These are between 20 and 70 millimetres in length and 2 to 9 millimetres in width, are hairless, and have an entire margin. The trivial name of the species, glaucum, refers to the greyish colour of the leaves. The scape is hairless, supporting a racemose arrangement of white or pink flowers that appear from January to May.The species is found on peaty sand in seasonally wet, low-lying areas such as swamps or other depressions. This triggerplant is associated with habitat dominated by sedges or Agonis.
