Taxonomy
Conospermum caeruleum was first formally described in 1810 by Robert Brown and the description was published in Transactions of the Linnean Society of London from a specimen collected near "King George's Sound, west coast of New Holland".[4][5] The specific epithet (caeruleum) is a Latin word meaning "sky-blue".[6]
Six subspecies are recognised by the Australian Plant Census as at November 2020:
- Conospermum caeruleum R.Br. subsp. caeruleum[7]
- Conospermum caeruleum subsp. contortum E.M.Benn.[8]
- Conospermum caeruleum subsp. debile (Kippist ex Meisn.) E.M.Benn.[9]
- Conospermum caeruleum subsp. marginatum (Meisn.) E.M.Benn.[10]
- Conospermum caeruleum subsp. oblanceolatum E.M.Benn.[11]
- Conospermum caeruleum subsp. spathulatum Benth. E.M.Benn.[12]
