Cynoglossum australe commonly known as the Australian hound's tongue,[2] is a flowering plant in the family Boraginaceae.

Cynoglossum australe is an upright herb 30–75 cm (12–30 in) high, occasionally taller, with stems covered in stiff, backward or downward spreading hairs.

Flowering occurs mostly in spring and summer and the fruit is a flattened, oval to globe-shaped schizocarp, light brown to yellowish-brown, 2.5–3.5 mm (0.098–0.138 in) long and covered in spines of varying length on the lower surface.

[2][3][4] Cynoglossum australe was first formally described in 1810 by Robert Brown and the description was published in Prodromus florae Novae Hollandiae.

[7] Australian hound's tongue is a widespread species found growing in a diverse range of locations including woodland, grassland, sand dunes and montane forest in Queensland, Victoria, New South Wales, Western Australia and the Australian Capital Territory.
