monilophytes and lycophytes: large genomes that are not endopolyploid
TLDR
Using flow cytometry, genome size and degree of endopolyploidy were estimated for 37 species and there was no indication of endoreduplication in any of the leaf, stem, or root tissue analyzed.
Morphological and molecular analyses of fungal endophytes of achlorophyllous gametophytes of Diphasiastrum alpinum (Lycopodiaceae).
TLDR
This study suggests a fungus belonging to Sebacinales group B as the main fungal host of the D. alpinum gametophytes, which would explain the steady association of these plants.
Molecular phylogeny and the biogeographic origin of East Asian Isoёtes (Isoёtaceae)
TLDR
The phylogenetic reconstruction of East Asian Isoёtes species suggests an Australian origin for the East Asian species that arose through long-distance dispersal during the late Oligocene.
New and existing combinations in Palaeotropical Phlegmariurus (Lycopodiaceae) and lectotypification of the type species Phlegmariurus phlegmaria (L.) T.Sen & U.Sen.
Abstract The genus Phlegmariurus Holubis recognised more widely than originally proposed and is circumscribed to include both Neotropic and Palaeotropic epiphytic and terrestrial species of
Patterns and biological implications of DNA content variation in land plants
TLDR
Two measures of DNA content were examined in taxa across the land plant phylogeny: genome size and endopolyploidy (or endoreduplication index, EI) and the relationships between DNA content and various morphological and ecological traits were assessed.
Flow cytometry confirms reticulate evolution and reveals triploidy in Central European Diphasiastrum taxa (Lycopodiaceae, Lycophyta).
TLDR
Diploid hybrids have retained their genetic and morphological identites throughout their Central European range, and thus no indications for diploid backcrossing were found.
[Sporogenesis, sporoderm and mature spore ornamentation in Lycopodiaceae].
TLDR
A comparative analysis of the sporogenesis ultrastructure showed that the sporocyte coat is largely composed by primary wall components; the sporocytes develop much of their metabolic activity in the production of their coat, which is retained until the spores release; protective functions for the diploid cells undergoing meiosis is postulated here for this layer.

Molecular evolution of pteridophytes and their relationship to seed plants: Evidence from complete 18S rRNA gene sequences
TLDR
The molecular data indicate that lycopsids are monophyletic and are the earliest diverging group within the vascular land plants, whereasPsilotum nudum is more closely related to the seed plants than to other pteridophyte lineages.
Evolution of Lycopodiaceae (Lycopsida): estimating divergence times from rbcL gene sequences by use of nonparametric rate smoothing.
TLDR
The analysis shows that, although much living species diversity stems from relatively recent cladogenesis, the origins of the family and generic crown groups are much more ancient events.
Noncoding sequences from the slowly evolving chloroplast inverted repeat in addition to rbcL data do not support gnetalean affinities of angiosperms.
TLDR
Results of phylogenetic analyses provide very strong bootstrap support for monophyly of both spermatophytes and angiosperms and for a basal position for the aquatic angiosperm Nymphaea among angios perms studied was observed.
Phylogeny of epiphytic Huperzia (Lycopodiaceae): paleotropical and neotropical clades corroborated by rbcL sequences
TLDR
Together, these two molecular studies provide strong evidence that the diversification of epiphytic Huperzia is a comparatively recent phenomenon (Late Cretaceous-Tertiary), and that there has been widespread morphological convergence in Epiphytes throughout the tropics.
Relationships of Lycopodium and Lycopodiella Based on Combined Plastid rbcL Gene and trnL Intron Sequence Data
TLDR
An evaluation of biogeographic and phylogenetic patterns in these two genera shows a striking difference from that in Huperzia, where Sections within Lycopodium and Lycopodiella have broad geographic distributions, whereas molecular data partition the much larger HuperZia group into predominantly neotropical and paleotropical clades.
Phylogeny of Lycopodiaceae (Lycopsida) and the Relationships of Phylloglossum drummondii Kunze Based on rbcL Sequences
TLDR
A cladistic analysis based on rbcL sequences from a representative sample of 12 species yields a single most parsimonious tree that supports monophyly of Lycopodiaceae, Lycopodium, and Lycopodiella, providing the first clear evidence for the relationships of the problematic Phylloglossum drummondii.
The Young Gametophyte of Phylloglossum (Lycopodiaceae)
Any similarities between Phylloglossum and specific subgenera of Lycopodium sens. lat. have been difficult to determine, because the reduced sporophyte of Phylloglossum has few characters for
Epiphytism and terrestrialization in tropicalHuperzia (Lycopodiaceae)
TLDR
A phylogenetic analysis of Huperzia (Lycopodiaceae) documents a single origin of epiphytism and multiple reversals to a terrestrial habit in the Neotropics, indicating that long distance, transoceanic dispersal is rare in these homosporous plants — accounting for less than 5% of species distributions — and that convergence in strobilus and branch morphology is widespread among Paleotropical and NeotropicalEpiphytes.
