Taxonomy.
This philotheca was first formally described in 1844 by Joseph Paxton who gave it the name "Eriostemon scaber" and published the description in "Paxton's Magazine of Botany" from a specimen "in the nursery of Messrs. Henderson, of Pine Apple Place, who received it from the gardens of Baron Hugel, at Vienna, about twelve months back". In 1970, Paul G. Wilson described two subspecies of "Eriostemon scaber" in the journal "Nuytsia":
In 1998, Wilson changed the species name to "Philotheca scabra" and the subspecies to "P. scabra" subsp. "latifolia" and "P. scabra" subsp. "scabra" respectively, in a later edition of the same journal: The names of the subspecies are accepted by the Australian Plant Census:
Distribution and habitat.
"Philotheca scabra" grows in heath and forest on the coast and nearby ranges of New South Wales between Sydney and the Nerriga and Nowra districts. Subspecies "scaber" occurs in the northern part of the species' distribution and subsp. "latifolius" near Nerriga and Nowra.
