Diuris pedunculata
species of plant
Diuris pedunculata, commonly known as the small snake orchid, is a species of orchid which is endemic to New South Wales. It usually has two leaves at its base and one or two yellow and orange flowers with purple markings. It originally occurred in scattered populations between Tenterfield and the Hawkesbury River but because of habitat loss is now only known from the New England Tableland.
Description
Diuris pedunculata is a tuberous, perennial herb with two erect, linear to thread-like leaves 40–120 mm (2–5 in) long and 1–2 mm (0.04–0.08 in) wide. One or two pale yellow flowers with an orange labellum, 15–20 mm (0.6–0.8 in) wide are borne on a flowering stem 60–180 mm (2–7 in) tall. The dorsal sepal is narrow egg-shaped, angled upwards, 7–10 mm (0.3–0.4 in) long and 5–6 mm (0.20–0.24 in) wide. The lateral sepals are lance-shaped with the narrower end towards the base, 15–20 mm (0.6–0.8 in) long, about 3 mm (0.1 in) wide and angled downwards. The petals are narrow elliptic, 9–14 mm (0.4–0.6 in) long, 4–5.5 mm (0.16–0.22 in) wide, spread apart from each other and droop downwards on a dark coloured stalk 2–3 mm (0.08–0.1 in) long. The labellum is 14–16 mm (0.55–0.63 in) long and has three lobes. The centre lobe is broadly egg-shaped, 7–10 mm (0.3–0.4 in) wide and the side lobes are triangular, about 2 mm (0.08 in) long and 1 mm (0.04 in) wide.
The public source identifies “Diuris pedunculata” as species of plant. This brief keeps that definition visible, then builds a research path around Diuris, pedunculata and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Diuris pedunculata”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 13, 2026. The linked authority identifier is Q10267411. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
