Common Name The Early Diuris [refers to its early bloom time]

Flower Size .8 to 1.2" [2 to 3 cm]

Found in Western Australia at elevations around 500 meters as a to medium sized, cold growing terrestrial with 2 to 3, basal, semi-erect to lax, conduplicate, linear to linear-lanceolate, bright green, acute to acuminate, often recurved, basally clasping leaves that blooms in the early winter on an erect, slender, green, 6 to 14" [15 to 35 cm] long, 1 to 4 flowered inflorescence with sometimes a basal, extended, leaf-like bract

This species is similar to D brumalis but differs in having a shorter habit [to 35 cm tall], up to four flowers [D brumalis has up to 15], recurved lateral sepals [they are straight in D brumalis], a larger labellum with a broadly cuneate midlobe about as long as the lateral lobes, and its distribution is farther to the north.
