Scientific name: Diuris eborensis

Gazetted date: 02 Oct 2015
Profile last updated: 24 May 2018


Terrestrial orchid with 3-6 linear, grass-like leaves, often forming small, clonal clusters of plants so may appear to have many more leaves. Inflorescence arises from the centre of the leaf cluster, erect, to 40 cm tall (usually much less) bearing 1 to 6 flowers which may be creamy to yellow, usually marked with purple or red lines and suffusions, or heavily marked with these darker colours. Flowers tend to be outward facing to nodding, and are subtended by relatively large bracts. The labellum is much larger than the other petals and as large as or larger than the dorsal sepal, with a large and prominent channeled callus forming two prominent ridges on the labellum, a third ridge nearer the apex between these, and a scalloped margin to the labellum mid-lobe.

No clear dormant period is observed, although most active growth occurs in autumn and spring, with flowering in later half of spring into very early summer.


Found mainly in damp grassland and woodland sites or in areas of sedge and swampy sites. Main locations are higher altitude sites in the eastern New England Plateau, with known locations in the Ebor, Yarrowitch and Backwater areas.

Typically in brown clay loam soil over an igneous substrate (basalt most commonly in the sites visited, but not always), but the soil may have large amounts of organic matter.
