Leaves not joined at nodes, lamina c. ovate, usually broadly so, mostly 1–5 mm long, 1–3 mm wide, apex acute to obtuse, base more or less rounded, margins entire; petioles to c. 1 mm long. Flowers solitary in axils; pedicels 1–10 mm long. Calyx 2.5–5 mm long, teeth almost equal, c. 0.5 mm long; corolla 2-lipped, with the limb blue, purple or pink, tube 5–10 mm long, white or yellow sometimes with red spots, lower lip c. 4 mm long with a prominent yellow raised palate at the base, closing the mouth. Capsule globose to ellipsoid, c. 5 mm long. Flowers Sep.–Apr.

CVU, DunT, EGL, EGU, GipP, Glep, Gold, MuM, MSB, OtP, VRiv, VVP, WaP, WPro, Wim. Also WA, SA, Qld, NSW, Tas. Widespread in swampy sites, open margins of lakes, watercourses, or in temporarily wet areas, often in brackish to quite saline sites (e.g. margins of coastal and inland saltmarshes).

There is considerable variation in the robustness and orientation of the stems, and the size of the leaves and flowers. This variation seems to be more environmentally than genetically influenced.
