On the Proteaceae
1975 paper by Lawrie Johnson and Barbara Briggs
On the Proteaceae: The Evolution and Classification of a Southern Family is a highly influential monograph on the evolution, biogeography and taxonomy of the flowering plant family Proteaceae. Authored by Lawrie Johnson and Barbara Briggs, it appeared in Volume 70 of Botanical Journal of the Linnean Society in 1975. Johnson and Briggs had presented what would become the paper at a meeting of the Linnaean Society on 6 December 1973 amid celebrations of 200 years since the birth of Robert Brown.
One of its most important and long-lasting contributions was the establishment for a suprageneric classification of the Proteaceae, which was accepted with only minor modifications until 2006, when Peter H. Weston and Nigel P. Barker presented a new arrangement based primarily upon molecular data. According to Weston and Barker, "Johnson and Briggs' classification has served as the systematic framework for a generation of researchers".
This brief starts where responsible research should: with the source description of “On the Proteaceae” as 1975 paper by Lawrie Johnson and Barbara Briggs. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 1975 paper by Lawrie Johnson and Barbara Briggs. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 7, 2025. The linked authority identifier is Q7091459. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1975, 1973 and 2006.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
