Up to three yellow flowers, usually with dark red markings, {{cvt|10–15|mm}} long and {{cvt|9–11|mm}} wide are borne on a flowering stem {{cvt|100-200|mm}} tall. The dorsal sepal is narrowly egg-shaped to narrowly elliptic, {{cvt|7–10|mm}} long and {{cvt|3.5–5.5|mm}} wide. The lateral sepals are parallel or crossed near the tip, {{cvt|8–13|mm}} long, {{cvt|1–3|mm}} wide. The petals are paddle-shaped, the blade elliptic to egg-shaped or more or less round, {{cvt|6–9|mm}} long and {{cvt|4–8|mm}} wide on a reddish-brown stalk {{cvt|3–5|mm}} long.

Taxonomy and naming
Diuris segregata was first formally described in 2013 by David Jones and Christopher J. French in Australian Orchid Review, from a specimen collected by French near Yallabatharra in 2004.{{cite web|title=Diuris segregata|url= https://id.biodiversity.org.au/instance/apni/761664|publisher=APNI|accessdate=14 August 2023}} The specific epithet (segregata) means "separate", or "set apart", referring to its differences from D. septentrionalis, that grows in a similar area.
Distribution and habitat
Northampton bee orchid grows in winter-wet areas, near the edges of temporary lakes and around rocks between Eneabba and Kalbarri in the Avon Wheatbelt, Geraldton Sandplains and Swan Coastal Plain bioregions of south-western Western Australia.
Conservation status
Diuris segragata is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
