This is a timeline of developments in knowledge and understanding of the Australian plant genus Banksia:

18th century

• April 1770 - Sir Joseph Banks and Dr Daniel Solander collect the first specimens of Banksia at Botany Bay, New South Wales. Four species are represented: B. serrata (Saw Banksia), B. integrifolia (Coast Banksia), B. ericifolia (Heath-leaved Banksia) and B. robur (Swamp Banksia).

B. laevigata, B. lemanniana and B. incana are published, the last of these as B. sphaerocarpa var. glabrescens, but it is later promoted to species rank and renamed. In total, 58 species are listed; these are classified into two sections and four series.

Ten new species and nine new varieties are published: B. aculeata (Prickly Banksia), B. chamaephyton (Fishbone Banksia), B. conferta (Glasshouse Banksia) (and therefore also the autonym B. conferta var. conferta, now B. conferta subsp. conferta), B. conferta var. penicillata (now B. conferta subsp. penicillata), B. cuneata (Matchstick Banksia), B. ericifolia var. macrantha (now B. ericifolia subsp. macrantha), B. gardneri var. brevidentata, B. gardneri var. hiemalis, B. grossa (Coarse Banksia), B. integrifolia var. aquilonia (now B. aquilonia), B. lanata (Coomallo Banksia), B. littoralis var. seminuda (now B. seminuda), B. meisneri var. ascendens (now B. meisneri subsp. ascendens), B. micrantha, B. nutans var. cernuella, B. plagiocarpa (Dallachy's Banksia), B. saxicola (Grampians Banksia), B. scabrella (Burma Road Banksia), B. sphaerocarpa var. caesia, B. sphaerocarpa var. dolichostyla and B. telmatiaea (Swamp Fox Banksia). B. collina is demoted to B. spinulosa var. collina, and B. cunninghamii was demoted to B. spinulosa var. cunninghamii. A new infrageneric classification is proposed, and lectotypes are declared for most pre-existing Banksia taxa.
• 1984 — Barbara Rye promotes B. littoralis var. seminuda to species rank as B. seminuda.

• February 1984 - Commencement of The Banksia Atlas project, a three-year nationwide program that mobilised over 400 volunteers to make field observations of Banksia specimens.
• 1987 George publishes B. epica, B. oligantha (Wagin Banksia), B. leptophylla var. melletica and B. spinulosa var. neoanglica, all of which were discovered during The Banksia Atlas project.
• 1988 — Publication of The Banksia Atlas.

• 1996 — George promotes B. integrifolia subsp. aquilonia to species rank as B. aquilonia.
• 1999 — George publishes a monograph on the taxonomy of Banksia as part of the Flora of Australia book series. Most of Thiele and Ladiges' changes are rejected.

21st century

• 2000 — Rosser's project to paint every Banksia species concludes with the publication of the third and final volume of her monograph The Banksias.
• 2000 — B. rosserae is discovered. Accounts of its discovery differ, with some attributing Ann Pilkington, and others John Cullen.
• 2002 — Peter Olde and Neil Marriott publish B. rosserae.
• 2002 and 2005 — Austin Mast and co-authors publish cladistic analyses of genetic data, that suggest two large Banksia clades, which they name "/Cryptostomata" ("hidden stomates") and "/Phanerostomata" ("visible stomates"). Their results also strongly suggest that Banksia is polyphyletic with Dryandra.
• 2007 Austin Mast and Kevin Thiele transfer Dryandra to Banksia and publish B. subg. Spathulatae for the "/Phanerostomata", thereby redefining B. subg. Banksia as containing the "/Cryptostomata".
