Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Threat status:Victoria: endangered (e)

Flowering stem slender, 10–15 cm tall. Leaf-blade to 10 cm long, 1–2 mm diam. at base, apex erect. Flowers 5–8, small, reddish brown, sweetly perfumed, in a narrow spike 3–5 cm long; ovary obovoid, to 3.5 mm long; sepals 3.5–4.5 mm long, dorsal sepal ovate-lanceolate, lateral sepals free, ovate-lanceolate, recurved, parallel; petals linear, 3–4 mm long. Labellum subsessile, c. 3 mm long, porrect at base, reflexed at about right-angles near middle, lamina reddish, margins irregular; callus plate prominently raised, broad at base then tapered, extending well beyond labellum bend. Column appendages oblong, c. 1 mm long. Flowers Oct.–Nov.

Largely, if not entirely confined to far south-western Victoria on calcareous sandy soils in near-coastal heath and heathy woodland (see following note).

Currently known only from a few old collections from the lower Glenelg River, Mt Richmond N.P. and Bats Ridges and possibly critically endangered or extinct. A collection from near Hamilton (Yatchaw, 1965), probably from grassland, appears to be this entity, but the specimen is rather taller (c. 30 cm high) and the habitat quite different.

Apparently flowering is stimulated by fire.
