Said to be a synonym of Caladenia nana but I will leave it separate for now. Found in Western Australia in winter wet heath flats and swamps as a small to medium sized, cool to cold growing terrestrial orchid with a purple blotched, reddish beneath leaf that blooms spring on an erect, 6 to 16" [15 to 40 cm] long, 1 to 6 flowered inflorescence and carrying sweetly fragrant flowers
