Thorne system

A system of plant taxonomy, the Thorne system of plant classification was devised by the American botanist Robert F. Thorne (1920–2015) in 1968,{{sfn|Thorne|1968}} and he continued to issue revisions over many years (1968–2007).{{sfn|Thorne|1968}}{{sfn|Thorne|1976}}{{sfn|Thorne|1977}}{{sfn|Thorne|1983}}{{sfn|Thorne|1992a}}{{sfn|Thorne|1992b}}{{sfn|Reveal|1999a}}{{sfn|Thorne|Reveal|2007}}

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[http://www.csdl.tamu.edu/FLORA/newgate/thor1ang.htm Robert F. Thorne. 1992. Classification and Geography of Flowering Plants. Botanical Review 58: 225-348 as updated December, 1992 and March, 1999.] Source for March 1999 in {{harvtxt|Reveal|1999a}} (and other classification systems).[http://botany.csdl.tamu.edu/FLORA/newgate/cronang.htm Texas A&M Flowering Plant Gateway] 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{{sfn|Reveal|1999b}} together with several other classification systems.{{sfn|Reveal|1999c}}

For a discussion of the various suffixes used for superorders (-florae vs. -anae), see Brummitt 1992,{{sfn|Brummitt|1992|loc=pp. 770–776}} and Thorne 1992.{{sfn|Thorne|1992a}} In this latter paper, Thorne sets out his reasons for abandoning -florae for -anae, following contemporary practice.

1968 System

Superorders

1992 System

The 1992 system lists 69 orders and 440 families

= Summary =

= Magnoliidae =

= Liliidae =

2007 System

The 2007 system lists 12 subclasses, 35 superorders, 87 orders, 40 suborders, and 472 families. It uses the suffixes given in the following example.

Class Magnoliopsida ("Angiospermae") - 12 subclasses

  • Subclass Magnoliidae
  • Superorder: Magnolianae
  • Order: Magnoliales
  • SubOrder: Magnoliineae
  • Family: Magnoliaceae
  • SubFamily: Magnolioideae
  • Tribe: Magnolieae

;Subclasses (12)

Note: Monocotyledons are represented here by 3 separate subclasses 3–5{{sfn|Singh|2019|loc=p. 260}}
