Bessey system

From Wikipedia, the free encyclopedia

A system of plant taxonomy, the Bessey system was published in

Charles E. Bessey (1915). "The phylogenetic taxonomy of flowering plants". Annals of the Missouri Botanical Garden 2: 109–164. doi:10.2307/2990030.  available online at Botanicus.org (PDF). Missouri Botanical Garden. Retrieved on 2007-08-16.

Bessey considered Spermatophyta as having had polyphyletic origin, being composed by three different phyla, of the which he treated only of Anthophyta (syn.: Angiosperms).

With some modifications, most modern classifications - for example, those of Cronquist (1981, 1983, 1988), Takhtajan (1969, 1980, 1983, 1991), Stebbins (1974), R. Dahlgren (1975, 1980, 1983; R. Dahlgren et al. 1981; R. Dahlgren and Rasmussen 1983; R. Dahlgren and Bremer 1985; G. Dahlgren 1989), and Thorne (1976, 1981, 1983, 1992) - follow the Bessey tradition. [1]
