Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Threat status:Victoria: endangered (e)

Flowering stem 10–25 cm tall. Leaf-blade usually senescent at flowering time, to 15 cm long, 2–3 mm diam. at base, apex lax. Flowers 10–40, greenish suffused with pink or purple, lemon-scented, in a dense narrow-cylindric spike 5–8 cm long, perianth expanding widely; ovary obovoid, turgid, 3–4 mm long, at about 30 deg. to the rachis; sepals 5–6 mm long, dorsal sepal ovate-lanceolate, lateral sepals free, linear-lanceolate, parallel or slightly divergent; petals 5–6 mm long, spreading widely, tips recurved, apex sub-acute to obtuse. Labellum broadly ovate-lanceolate, 4–4.5 mm long, erect, recurved in distal half, pink to purplish, distal margins slightly crenulate; callus plate green, raised, fleshy, smooth, channelled, extending nearly to labellum apex. Column appendages linear-oblong, to 1.8 mm long, obtuse. Flowers Nov.–Dec.

SnM. Also NSW. In Victoria, known only from a single population on the Nunniong Plateau in sub-alpine herbfield.

Distinctive by virtue of its widely opening flowers in a dense inflorescence. Similar in appearance to Prasophyllum morganii and regarded by some as probably conspecific with it (P. morganii then being the correct name). Prasophyllum morganii, when maintained as distinct, has an even denser inflorescence than that of P. retroflexum, with more flowers and a papillate labellum callus.
