Where in the world are Cyperaceae plants found?

Members of the Cyperaceae family are found on every continent except Antarctica. While these plants are distributed across Arctic, temperate, and tropical regions, the diversity of their genera is significantly higher in the tropics.1

Regarding their specific distribution:
* Global Presence: Many sedge species in northern latitudes exhibit circumpolar distributions. Conversely, species found in tropical or warm temperate regions are generally restricted to a single continent, unless they are widespread agricultural weeds.1
* Habitat Range: Sedges are ecologically diverse and occur in almost all habitats, excluding extreme deserts, marine environments, and deep-water ecosystems. They are most commonly found in sunny, moist, or wet environments, such as marshes, bogs, fens, meadows, and wet tundra. They also frequently appear in the understory of various temperate and tropical forests.1
* Genus-Specific Patterns: The largest genus, Carex, is found worldwide except in desert or semidesert regions, with high concentrations in the United States and eastern Asia. Other major genera, such as Cyperus, are primarily located in tropical and warm temperate regions.1
