Agrostophyllum carex derived its name for the resemblance in habit to some members of the sedge genus Carex L. This species seems to lack close relatives. It is easily recognised by its slender sedge-like habit, ovate-elliptic epichile of the lip, and the stout column with a large appendage below the stigma.
