On the Proteaceae: the evolution and classification of a southern family
Encyclopedia
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 L. A. S. Johnson and Barbara Briggs
, it appeared in Volume 70 of Botanical Journal of the Linnean Society
in 1975.
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".
Evolution
Evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organisation, including species, individual organisms and molecules such as DNA and proteins.Life on Earth...
, biogeography
Biogeography
Biogeography is the study of the distribution of species , organisms, and ecosystems in space and through geological time. Organisms and biological communities vary in a highly regular fashion along geographic gradients of latitude, elevation, isolation and habitat area...
and taxonomy
Taxonomy
Taxonomy is the science of identifying and naming species, and arranging them into a classification. The field of taxonomy, sometimes referred to as "biological taxonomy", revolves around the description and use of taxonomic units, known as taxa...

Flowering plant
The flowering plants , also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants. Angiosperms are seed-producing plants like the gymnosperms and can be distinguished from the gymnosperms by a series of synapomorphies...

Proteaceae
Proteaceae is a family of flowering plants distributed in the Southern Hemisphere. The family comprises about 80 genera with about 1600 species. Together with the Platanaceae and Nelumbonaceae they make up the order Proteales. Well known genera include Protea, Banksia, Embothrium, Grevillea,...
