A new classification and linear sequence of the gymnosperms based on previous molecular and morphological phylogenetic and other studies is presented. Currently accepted genera are listed for each family and arranged according to their (probable) phylogenetic position. A full synonymy is provided, and types are listed for accepted genera. An index to genera assists in easy access to synonymy and family placement of genera. 
A linear sequence to facilitate curation of herbarium specimens of Annonaceae
A linear sequence of four subfamilies, 15 tribes and 106 genera of the magnoliid family Annonaceae is provided, based on state-of-the-art and stable phylogenetic relationships, which facilitates the organisation ofAnnonaceae herbarium specimens.
A linear classification of Cyperaceae
This paper provides a linear classification of two subfamilies, 24 tribes, 10 subtribes and 95 genera of the monocot family Cyperaceae (Poales), based on a stable phylogenetic framework resulting
An Update of the Family-Level Taxonomy of Vascular Plants in Mongolia
A new comprehensive checklist of Mongolian vascular plant families includes descriptions of all accepted plant families, each with a basionym, homonym and full list of synonyms. The list is a
An updated checklist of Indian western Himalayan gymnosperms and lectotypification of three names
An updated checklist of gymnosperms of the western Himalaya situated within political boundaries in India is provided along with conservation status and distribution.  Lectotype for three names viz.,
A systematic classification of Ephedraceae: living and fossil
A new systematic classification of the family Ephedraceae is proposed at the generic level based on the reduction and sterilization evolutionary hypothesis of female reproductive organs, and ten genera are included in the new classification.
An updated checklist of the vascular flora native to Italy
Abstract An updated inventory of the native vascular flora of Italy, providing details on the occurrence at regional level, is presented. The checklist includes 8195 taxa (6417 species and 1778
Cladistic analysis of Taxaceae s. l.
Taxaceae s. l. is a wider concept of classification treating five genera of Taxaceae s. str. and Cephalotaxus together. Cephalotaxus is morphologically very similar to the five genera of Taxaceae s.
Gymnosperm: A Review
Gymnosperms are the plants of evolutionary importance from Mesozoic era to till now and due to rapid change in the anthropogenic activities this remarkable group of the plants is now at the line of extinction, now a very few plants are exist which are the representative of the group.
Epiphyte Taxonomy and Evolutionary Trends
A bibliometric analysis shows that the ecological literature of the last 120 years has been highly biased toward a few taxonomic groups and particular regions and all conclusions in following chapters will inevitably carry this bias.
Taxonomy and Classification
This chapter provides a description of all plant families and genera that include putative fully mycoheterotrophic species, excluding initial and partial mycoheterotrophs. The overview covers a total


The Linear Angiosperm Phylogeny Group (LAPG) III: A linear sequence of the families in APG III
The publication of the third Angiosperm Phylogeny Group (APG) classification has resulted in the need for a revised systematic listing of the accepted families, and this linear APG III (LAPG III) sequence of families is presented here.
The Phylogeny of the Podocarpaceae Based on Morphological Evidence
A cladistic analysis of morphological evidence resulted in one most parsimonious tree, with Saxegothaea as sister group to other genera, supporting the recognition of segregate genera in the coniferous family Podocarpaceae.
A phylogenetic classification of the land plants to accompany APG III
A formal classification of the land plants that is compatible with the APG III classification is proposed, and two new names are established: Amborellanae and Austrobaileyanae.

Inferences of plesiomorphic character states within the family are largely consistent between analyses and support the view that prototypical podocarps had bifacial leaves, cones with several fertile cone scales, and large epimatia (cone scales) that covered the inverted ovules.
Interspecific relationships and origins of Taxaceae and Cephalotaxaceae revealed by partitioned Bayesian analyses of chloroplast and nuclear DNA sequences
The results confirm, on a basis of multiple molecular markers and a complete sampling of basic species, the suggested monophyly of Taxaceae and Cephalotaxaceae and propose interspecific relationships within each group, with profound nomenclatural and taxonomic implications.
Araucariaceae (Pinopsida): Aspects in palaeobiogeography and palaeobiodiversity in the Mesozoic
The circumscription and phylogenetic relationships of Callitropsis and the newly described genus Xanthocyparis (Cupressaceae).
An analysis of ITS (nrDNA), matK, and rbcL sequence data in combination with 58 informative morphological characters was aimed at testing the monophyly of the remainder of Chamaecyparis and evaluating the placement and monophyle of Xanthocyparis.
Relationships within Cupressaceae sensu lato: a combined morphological and molecular approach.
Parsimony analysis of matK and rbcL sequence data, together with a nonmolecular database, yielded a well-resolved phylogeny of Cupressaceae sensu lato, and a new infrafamilial classification is proposed in which seven subfamilies are recognized.
Phylogeny of gymnosperms inferred fromrbcL gene sequences
Partial nucleotide sequences of the large subunit of ribulose-1,5-bisphosphate carboxylase (rubisco) gene (1333 base pairs: about 90% of the gene) from several seed plants indicate monophyly of gnetum group, which contradicts the results of morphological data.
