Some versions of the system are available online. The Bioinformatics Working Group Center for the Study of Digital Libraries at Texas A&M University lists the March 1999 version[9] (and other classification systems).[10] James Reveal's course lecture notes (1999) also gives an account of the Thorne system at that time, with an extensive listing of synonyms, both nomenclatural and taxonomic, for each name in the system[11] together with several other classification systems.[12]
For a discussion of the varioussuffixes used forsuperorders (-floraevs.-anae), see Brummitt 1992,[13] and Thorne 1992.[5] In this latter paper, Thorne sets out his reasons for abandoning-florae for-anae, following contemporary practice.

This is a selected list of the more influential systems. There are many other systems, for instance a review of earlier systems, published byLindley in his 1853 edition, andDahlgren (1982). Examples include the works ofScopoli,Ventenat,Batsch andGrisebach.
