Cloud Sedge

Cloud sedge refers to Carex species in the family Cyperaceae adapted to high-altitude, cloud-bathed environments in montane and alpine regions worldwide. Several species bear this common name, including Carex nebulosa and related taxa from cloud forest zones and alpine grasslands in Africa, Asia, and the Americas. Sedges in these high-elevation habitats typically produce dense tussocks or spreading rhizomatous mats, contributing significantly to the structure of alpine meadows, cloud forest floors, and Andean páramo vegetation. Their triangular stems, grass-like leaves, and specialized female spikelets enclosed in flask-like perigynia are characteristic of the genus. Cloud sedges play important ecological roles in montane ecosystems: their dense root systems stabilize steep, moisture-laden soils prone to erosion, and their foliage provides food and cover for high-altitude invertebrates and small vertebrates. Carex species are among the most species-rich plant genera globally, with thousands of species distributed from arctic to tropical regions, and cloud forest sedges represent a particularly diverse and ecologically significant component of montane vegetation.
