PFR: Taxonomy

This informal system of vascular plant classification is based on C.J. Cleal 1993 ("The Fossil Record 2", Chapman & Hall, London) for pteridophytes and gymnosperms, and on R.K. Brummitt 1992 ("Vascular Plant Families and Genera" Royal Botanic Gardens, 804pp) for angiosperms.

"form-genera" are those taxa that cannot be assigned to a family or a taxon of higher rank.

"Clealopsida" are informal names for groups referred to in Cleal 1993.
