A modern system of plant taxonomy, the Thorne system (1992) of plant classification was drawn up by the botanist Robert F. Thorne (1920- ). He replaced it in 2000 with a new system. The system is available online at two sites. Firstly, at the Center for the Study of Digital Libraries Texas A&M.〔(Robert F. Thorne. 1992. Classification and Geography of Flowering Plants. Botanical Review 58: 225-348 as updated December, 1992 and March, 1999. )〕 Secondly in the 1999 lecture notes by J.L. Reveal, at that time a professor at the Norton Brown Herbarium, University of Maryland 〔(JL Reveal. Thorne System of Angiosperm Classification 1 )〕〔(JL Reveal. Thorne System of Angiosperm Classification 2 )〕〔(JL Reveal. Thorne System of Angiosperm Classification 3 )〕 with an extensive listing of synonyms, both nomenclatural and taxonomic, for each name in the system). The Thorne system (1992) counts 440 families and 69 orders. Earlier versions used the -florae suffix for superorder.〔Brummitt, R.K., 1992, Vascular Plant Families and Genera, pp. 770-76.
