Inflorescence axis with appressed antrorse hairs. Flowers on pedicels to c. 3 mm long; sepals 3.5–6 mm long, acute, connate in basal third, elongating with age, lower parts covered densely with hooked hairs; corolla (3–)6–11(–13) mm long, exceeding the sepals, glabrous, white or pale blue, tube usually only slightly longer than lobes; stamens projecting 1–7 mm from corolla-tube; style projecting 1–10 mm from corolla-tube.

A variable species, particularly in terms of flower size and shape and the degree of exsertion of the stamens from the corolla-tube. A small-flowered form with corollas 3–5 mm long has been collected in East Gippsland. A form with an exceptionally long corolla-tube (to c. 10 mm) and short lobes (to c. 3 mm) has been collected at a number of high-altitude sites in eastern Victoria.
