Description

Philotheca brevifolia is a spreading shrub that grows to a height of 2 m (6 ft 7 in) with warty glands on the branchlets. The leaves are more or less cylindrical, channelled on the lower surface, sessile and 2–4 mm (0.079–0.157 in) long with warty glands. The flowers are borne singly or in groups of two to four on the ends of the branchlets, each flower on a pedicel 1–3 mm (0.039–0.118 in) long. There are five round sepals about 1 mm (0.039 in) long and five elliptical white to pink petals about 5 mm (0.20 in) long. The ten stamens are free from each other with a prominent appendage on the anther. Flowering occurs in spring and the fruit is 3 mm (0.12 in) long and beaked.[2][3]

Taxonomy

This philotheca was first formally described in 1837 by Stephan Endlicher from an unpublished description by Allan Cunningham who gave it the name Eriostemon brevifolius. Endlicher published the description in the Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel.[4] The type specimens were collected by Cunningham on "barren ground at the base of Peel's Range, interior of N.S.W." in June 1817.[5] In 1998, Wilson changed the name to Philotheca brevifolia in the journal Nuysia.[6][7]

Distribution and habitat

Philotheca brevifolia usually grows in mallee and is only known in a restricted area near Griffith in New South Wales.[2][3]
