Fimbristylis dura is a perennial grass-like plant with short, rarely creeping, woody rhizomes. They are commonly found in marshy areas in the evergreen forests of eastern Asia.[1]
Fimbristylis dura belongs to the family Cyperaceae, commonly known as the sedge family. It is a herbaceous perennial species, with its flowering and fruiting occurring from July to March. The plant is primarily distributed in the Indian state of Kerala, particularly in districts such as Palakkad, Idukki, Kollam, and Thiruvananthapuram. Globally, it is found in the Indo-Malaysian region.[2]
Fimbristylis dura is characterized by its perennial nature and short rhizomes. Its stems are solitary or form tufts, reaching heights of 40-50 cm, with acutely four-angled and rough surfaces. The leaves are flat, measuring 30–40 x 0.6 cm, and have a scabrid texture. The plant produces numerous spikelets that are elliptic, solitary, and peduncles, with brown ovate glumes. It is commonly found in open forests as well as along riverbanks and occasionally in rice fields, typically at elevations of up to 1,000 meters.[3]
Fimbristylis dura is occasionally harvested for local medicinal purposes, particularly for women after childbirth. Its distribution extends across East Asia, including southern China, India, Sri Lanka, Myanmar, Thailand, Vietnam, Malaysia, and Indonesia. In its habitat, it thrives in grassy areas within open forests, with occasional sightings in rice fields and along riverbanks, typically ranging from 5 to 600 meters above sea level.[4]
