It is an epiphytic orchid that forms long-lasting clumps of grass-like leaves. Up to fifty crowded olive green to dark or brownish green flowers are borne on an arching flowering stem. Of the three Australian species of Cymbidium, this is the only one that does not have prominent pseudobulbs. It is found in eastern Australia, usually growing in the hollows of old or fallen, decaying trees.
