An annual (or possibly rarely a short-livedperennial) herb to c. 25 cm high, single-stemmed or occasionally with several stemsarising from base. Stems erect or ascending, glabrous, sometimes producingadventitious roots from lower nodes. Leaves linear 5–21 mm long, 0.4–3 mm wide, glabrous. Flowers bisexual, each initiallydeveloping in the axil of one leaf of a sub-opposite pair of distal leaves, so that a flower appears to be borne at every second node, pedicels 16–55 mm long, glabrous. Calyx lobes 1.5–2.5 mm long.Corolla weakly 2-lipped, 10–14 mm long; upper lip two-lobed, violet-blue; lower lipthree-lobed, the lobes basally fused for c. 2–3.5 mm above the sinus between the twolips, the fused part with a prominent central yellow zone and 3 deep purple, ?basallyfused broad bands, deep purple bands extending into the tube on the ventral side andcovered with dense club-shaped hairs; central lobe violet-blue distally, whiteproximally; lateral lobes mostly violet-blue but white proximally on the half adjacent tothe central lobe; tube 5–7 mm long Seeds subcylindrical to ovoid, 0.38–0.5 mm long, mid to dark brown.


A short-lived, ephemeral semi-arid species that occurs nearCuttabri, south west of Wee Waa in north western NSW. It is currentlyknown from three sites that are no more than 5.5 km apart and located on private landin sedge-dominated wetlands occupying shallow basins on the Namoi River floodplain

Habitat and ecology

  • Occurs in moist situations, ephemeral wetlands.
  • Probably germinates opportunistically (with inundation).
  • Flowering is reported from October, probably into summer, dependent on timing and extent of inundation.
