Taxonomy

This grevillea was first formally described in 1986 by Donald McGillivray who gave it the name ''Grevillea pilosa'' subsp. dissecta'' in his book ''New names in Grevillea (Proteaceae). In 1993 Peter Olde and Neil Marriott raised the subspecies to species status as ''Grevillea dissecta'', but the name was illegitimate because it had already been used for a fossil species. In 2014, Ian Mark Turner changed the name to ''Grevillea neodissecta'' in ''Annales Botanici Fennici''. The
