Recorded distribution
Recorded distribution

Plant

In dense colonies; leaf shortly stalked.

Flowers

Large, 10-20 mm long, dorsal sepal almost transparent, streaked red veins ridged; labellum ragged, like a piece of meat, often with a long drip tip with a small bead in the throat.

Flowering

August - October.

Habitat

Calcareous siltstone, mudstone and limestone and fertile soils; streamsides, damp areas.

Conservation

Common, often locally abundant.

Notes

Like C. hatchii but appears to be distinguished by the bead in the throat and the deep red labellum colour and rough texture. There are a number of similar plants that lack the bead in the throat but are often identified with this. Their taxonomic status is uncertain

Key features

Large flower, dark labellum colour, ridged dorsal sepal.
