Cyathochaeta is a genus of rhizomatous perennial sedges.
They have culms that are mostly noded. The leaves are mostly basal, often with one cauline and have ligule membranes. When flowering they produce a panicle-like, narrow inflorescence with distant nodes containing several spikelets at each node with a single bisexual flower.[1]
There are six known species all of which are endemic to Australia.[1]
The genera was first described in 1848 by the German botanist Christian Gottfried Daniel Nees von Esenbeck. List of species:
