Appearance
"Isopogon ceratophyllus" is a prickly shrub, growing to 15–100 cm tall and to 120 cm across. The oval to round flower heads, known as inflorescences, appear between July and January, and are around 3 cm in diameter.
Distribution
The species ranges from south-western Victoria into the south-eastern corner of South Australia and in the Furneaux Group of Bass Strait islands, principally Flinders, Cape Barren and Clarke Islands. A King Island record has not been reconfirmed and is unlikely. It is the only "Isopogon" species found in South Australia. It grows on sandy soils in open eucalyptus forest or woodland. or heathland.

Fieldwork in the Brisbane Ranges in 1994 showed that "I. ceratophyllus", which had been common in areas before dieback and had vanished along with other sensitive species, had yet to return after 30 years. This was despite other sensitive species, such as grasstree, smooth parrot-pea, erect guinea flower and prickly broom heath, eventually regenerating around 10 years post-infection. All Tasmanian populations are at risk of eradication by "P. cinnamomi". Plants are perishing at Wingaroo Nature Reserve on Flinders Island from exposure to the pathogen.References:
