Rhus L. (sensu lato) has been considered the largest and most widespread genus in the Anacardiaceae. Controversy has surrounded the delimitation of the genus. Historically, seven segregate genera have been recognized: Actinocheita, Cotinus, Malosma, Melanococca, Metopium, Searsia, and Toxicodendron. These genera, together with Rhus s.str., are commonly referred to as the Rhus complex. Rhus s.str. includes two subgenera, Lobadium (ca. 25 spp.) and Rhus (ca. 10 spp.). Sequences of the internal… 
Phylogenetic analysis based on structural and combined analyses of Rhus s.s. (Anacardiaceae)
Structural data were combined with trnL-F and internal transcribed spacer sequences from other studies and with new sequences representing ten additional species to clarify the phylogenetic relationships of Rhus s.s.s and both subgenera, Rhus and Lobadium, are monophyletic.
Phylogenetic analysis of Toxicodendron (Anacardiaceae) and its biogeographic implications on the evolution of north temperate and tropical intercontinental disjunctions
The biogeographic results and the paleontological data support the Bering land bridge as the most likely route to explain the temperate disjunctions, yet the tropical disjunction in Toxicodendron seems to be best explained by the North Atlantic land bridge hypothesis.
Phylogeny of Rhus (Anacardiaceae) Based on Sequences of Nuclear Nia-i3 intron and Chloroplast TrnC-trnD
Incongruence among nuclear and chloroplast datasets, together with the phylogenetic positions, sympatric distributions, and morphological intermediacy of discordant taxa, suggest possible reticulate evolution among members of Rhus.
Phylogenetic Split of Malagasy and African Taxa of Protorhus and Rhus (Anacardiaceae) Based on cpDNA trnL–trnF and nrDNA ETS and ITS Sequence Data
A clade of Anacardiaceae subfamily Anacardioideae is investigated in order to clarify evolutionary relationships of the African-Malagasy members of these two genera, andylogenetic analysis of sequence data provides strong statistical support for polyphyly of Protorhus and monophyly of Rhus section Baronia.
Plastid genomes of the North American Rhus integrifolia-ovata complex and phylogenomic implications of inverted repeat structural evolution in Rhus L.
Rhus represents a promising novel system to study plastome structural variation of photosynthetic angiosperms at and below the species level, and variation at the inverted repeat boundary within Rhus was striking, resulting in major shifts and independent gene losses.
Morphological Features of Sumac Leaves (Rhus, Anacardiaceae), from the Latest Early Eocene Flora of Republic, Washington
Fossil Rhus leaves are diverse in the Eocene and demonstrate morphologies characteristic of hybrid leaves in this genus today, and provide additional evidence for possible hybridization and other evolutionary processes at play within the sumacs by the latest early Eocene in western North America.


Phylogeny of Cobaea (Polemoniaceae) based on sequence data from the ITS region of nuclear ribosomal DNA
The phylogenetic relationships of 16 of the 18 species of the neotropical genus Cobaea were investigated using sequences of the ITS1 and ITS2 regions of nuclear ribosomal DNA, suggesting that two of the three sections of Cobaea are not mono- phyletic; the third is monotypic.
Phylogeny and biogeography of Panax L. (the ginseng genus, araliaceae): inferences from ITS sequences of nuclear ribosomal DNA.
The Himalayas and central and western China are the current centers of diversity of the ginseng genus and the low ITS sequence divergence and a close relationship among species in that region suggest that rapid evolutionary radiation may have created such a diversity of Panax in the Himalaya and in central and eastern China.
Results support the hypothesis that sections Mitracarpium and Navarretia are monophyletic, with somewhat weaker support for a third monophylettic group consisting of sections Aegochloa and Masonia, and Evolutionary rate heterogeneity among sections is evident.
Sapindales:Molecular delimitation and infraordinal groups
A robust clade of core "sapindalean" taxa is identified that is sister to representatives of Malvales and there was no support for the recognition of the two more narrowly defined orders, Rutales and Sapindales sensu stricto.
Floral structure and evolution in the Anacardiaceae
Data from these sources, as well as from pericarp anatomy, wood anatomy and biflavonoid content indicate that the long standing intrafamilial classification into five tribes is artificial, and that the two small satellite families, Blepharocaryaceae and Julianiaceae should be included in the Anacardiaceae.
The major evolutionary trend in the heartwood flavonoid patterns was uniform in different populations, although the presence of 3',4'-dihydroxyflavone 4'-O-,8-glucoside varied in some taxa.
Pericarp structure and generic affinities in the Anacardiaceae
The occurrence of the Spondias-type in Canarium, a member of the sister group Burseraceae, suggests that this type is plesiomorphic in the Anacardiaceae, and the presence ofThe Anacardium- type in Blepharocarya and Orthopterygium Qulianiaceae further supports the inclusion of these taxa in the ANACardiaceae.

Some Aspects of Plant Geography of the Northern Hemisphere During the Late Cretaceous and Tertiary
Certain tentative conclusions can be drawn concerning ancient floristic relationships; combined with data derived from analyses of the present distribution of some angiosperm groups, hypotheses can be ventured, but many of these hypotheses require confirmation or rejection from future work.
