Carex
genus of plants
Carex is a vast genus of over 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges; however, those of genus Carex may be called true sedges. Carex is the most species-rich genus in the family. The study of Carex is known as caricology.
Description
All species of Carex are perennial, although some species, such as C. bebbii and C. viridula can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section.
The leaves of Carex comprise a blade, which extends away from the stalk, and a sheath, which encloses part of the stalk. The blade is normally long and flat, but may be folded, inrolled, channelled or absent.
The public source identifies “Carex” as genus of plants. This brief keeps that definition visible, then builds a research path around Carex, genus and plants.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Carex”, the useful work is to connect “genus of plants” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q158501. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
