The species is endemic to Western Ghats (Taylor 1984, Cook 1996), India and found in Karnataka (South Kanara, Mangalore, North Kanara, and Udipi District, Kollur), North Kerala, Kasaragod, and Goa (Janarthanam and Henry 1992). Earlier known from its type locality and now recorded from Goa in north to Palghat District, Kerala in the south (Janarthanam and Henry 1992).
It is a small annual herb found in seasonally flooded places, wet soil over laterite and in wet grassland (Cook 1996). It sprouts up immediately after rains in wet or water-logging places over laterite rocks, grasslands and rarely on soil-covered black boulders (Janarthanam and Henry 1992).
