Marianthus mollis

Marianthus mollis is an erect, spreading, silky-hairy shrub that typically grows to a height of 50–60 cm (20–24 in), the stems usually obscured by the leaves. Its leaves are sessile, egg-shaped, 10–20 mm (0.39–0.79 in) long and 7–11 mm (0.28–0.43 in) wide and often have a reddish border. The flowers are borne singly in leaf axils on a hairy peduncle 18–25 mm (0.71–0.98 in) long. The sepals are 3–5 mm (0.12–0.20 in) long, dark blue and hairy. The five petals are purplish-blue, spatula-shaped and joined at the base, 10–18 mm (0.39–0.71 in) long with fine purple striations that darken as the flowers age. Flowering occurs in August and September.

Marianthus mollis is only known from the area near where the type collection was made, where it grows in open mallee and tall shrubland in the Esperance Plains bioregion of south-western Western Australia.
