Victorian Naturalist 46: 179, t. 7 (1930) APNI

Taxonomic status:Accepted

Occurrence status:Extinct

Establishment means:Native

Threat status:EPBC: vulnerable (VU); Victoria: extinct (x); listed in Flora and Fauna Guarantee Act 1988

Flowering stem 10–25 cm tall. Leaf-blade usually senescent at flowering time, to 16 cm long, 4–10 mm diam. at base, apex lax. Flowers 50–80, greenish suffused with purple, fragrant, in a dense narrow-cylindric spike 4–10 cm long, perianth expanding widely; ovary ovoid, turgid, 3–4 mm long, erect; sepals greenish, 4–5 mm long, dorsal sepal broadly ovate, lateral sepals free, narrow, divergent; petals similar to sepals, recurved, obtuse. Labellum small, cordate, to 4 mm long, recurved almost from base, lamina flat, purplish or pink, margins crenate or undulate; callus plate deep purplish, triangular, papillate, with a prominent v-shaped ridge extending nearly to labellum apex. Column appendages ovate, to 1.5 mm high, obtuse. Flowers Oct.–Nov.

Also NSW. Restricted to sub-alpine meadows or open Snow Gum woodland and very rare in Victoria. Flowers Nov.-Dec. Known only from the Eastern Highlands of Victoria in the vicinity of Cobungra, on a sunny ridge in clay soil.

All known collections were made at a single site on 3 occasions prior to 1933 and the species is probably now extinct.

Very distinctive by virtue of its many widely opening flowers in a dense inflorescence. Similar in appearance to P. retroflexum but that species has a smooth labellum callus.
