Cyperus species are monocotyledonous, perennial, potent, multipurpose medicinal plants which belongs to Cyperaceae family. These are commonly known as nagarmotha, nut grass, umbrella sedges and sweet sedges. The leaves, roots and tubers of these whole plant species are used in astringent, diuretic, diaphoretic, cordial, brodycardiac properties and used to treat more diseases therapeutically. Th...

We measured the effect of wet meadow vegetation on the bank strength and failure mechanics of a meandering montane meadow stream, the South Fork of the Kern River at Monache Meadow, in California’s Sierra Nevada. Streambanks colonized by ‘wet’ graminoid meadow vegetation were on average five times stronger than those colonized by ‘dry’ xeric meadow and scrub vegetation. Our measurements show th...

1 A ®eld experiment was designed to investigate the relationship between environmental heterogeneity and species diversity in a group of sedges (Cyperaceae: Carex) growing in old-growth forest. 2 A measure of environmental quality, as perceived by the sedges, was obtained from the survival of clonal ramets of 11 species of Carex planted at 10-m intervals along each of three 1-km transect lines....

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...

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 three largest plant genera on earth (c. 2000 species). To assess the ability of barcoding loci to resolve Carex species, we focused our sampling on three of the taxonomically best-known groups in the genus...

Abstract Background The paper by Tan and co-authors in this issue of Plant Soil explores feedback mechanisms between functional traits soil nutrient responses tiger nut ( Cyperus esculentus L.), with emphasis on their growth marginal agricultural lands. Scope Many the world’s top food species belong to order Poales, specifically family Poaceae. Cyperaceae, also are recognised for ecological imp...
