Rosette leaves on a separate plant, 3–5, narrowly ovate to lanceolate, 10–35 mm long, 4–8 mm wide. Flowers 1–10, 1.7–2.2 cm long, shiny, translucent green with dark green stripes and suffusions; dorsal sepal with a short apical point; lateral sepals deflexed, conjoined part narrow elliptic, 16–19 mm long, 7–8 mm wide, free points 3–4 mm long, parallel; petals slightly falcate, with a well-developed basal flange. Labellum oblong, 7–8 mm long, 3.5–4 mm wide, emerald green with a darker green basal mound and central stripe, occasionally brownish green, covered with numerous, short, transparent, bead-like cells, longer and hair-like at base and along margins, apex attenuate, notched.

CVU, DunT, Gold, GGr, HSF, LoM, MuM, NIS, VRiv, VVP, Wim. Also SA, NSW. Apparently localized in Victoria (e.g. outer north-eastern suburbs of Melbourne, Brisbane Ranges, Ararat), but exact range uncertain due to confusion with allied species. Grows in drier forests and woodlands on well-drained shallow clay loam.
