The genus Carex L. of the family Cyperaceae is represented by 1,800–2,000 species.  It has a cosmopolitan distribution at high altitudes of the temperate and tropical regions (Mabberley 2008).  Hazra & Verma (1996) reported 62 species of Carex from Sikkim and the Darjeeling Himalaya.  During a survey of grasses in Kudremuk National Park, Karnataka (13.1690E & 75.2810N) a species of Carex was collected and confirmed as Carex phacota by using the floristic literature.  The genus Carex is characterized by a perennial rhizome, panicled spike, unisexual flowers rarely dioceses, glumes numerous, persistent and imbricate around the rachilla (Images 2 & 3).  Unisexual spikelets with one or two male florets at the tip and remaining female florets in the inflorescence, shortly beaked utricles are the key characters of Carex phacota (Gamble, 1928).  They usually grown on wetlands, stream sides or lakes; hence they are commonly called lakeshore sedge.  It is distributed in southern and eastern Asia, Bhutan, Nepal, China, Indonesia, Japan, Malaysia, Myanmar, Sri Lanka, northern Thailand, and Vietnam (Chowdary 2016).  In India it was first reported by Gamble in 1928 at Nilgiri Hills, Tamil Nadu; later from Assam, Chhattisgarh, Kerala, Meghalaya, Sikkim, West Bengal and now Karnataka also.  The herbarium is deposited in Central National Herbarium, Botanical survey of India, Howrah and also Herbaria, Department of Applied Botany, Kuvempu University, Shankaraghatta, Shivamogga, Karnataka (Image 4).

Flowering and Fruiting: November–March

Habitat and Ecology: Wet soil of grasslands, ditches, banks of streams and roadsides ditches at an altitude of up to 1,400m of shola (Image 1).
