Gahnia filum, the chaffy saw-sedge, is a tussock-forming perennial in the family Cyperaceae, endemic to Australia. It grows to between 60 and 110 cm in height.[2]
The species occurs in coastal salt marsh in the states of New South Wales, Victoria, Tasmania and South Australia.[2][3]
The caterpillar of the Altona Skipper butterfly uses this species for shelter during daylight hours, binding the leaves with silk. By night it feeds on the grass.[4]
