white goodenia

Goodenia scapigera is an erect, perennial herb or shrub that typically grows to a height of 0.3–1.5 m (1 ft 0 in – 4 ft 11 in) and is glabrous. The leaves are linear to narrow egg-shaped with the narrower end towards the base, more or less clustered at the ends of the stems, 40–60 mm (1.6–2.4 in) long and 2–10 mm (0.079–0.394 in) wide, sometimes with toothed edges. The flowers are arranged in thyrses up to 200 mm (7.9 in) long, with linear bracts about 5 mm (0.20 in) long and linear bracteoles about 2 mm (0.079 in) long. Each flower is on a pedicel 1–3 mm (0.039–0.118 in) long with linear to triangular sepals 7–8 mm (0.28–0.31 in) long. The petals are white with purplish spots near the base, 8–18 mm (0.31–0.71 in) long, the lower lobes of the corolla 7–11 mm (0.28–0.43 in) long with wings about 1 mm (0.039 in) wide. Flowering mainly occurs from September to January and the fruit is an oval to elliptical capsule 5–7 mm (0.20–0.28 in) long.

This goodenia usually grows in sandy soil in woodland or heath and is widespread in the Avon Wheatbelt, Coolgardie, Esperance Plains, Jarrah Forest, Mallee and Swan Coastal Plain biogeographic regions in the south west of Western Australia. Subspecies graniticola has a more restricted distribution, growing in heath in granitic soil near Peak Charles National Park.
