Guichenotia macrantha, commonly known as large-flowered guichenotia, is a species of flowering plant in the family Malvaceae. It is a shrub with grey-green leaves, mauve flowers and is endemic to Western Australia.
Description
Guichenotia macrantha is an open, upright, or sometimes a straggling small or tall shrub to 1–2 m (3 ft 3 in – 6 ft 7 in) high, 1.5–2 m (4 ft 11 in – 6 ft 7 in) wide with new growth covered in star-shaped hairs. The leaves are linear to oblong shaped, upper surface grey-green, 20–95 mm (0.79–3.74 in) long, 1.5–2 mm (0.059–0.079 in) wide, margins rolled under, lower surface yellowish-green, wrinkled, thickly hairy, rounded apex on a petiole 2–3 mm (0.079–0.118 in) long. The calyx lobes are mauve, pink-purple, sometimes white, each lobe with three distinct ribs, 1.5–2.5 cm (0.59–0.98 in) in diameter, divided to halfway, petals deep red, small, pedicel 8–15 mm (0.31–0.59 in) long and peduncles 18–50 mm (0.71–1.97 in) long. The bracts are leaf-like, oval-shaped, 8–12 mm (0.31–0.47 in) long, 1–2 mm (0.039–0.079 in) wide and borne at the base of each pedicel. Flowering occurs from May to September and the fruit is a woody, elliptic-shaped capsule.
