Abstract
The synopsis of my classification of the Angiospermae that was published in Aliso (Thorne, 1968) has been much modified in recent years. Increased knowledge about many of the families has resulted in a realignment of some of them and reorganization or deletion of some of the higher categories. I have published elsewhere some explanation of my classificatory modus operandi (Thorne, 1958, 1963, 1974c) and some elucidation of certain of my major groupings, such as the Araliaceae, Annoniflorae, Urti-cales, Juglandineae, Hamamelidales, Sapindineae, and Pittosporales (Thorne 1973, 1974a,b,c, 1975). I have other manuscripts near completion and have been preparing an illustrated book with full exposition of my classification of the angiosperms. Nonetheless, it seems desirable at this time to present an updated version of my synopsis of the Angiospermae with at least a brief review of my philosophy of classification, my interpretation of the probable origins of the angiosperms and their most primitive characteristics, and some elucidation of realignments that deviate considerably from other recent classifications.
