Homoranthus floydii is easily distinguished from all other species of Homoranthus by its erect habit, shiny leaves that appear more pointed near the stem and rounded at the tip, long gaps between leaf nodes and particularly long flower stems. Flowering occurs from August to November and fruits mature from September to December.
This species is endemic to the Glenreagh district of north-eastern New South Wales, where it grows on shallow rocky soils derived from sandstone in shrubby woodland.
