Abstract Despite the controversy surrounding Cariceae generic and Carex subgeneric limits, most debates centre on a relatively small number of highly reduced unispicate taxa. This study examines Cariceae phylogeny by using all five genera (Schoenoxiphium, Kobresia, Uncinia, Carex, Cymophyllus) and four Carex subgenera (Psyllophora, Vignea, Vigneastra, Carex), with the emphasis of sampling on the tribe's taxonomically difficult unispicate groups (Uncinia, Cymophyllus, Kobresia pro parte, Carex…

The results indicate that this inflorescence type has evolved multiple times and is derived within subg.

Searching for the sister to sedges (Carex): resolving relationships in the Cariceae-Dulichieae-Scirpeae clade (Cyperaceae)

Using the plastid genes matK and ndhF and a greatly improved taxonomic sampling, analyses firmly position Dulichieae and Khaosokia (79% and 85% bootstrap support) as successive sisters to a clade consisting of five major lineages, including Cariceae, sister to the Trichophorum clade.

Phylogeny and Evolution in Cariceae (Cyperaceae): Current Knowledge and Future Directions

Character analyses indicate that inflorescence proliferation and reduction have occurred in all major clades, and that the Cariceae’s unisexual flowers have evolved from perfect flowers.

A Five Gene Phylogenetic Study of Fuireneae (Cyperaceae) with a Revision of Isolepis humillima

Maximum parsimony, maximum likelihood and Bayesian analyses of the dataset strongly support Fuireneae as a grade of three clades, and it is suggested that a large-scale revision of tribal limits is required to reflect the natural relationships of the genera currently treated in Fuirenae.

Phylogeny of Carex subg. Vignea (Cyperaceae) Based on Amplified Fragment Length Polymorphism and nrDNA Data

Abstract Carex subg. Vignea is a distinctive taxon characterized by sessile, bisexual inflorescence units, distigmatic flowers, and the lack of cladoprophylls. Evolutionary relationships within

Phylogeny of Cyperaceae Based on DNA Sequence Data: Current Progress and Future Prospects

The phylogenetic position of 40 species in 21 genera is presented in this study for the first time, elucidating their position in Abildgaardieae (Trachystylis), CryptangIEae (Didymiandrum, Exochogyne), Cypereae (Androtrichum, Volkiella), Eleocharideae (Chillania), and Schoeneae (Calyptrocarya, Morelotia).

Evolution in Carex L . sect . Spirostachyae ( Cyperaceae ) : A molecular and cytogenetic approach

Two main groups with different chromosome numbers and edaphic preferences are identified in the core Spirostachyae, and the geographical barrier of the Strait of Gibraltar has played different roles in the course of evolution of this section.

Phylogenetic Relationships in Cariceae (Cyperaceae) Based on ITS (nrDNA) and trnT-L-F (cpDNA) Region Sequences: Assessment of Subgeneric and Sectional Relationships in Carex with Emphasis on Section Acrocystis

A molecular phylogenetic study employing nrDNA ITS and cpDNA trnT-L-F spacer sequences assesses relationships within Carex section Acrocystis and identifies a monophyletic group for more detailed study, suggesting that Cymophyllus, Kobresia, Schoenoxiphium, and Uncinia are nested within carex.

Molecular Systematics of Cyperaceae Tribe Cariceae Based on Two Chloroplast DNA Regions: ndhF and trnL Intron-intergenic Spacer

The results indicate that genus Carex is paraphyletic with respect to Kobresia, Cymophyllus, and Uncinia, and several unispicate Carex species, and a monophyletic Cariceae with 100% bootstrap support is revealed.

The phylogenetic position of Carex section Phyllostachys and its implications for phylogeny and subgeneric circumscription in Carex (Cyperaceae).

Phylogenetic theories inferred from the presence or abnormal growth of the rachilla were not supported by tree topologies, and difficult sectional circumscriptions, such as the separation of sections Laxiflorae and Careyanae, were strongly upheld by sequence data.

Evolution in sedges (Carex, Cyperaceae)

The often suggested connection between Uncinia and unispicate Carex is shown, based on rachilla morphology, to be founded on incorrect interpretation of homology.

The morphological variation within the species suggests separation of taxa below specific level, or perhaps even at species level, but this will require more detailed information about the ecology, distribution and the cytology.
