The flowers are red, sepals red, 3–4 mm (0.12–0.16 in) long and the styles black and 22–30 mm (0.87–1.18 in) long. Flowering occurs sporadically throughout the year and the fruit is a one-seeded nut.

Taxonomy and naming

Homoranthus zeteticorum was first formally described in 1991 by Lyndley Craven and Sandra Raelene Jones and the description was published in Australian Systematic Botany . [3] [4] The specific epithet (zeteticorum) is from the Greek zetetikos, meaning "disposed to research", latinised and given the genitive plural form, meaning "in honour of persons who, for their enjoyment, explore natural vegetation". [5] [6]

Distribution and habitat

This homoranthus grows in shrubby woodland and heath on shallow, sandy soils derived from sandstone. It is only known from the Salvator Rosa section of Carnarvon National Park where it grows on Homoranthus Hill. [2] [7] [8]

Homoranthus zeteticorum is considered a rare species with a restricted distribution. ROTAP conservation code 2RC-, Briggs and Leigh (1996). [2]
