Description

Goodenia nuda is an erect to ascending herb that typically grows to a height of up to 50 cm (20 in). It has elliptic to lance-shaped leaves with the narrower end towards the base, at the base of the plant, 30–60 mm (1.2–2.4 in) long and 8–20 mm (0.31–0.79 in) wide, sometimes with a few narrow teeth on the edges. The flowers are arranged in racemes up to 250 mm (9.8 in) long, with leaf-like bracts, each flower on a pedicel 20–50 mm (0.79–1.97 in) long. The sepals are narrow-elliptic to lance-shaped, 3–3.5 mm (0.12–0.14 in) long, the petals yellow, 14–16 mm (0.55–0.63 in) long. The lower lobes of the corolla are 6–7 mm (0.24–0.28 in) long with wings about 2 mm (0.079 in) wide. Flowering mainly occurs from April to August and the fruit is an oval to spherical capsule 6–7 mm (0.24–0.28 in) in diameter.[2][3]

Taxonomy and naming

Goodenia muelleriana was first formally described in 1905 by Ernst Georg Pritzel in the journal Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie from a specimen collected near Roebourne.[4][5] The original specimens have been lost, but in 1990 Roger Charles Carolin selected the specimens he collected near Onslow as the neotype.[6] The specific epithet (nuda) means "naked" or "bare", referring to the sparsely-leaved stems.[7]

Distribution

This goodenia grows in the Gascoyne, Little Sandy Desert and Pilbara biogeographic regions in the north-west of Western Australia.[2][3]

Conservation status

Goodenia muelleriana is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife,[3] meaning that is rare or near threatened.[8]
