Description

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. Lower leaves are lance to spoon-shaped, flat, 6–20 cm (2.4–7.9 in) long, 10–35 mm (0.39–1.38 in) wide on a petiole 2–10 cm (0.79–3.94 in) long, becoming sessile, wedge-shaped at the base, a pointed apex and decreasing in size near the flowers. The corolla is blue, sometimes pink or whitish, 3–6 mm (0.12–0.24 in) long, pedicel 2–5 mm (0.079–0.197 in) long, sepals elliptic-shaped to almost triangular, rounded or blunt and enlarging as the fruit ages. 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]
