Description

edit

Goodenia argillacea is a herb that typically grows to a height of up to 70 cm (28 in), with an erect main stem and weak, low-lying branches. The leaves are arranged along the stems and are oblong to linear, 20–45 mm (0.79–1.77 in) long and 2.5–6 mm (0.098–0.236 in) wide. The flowers are arranged in racemes up to 600 mm (24 in) long on pedicels 2.5–4 mm (0.098–0.157 in) long. The sepals are lance-shaped, about 2.5 mm (0.098 in) long, the corolla brownish-yellow and 10–12 mm (0.39–0.47 in) long. The lower lobes of the corolla are about 2.5 mm (0.098 in) long with wings about 1 mm (0.039 in) wide. Flowering mainly occurs around May and the fruit is an oval capsule 3–3.5 mm (0.12–0.14 in) long.[2][3]
