Pedicels 10–25 mm long, elongating in fruit; sepals ovate, 2–2.5 mm long, acute; corolla 2–4 mm long, glabrous except for papillose 2-lobed scales in throat, white, pale blue or pale mauve, tube more or less as long as the obtuse lobes; anthers to c. 0.3 mm long.

Apparent intergeneric hybrids with Cynoglossum (possibly C. suaveolens) have been collected near Melbourne and Warragul. These have the petiolate rosette leaves, sessile cauline leaves and indumentum of Cynoglossum but the leaf shape and predominantly single-flowered inflorescences of Austrocynoglossum. The specimens do not have fruit.
