Phylogenetic Relationships and Taxonomic Status Of the Paleoendemic Fagaceae Of Western North America: Recognition Of A New Genus, Notholithocarpus

  title={Phylogenetic Relationships and Taxonomic Status Of the Paleoendemic Fagaceae Of Western North America: Recognition Of A New Genus, Notholithocarpus},
  author={Paul S Manos and Charles H. Cannon and Sang-Hun Oh},
Abstract We investigated the phylogenetic relationships and taxonomic status of the castaneoid component (Lithocarpus and Chrysolepis) of the family Fagaceae that is endemic to the California Floristic Province (CA-FP). Over 7800 basepairs of nuclear and chloroplast DNA were analyzed in 17 taxa representing the breadth of phylogenetic diversity in the family. The genus Lithocarpus, as currently defined, is clearly polyphyletic due to the inclusion of L. densiflorus. Here, we designate this… 
Revised circumscription of Nothofagus and recognition of the segregate genera Fuscospora , Lophozonia , and Trisyngyne (Nothofagaceae)
A new phylogenetic analysis of morphological characters is presented and it is argued that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Noth ofagus with four subgenera.
Chloroplast Genome of Lithocarpus dealbatus (Hook.f. & Thomson ex Miq.) Rehder Establishes Monophyletic Origin of the Species and Reveals Mutational Hotspots with Taxon Delimitation Potential
The chloroplast-based phylogenetic analysis among the Quercoideae established a monophyletic origin of Lithocarpus, and a closer evolutionary lineage with a few Quercus species, and identified five mutational hotspots having high taxon-delimitation potential across four genera of Quer coideae.
Evolutionary trends and ecological differentiation in early Cenozoic Fagaceae of western North America.
UNLABELLED • PREMISE OF THE STUDY The early Cenozoic was a key period of evolutionary radiation in Fagaceae. The common notion is that species thriving in the modern summer-dry climate of
Two new Castanopsis (Fagaceae) species based on cupule and foliage from the upper Miocene of eastern Zhejiang, China
Two new species are described from fossil specimens collected from the upper Miocene Shengxian Formation, Zhejiang Province, Southeast China, where Castanopsis praeouonbiensis and C. praefissa became extinct in this area because of the cooling climate from the late Miocene to the present day in Zhe Jiang Province.
Fagaceae in the Eocene Palynoflora of the South of Primorskii Region: New Data on Taxonomy and Morphology
Abstract Dispersed fossil pollen grains of Fagaceae from the Eocene sediments of the south of Primorskii Region have been analyzed using a scanning electron microscope. Fourteen types of Fagaceae
Wood Anatomy of Modern and Fossil Fagales in Relation to Phylogenetic Hypotheses, Familial Classification, and Patterns of Character Evolution
The wood anatomy of fagalean families is summarized. Each family and most genera are wood anatomically distinct and can be distinguished by features such as vessel grouping and arrangement,
The first report of an ‘evergreen Castanopsis type’ wood (Fagaceae) for the Late Miocene–Early Pliocene of Europe (Bulgaria, Blagoevgrad Graben)
In the present article, the establishment of the species Castanopsis: C. bulgarica Mantzouka, Ivanov, and Bozukov is proposed after the study of a new fagaceous fossil wood stem discovered in 2016
Plastome data reveal multiple geographic origins of Quercus Group Ilex
High plastid divergence in members of Quercus Group Ilex, including haplotypes shared with related, but long isolated oak lineages, point towards multiple geographic origins of this group of oaks and a strong geographic sorting in the focal group and the genus that is entirely decoupled from species boundaries is found.
Cretaceous and Paleogene Fagaceae from North America and Greenland: evidence for a Late Cretaceous split between Fagus and the remaining Fagaceae
The studied assemblages confirm that the Fagus lineage (= Fagoideae) and the remainder of modern Fagaceae were diverged by the middle Late Cretaceous, together with the extinct Fagalid lineage(s) of Eotrigonobalanus and the newly recognised genus Paraquercus, and a unique pollen morph with similarities to both EOTrigonabalanus and Quercus.
Staminate inflorescences with in situ pollen from Eocene Baltic amber reveal high diversity in Fagaceae (oak family)
Abstract: Eocene Baltic amber forms the largest amber deposit worldwide; however, its source vegetation and climate are much debated. Representatives of the oak family (Fagaceae) were abundant in the


Molecular phylogenetics and cupule evolution in Fagaceae as inferred from nuclear CRABS CLAW sequences
This work used CRABS CLAW, a single-copy nuclear gene, to generate over 2,900 base pairs of new sequence data, and combined it with previously collected molecular data to examine morphological evolution in the Fagaceae, and proposed a new hypothesis to explain the evolution of the unusual cupules of Asian Lithocarpus and Chrysolepis.
Analysis of cupule morphology in Fagaceae provides an interpretation of evolution in cupules which differs substantially from Forman's interpretation, and interprets trigonobalanoid cupules as indicative of an ancestral type of inflorescence within Fagidae.
Earliest megafossil evidence of Fagaceae: phylogenetic and biogeographic implications
Fossil evidence of Fagaceae from the Paleocene/Eocene boundary of western Tennessee is described and discussed. These fossils include a newly discovered pistillate inflorescence and dispersed fruits
Paleobotanical studies in Fagaceae of the European Tertiary
A systematic reassessment of megafossil records of Fagaceae in Central Europe has been undertaken on the basis of leaf cuticular characters, finding that ancient taxa (except in Fagus lineage), are gradually replaced by deciduous species of Quercus and Castanea.
Generic delimitation in the Castaneoideae (Fagaceae)
It has become clear that Castanopsis and Lithocarpus are derived from two distinct evolutionary lines, and it is therefore highly desirable to maintain these genera as distinct, even though in practice it still remains impossible to separate them completely in a key.
Systematics of Fagaceae: Phylogenetic Tests of Reproductive Trait Evolution
Combined analysis provided some evidence for a relationship of Quercus to Lithocarpus and Chrysolepis, taxa with dichasially arranged pistillate flowers, where each flower is surrounded by cupular tissue, which indicates that a more broadly defined flower cupule may have a single origin.
The Bornean Lithocarpus Bl. section Synaedrys (Lindl.) Barnett (Fagaceae): its circumscription and description of a new species.
The Bornean species of Lithocarpus Bl. section Synaedrys (Lindl.) Barnett (Fagaceae) are discussed in terms of their unifying characteristics, and keys to the species are provided. A novel
Cascadiacarpa spinosa gen. et sp. nov. (Fagaceae): castaneoid fruits from the Eocene of Vancouver Island, Canada.
The appearance of Casacadiacarpa in the Eocene of British Columbia supports a Paleogene radiation of the Fagaceae family, and the numerous derived characters of these fruits show that evalvate, spiny, single-fruited cupules of Fag Families were present in the Paleogene of North America.
Phylogenetic analyses of "higher" Hamamelididae based on plastid sequence data.
The basal position of Nothofagus within the matK tree is consistent with the fossil record of "higher" hamamelids in which Noth ofagus pollen appears earlier than microfossils with affinities to other modern " Higher Hamamelididae.
The Use of Geological and Paleontological Evidence in Evaluating Plant Phylogeographic Hypotheses in the Northern Hemisphere Tertiary
The history of the climatic and geographic features of the Tertiary of the Northern Hemisphere agrees with many phylogenetically based phylogeographic hypotheses of living angiosperm genera but indicates that some hypotheses require reanalysis.
