Description

Homoranthus biflorus is an erect shrub which grows to a height of 1.2 metres (4 ft). It has glabrous, linear, more or less cylinder-shaped leaves with a pointed tip. The leaf blade is linear in side view, less than 1 millimetre (0.04 in) thick. Flowers appear singly or in pairs and are red, yellow, or greenish-yellow with petals about 2 millimetres (0.08 in) long surrounding the base of a style which is 6–10 millimetres (0.2–0.4 in) long. Flowers and fruits sporadically throughout the year , although primarily between October and January.[2][3]

Taxonomy and naming

Homoranthus biflorus was first formally described in 1991 by Lyndley Craven and S.R.Jones and the description was published in Australian Systematic Botany.[4]

Distribution and habitat

This homoranthus grows in heath and woodland on volcanic ridges on the Northern Tablelands of New South Wales.[2]

Conservation status

Locally common though restricted in distribution, Barbara Briggs and John Leigh (1996) gave this species a conservation code of 2RCat;. However 2RC is more appropriate given that some plants near Pindarri Dam are unreserved.[5]
