Description

Goodenis dimorpha is an erect, glabrous herb that typically grows to a height of 50 cm (20 in) and has adventitious roots. The leaves are mostly at the base of the plant, linear to egg-shaped with the narrower end towards the base, 10–50 mm (0.39–1.97 in) long and 2–11 mm (0.079–0.433 in) wide, sometimes with a few small teeth on the edges. The flowers are arranged in thyrse-like panicles up to 400 mm (16 in) long on a peduncle up to 140 mm (5.5 in) long with linear bracts at the base, each flower on a pedicel about 3 mm (0.12 in) long. The sepals are 2–6 mm (0.079–0.236 in) long, the corolla yellow, 12–15 mm (0.47–0.59 in) long. The lower lobes of the corolla are about 6 mm (0.24 in) long with wings about 3 mm (0.12 in) wide. The fruit is a narrow cylindrical to oval capsule 8–10 mm (0.31–0.39 in) long. [2] [3] [4]

Taxonomy

Goodenia dimorpha was first formally described in 1904 by Joseph Maiden and Ernst Betche in the Proceedings of the Linnean Society of New South Wales . In 1990, Roger Charles Carolin selected the lectotype as material collected by Betche near Woodford in 1899. [5] [6] [7]

In the same journal, Maiden and Betche described two varieties, and the names are accepted by the Australian Plant Census:

Distribution and habitat

This goodenia in swampy ground on sandstone plateaus. Variety angustifolia occurs from the Gosford district to Waterfall and var. dimorpha mainly near Blackheath in the Blue Mountains. [9] [10] [12] [13]
