Found in South Africa in damp localities, often in moss at elevations of 500 to 1800 meters as a miniature, cold to cool growing terrestrial plant with dimorphic, imbricate to lax, lanceolate, almost completely sheathing leaves and grading into the numerous, linear radical leaves that blooms in the late spring and early summer on a termial, erect, 4 to 6 flowered, loosely corymbose raceme with narrow sheathing bracts that are shorter than the ovaries. They grow in colonies and really put on a show after a fire has been through.
