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).

Plants growing in high-mountain environments may share common morphological features through convergent evolution resulting from an adaptative response to similar ecological conditions. The Carex flava species complex (sect. Ceratocystis, Cyperaceae) includes four dwarf morphotypes from Circum-Mediterranean mountains whose taxonomic status has remained obscure due to their apparent morphologica...

Schoenoplectiella erecta subsp. raynalii (Cyperaceae) is recorded for the first time from India and Asia. This taxon was collected in Ossudu Bird Sanctuary, Villupuram district of Tamil Nadu, southern India. Detailed description including microscopic study glume nutlets with digital images, morphological characters, habitat, key characters between two subspecies are provided.

Plants of the Carex genus (Family: Cyperaceae) have attracted recent attention as potential food additives due to their high levels of potential bioactive compounds. In this study, the stilbene contents of five unexplored Carex species were investigated: Carex capillacea, Carex hirta, Carex buchananii, Carex cuprina, Carex glauca. High-performance liquid chromatography coupled to mass spectrome...
