Reveal system

A 20th-century system of plant taxonomy, the Reveal system of plant classification was drawn up by the American botanist James Reveal (1941–2015). The system was published online in 1997 in ten parts as lecture notes comparing the major systems in use at that time. Subsequently, Reveal became an author with the consensus Angiosperm Phylogeny Group (APG) on the APG II 2003 and APG III 2009 processes. Although this largely supplanted the earlier and competing systems, he collaborated with Robert Thorne on his system (2007), and subsequently continued to develop his own system.
