Evolution 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 کاملNonuniform processes of chromosome evolution in sedges (Carex: Cyperaceae).
Holocentric chromosomes-chromosomes that lack localized centromeres-occur in numerous unrelated clades of insects, flatworms, and angiosperms. Chromosome number changes in such organisms often result from fission and fusion events rather than polyploidy. In this study, I test the hypothesis that chromosome number evolves according to a uniform process in Carex section Ovales (Cyperaceae), the l...
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 کاملTaxonomic Notes on Carex (Cyperaceae) of Austral South America
The name Carex poeppigii (sect. Echinochlaenae) is validated and a new combination in South American Carex, C. vixdentata (sect. Spirostachyae), is made here. Also, the taxonomic status of C. aueri is discussed, and this name is placed in the synonymy of C. reichei (sect. Arenariae).
متن کاملGermplasm evaluation in genus Carex of family Cyperaceae
To prepare a database of germplasm diversity in the Indian sedges, cytological studies were initiated on population basis from Punjab plains and adjoining areas. About 2000 taxonomical species have been recorded for major genus Carex but the cytological picture is quite dismal at the world level with chromosome records for only 579 species and 14 out of about 148 Indian species. The chromosome ...
