Description

Goodenia psammophila is a prostrate or erect annual herb that typically grows to a height of 50 cm (20 in) with multiple stems. The leaves at the base of the plant are narrow lance-shaped to egg-shaped leaves with the narrower end towards the base, 10–91 mm (0.39–3.58 in) long and 3–21 mm (0.12–0.83 in) wide, sometimes with toothed or pinnatisect edges. The stem leaves are linear, decreasing is size towards the tips of the stems. The flowers are arranged in leafy racemes, each flower on a pedicel 11–37 mm (0.43–1.46 in) long. The sepals are narrow elliptic to linear, 1–2.1 mm (0.039–0.083 in) long and the corolla yellow with brownish or whitish lobes and 6.5–9.2 mm (0.26–0.36 in) long. The lower lobes of the corolla are about 3 mm (0.12 in) long with wings about 1.5 mm (0.059 in) wide. Flowering mainly occurs between December and February and the fruit is an elliptic capsule 3.5–5 mm (0.14–0.20 in) long. [2] [3]

Taxonomy and naming

Goodenia psammophila was first formally described in 2001 by Leigh William Sage and Matthew David Barrett in the journal Nuytsia from material collected by Barrett east of Mount Agnes in the West Kimberley region in 1998. [2] [4] The specific epithet (psammophila) means "sand-loving", referring to the usual habitat of this species. [2]

In the same journal, Sage and Barrett described two subspecies and the names are accepted by the Australian Plant Census:

The subspecies name (hiddinsiana) honours Major Les Hiddins. [2]

Distribution and habitat

This goodenia grows in sandy soil on flats, ridges and near creeks in the Northern Kimberley biogeographic region in Western Australia. [2] [3]

Conservation status

Goddenia psammophila subsp. psammophila is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife [3] meaning that it is poorly known and known from only a few locations but is not under imminent threat, but subspecies hiddinsiana is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife [3] meaning that it is poorly known and from only one or a few locations.
