Gahnia trifida
Gahnia trifida, the coastal saw-sedge, is a tussock-forming perennial in the family Cyperaceae, endemic to southern Australia.
A herb, sedge or grass-like, with very rough leaf margins and underside. The species grows in dense tussocks, 1.5 metres and 1 metre across, with leaves over 1 metre long and drooping. It is found on white or grey sand, or clay, that may be saline. The leaf blade is inrolled from the margin on the upper surface. Stems are rigid and erect. Branchlets containing the flowering heads emerge from axils at the main bracts. This branchlet has a spike-like arrangement of numerous, yellow or brown, clusters of flowerheads.
