Polyploid and hybrid evolution in roses east of the Rocky Mountains.
This study investigates the impact of hybridization and polyploidy in the evolution of eastern North American roses. We explore these processes in the Rosa carolina complex (section Cinnamomeae),Expand

Phylogenetic Relationships in the Genus Rosa: New Evidence from Chloroplast DNA Sequences and an Appraisal of Current Knowledge
Abstract The genus Rosa (roses) comprises approximately 190 shrub species distributed widely throughout the temperate and subtropical habitats of the northern hemisphere. Despite numerous recentExpand

Phylogeny of Cyperaceae based on DNA sequence data - a new rbcL analysis
Since the Monocots II meeting in 1998, significant new data have been published that enhance our systematic knowledge of Cyperaceae. Phylogenetic studies in the family have also progressed steadily.Expand

Phylogeny and Evolution in Cariceae (Cyperaceae): Current Knowledge and Future Directions
The goal of this study was to review the impact of DNA sequence analyses on our understanding of Cariceae phylogeny, classification and evolution. To explore character evolution, 105 taxa from fourExpand

Phylogenetic Relationships in Tribe Cariceae (Cyperaceae) Based on Nested Analyses of Four Molecular Data Sets
Phylogenelic reconstruction for Carex and relatives in tribe Cariceae is complicated by species richness and nearly cosmopolitan distribution. In this investigation, our main objective was toExpand

Plant DNA barcodes and species resolution in sedges (Carex, Cyperaceae)
We investigate the species discriminatory power of a subset of the proposed plant barcoding loci (matK, rbcL, rpoC1, rpoB, trnH‐psbA) in Carex, a cosmopolitan genus that represents one of the threeExpand

The phylogenetic position of Carex section Phyllostachys and its implications for phylogeny and subgeneric circumscription in Carex (Cyperaceae).
Wide speculation surrounds the origin and phylogenetic relationships of the most highly reduced sections in the genus Carex. In order to gain a better understanding of phylogeny in Carex, theExpand

Biogeography of the cosmopolitan sedges (Cyperaceae) and the area‐richness correlation in plants
Aim Across angiosperm families, the area occupied by a family is strongly correlated with its richness. We explore the causes of this area-richness correlation using the cosmopolitan family,Expand

Phylogeny of Carex subg. Vignea (Cyperaceae) Based on Non-coding nrDNA Sequence Data
Abstract Carex subg. Vignea is characterized by sessile bisexual spikes, distigmatic flowers, and the lack of cladoprophylls. Phylogenies reconstructed using nrDNA internal and external transcribedExpand
