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).

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 کاملEnvironmental distribution of four Carex species (Cyperaceae) in an old-growth forest.
We conducted an in-depth characterization of the range of micro-environments (1 m) in which four Carex species (C. backii, C. communis, C. plantaginea, and C. platyphylla) grow in the understory of an old-growth, deciduous forest in southern Québec, Canada. All four species occurred in significantly different micro-environments. Carex plantaginea was found at the wet end of a moisture gradient,...

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).
