Synonymy: Not Applicable

Common name: Sweet hounds tongue, sweet forget-me-not.

Perennials to 40 cm high, with one to few erect stems from the basal rosette, with a tap root, covered with spreading to appressed hairs being usually a mixture of short fine ones and longer ones with a broad base; leaves densely clustered, oblanceolate, subpetiolate but with a broadened sheath in the basal rosette becoming widely spaced, lanceolate and sessile below the inflorescence, 2-15 x 0.7-1.8 cm, pointed, often with undulate margins.

Inflorescence terminal, with 1 to a few monochasia being once or twice dichotomously branched, with pedicellate flowers subtended by often leaf-like bracts; sepals connate to half their length, 2-3 mm long or to 4 mm when fruiting, with lobes triangular, bluntly acute to rounded, covered with forward-directed appressed hairs; corolla funnel-shaped, blue, glabrous except for papillose 2-lobed saccate protrusions in the throat, 4-4.5 mm long; lobes broadly oblong-ovate, c. 2 mm long, with a rounded apex; stamens inserted just above the middle of the corolla tube, with anthers almost sessile, narrowly ovoid to ellipsoid, c. 1 mm long, constricted towards the apex but without an appendage; ovary 4-lobed, with the c. 1.5 mm long style inserted near the base, slightly broadened towards the base and with a capitate terminal stigma.

Mericarps almost globular and without a winged rim, densely covered on the upper surface with coarse spines with barbed apices, pale-brown.

Biology: It is remarkable how few flowers of this species on South Australian specimens set fruit and yet it does not seem to be a rare plant. This is even more remarkable when one compares it with the prolific C australe.
