Description

edit

Goodenia porphyrea is a low-lying to prostrate herb with stems up to 50 cm (20 in) long with scattered, stiff, white hairs on the foliage. At the base of the plants there are egg-shaped leaves with the narrower end towards the base, but the stem-leaves are narrow oblong to lance-shaped 250–110 mm (9.8–4.3 in) long and 2–5 mm (0.079–0.197 in) wide with toothed edges and two large teeth at the base. The flowers are arranged in racemes up to 400 mm (16 in) long, with leaf-like bracts, each flower on a pedicel up to 10 mm (0.39 in) long. The sepals are narrow oblong to lance-shaped, 4–5 mm (0.16–0.20 in) long, the petals purplish to apricot or brownish, 8–10 mm (0.31–0.39 in) long. The lower lobes of the corolla are 2–3 mm (0.079–0.118 in) long with wings about 1 mm (0.039 in) wide. Flowering mostly occurs from March to April and the fruit is a more or less spherical capsule 5–6 mm (0.20–0.24 in) in diameter.[2][3]

Taxonomy and naming

edit

This species was first formally described in 1979 by Roger Charles Carolin in the journal Brunonia and given the name Calogyne porphyrea from specimens collected in 1966.[4] In 1990, Carolin changed the name to Goodenia porphyrea in the journal Telopea.[5][6] The specific epithet (porphyrea) means "purple or purplish-red".[7]

Distribution and habitat
