Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Threat status:Victoria: rare (r)

Flowering plant 8–20 cm tall. Leaf oblong to oblong-lanceolate, 5–8 cm long, slightly hairy. Flower solitary, dark-blue to purplish; sepals and petals lighter coloured on the outside, dotted with minute dark-purple glands, subequal, all but the erect or slightly incurved dorsal sepal spreading; sepals 2–2.5 cm long, elliptic-lanceolate; lateral sepals wider than dorsal sepal; petals slightly shorter than sepals, somewhat falcate. Labellum obscurely 3-lobed, almost sessile, cordate, 8–10 mm long, 5.5–6.5 mm wide, purple with a whitish base, apex acute, margins entire except for minute teeth near tip; basal half erect, clasping the column, then gradually recurved; calli on lamina stalked, club-shaped, with white or yellow heads, generally in 2 well-defined rows from base to middle, thereafter less regular in shape and distribution (occasionally all reduced to a few tall basal calli); 4 basal calli club-shaped, c. 3 mm long, standing vertically in front of column, free or fused into 2 pairs. Column broadly winged on its upper part; anther with elongate point nearly 2 mm long. Flowers Sep.–Oct.

OtP. Also SA, Tas. Recorded in Victoria from near Casterton, Aireys Inlet, Anglesea and Point Lonsdale, in heathy woodland.

This taxon is a rare natural hybrid between Glossodia major and Pheladenia deformis.

Flowering is apparently promoted by fire.

Plants of similar morphology result from natural hybridisation between Glossodia major and Cyanicula caerulea.
