Bracteate donkey orchid
Taxonomy & Nomenclature
Synonym/s: Diuris praecox D.L.Jones, 1991:60(?) (see Silcock et al., 2019:SM:1)
Not a good species according to (Silcock et al., 2019:SM:16), who also note that "Diuris praecox may be a synonym and there is uncertainty over the identification of recent collections" (Silcock et al., 2019:SM:1).
Conservation Status
Last record: pre-1889 (Silcock et al., 2019:SM:1)
Rediscovered in 1998 (Silcock et al., 2019:SM:16)
Erroneously thought to be extinct after specimens of D. bracteata were misidentified as D. platichila.
Distribution
near Gladesville, Parramatta River, New South Wales, Australia
