This species was first formally described in 1863 by George Bentham who gave it the name Marianthus laxiflorus in Flora Australiensis.[2] [3] In 1972, Eleanor Marion Bennett transferred the species to Billardiera as B. laxiflora.[4] The specific epithet (laxiflora) means "loose- or open-flowered".[5]
Billardiera laxiflora grows in woodland and forest on laterite in the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren bioregions of far south-western Western Australia.
