Description

edit

Philotheca nutans is a densely-branched shrub that grows to a height of 30–90 cm (12–35 in) with glandular-warty branchlets. The leaves are cylindrical to club-shaped, about 11 mm (0.43 in) long and glandular-warty on the lower surface. The flowers are pendent and borne singly in leaf axils, each flower on a thin pedicel about 8 mm (0.31 in) long. There are five broadly egg-shaped sepals about 2.5 mm (0.098 in) long and five broadly egg-shaped, pale yellow to pale red petals 7–10 mm (0.28–0.39 in). The ten stamens are densely woolly-hairy. Flowering occurs from July to September.[2][3][4]

Taxonomy and naming

edit

This philotheca was first formally described in 1970 by Paul Wilson who gave it the name Eriostemon nutans and published the description in the journal Nuytsia from specimens collected by Charles Gardner in 1953.[3][5] In 1998, Wilson changed the name to Philotheca nutans in the same journal.[6][7]

Distribution and habitat

edit

Philotheca nutans grows in woodland near the Wubin-Paynes Find road in the south-west of Western Australia.[2]

Conservation status

edit

Philotheca nutans is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife,[4] meaning that it is known from only one or a few locations which are potentially at risk.[8]
