Systematics of the Carex aquatilis and C. lenticularis lineages: Geographically and ecologically divergent sister clades of Carex section Phacocystis (Cyperaceae).
Carex aquatilis is a highly diverse and geographically widespread member of one of the largest genera of flowering plants, Carex, and is ideally suited for the study of the role of hybridization and niche partitioning in ecological speciation. Phylogenetic analyses of nuclear ITS and ETS 1f and chloroplast psbA-trnH DNA sequences support the monophyly of a broadly defined Carex aquatilis-Carex ...
متن کاملThe 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, the relationship of the reduced sect. Phyllostachys to 12 putatively related sections, representing all four subgenera (Primocarex, Indocarex, Carex, Vignea), was inferred from sequences of the ITS (internal t...
متن کاملCarex jianfengensis (Carex sect. Rhomboidales, Cyperaceae), a New Species from Hainan, China
A new species of Carex sect. Rhomboidales, C. jianfengensis, is described and illustrated from Hainan, China. The new species is similar to C. zunyiensis but differs in having involucral bracts sparsely hispid and with ca.1 cm long sheaths; inflorescence with 4 spikes, terminal spike ca. 2.5 cm long, lateral spikes 2-3.5 × 0.7-1 cm; staminate glumes narrowly ovate, ca. 5 mm; pistillate glumes t...
متن کاملEvolution in sedges (Carex, Cyperaceae)
REZNICEK, A. A. 1990. Evolution in sedges (Carex, Cyperaceae). Can. J. Bot. 68: 1409-1432. Carex is the largest and most widespread genus of Cyperaceae, but evolutionary relationships within it are poorly understood. Subgenus Primocarex was generally thought to be artificial and derived from diverse multispicate species. Relationships of rachilla-bearing species of subgenus Primocarex, however,...
متن کاملFourteen polymorphic microsatellite markers for a widespread limestone endemic, Carex eburnea (Cyperaceae: Carex sect. Albae)1
PREMISE OF THE STUDY Microsatellite primers were developed for a widespread limestone endemic sedge, Carex eburnea, to facilitate investigation of the genetic diversity and phylogeography of this taxon and its closest relative, C. mckittrickensis. METHODS AND RESULTS Forty-eight primer pairs were designed from Illumina sequence data and screened for suitability. Fourteen of these primer pairs...
