Bessey System

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 (Missouri Botanical Garden Press) 2 (1/2): 109–164. doi:10.2307/2990030. JSTOR 2990030. available online at "Botanicus.org" (PDF). Missouri Botanical Garden. http://www.botanicus.org/item/31753999990002. Retrieved 2007-08-16.

Bessey considered Spermatophyta as having a polyphyletic origin, being composed by three different phyla, of which he only treated 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.

Famous quotes containing the word system:

    Columbus stood in his age as the pioneer of progress and enlightenment. The system of universal education is in our age the most prominent and salutary feature of the spirit of enlightenment, and it is peculiarly appropriate that the schools be made by the people the center of the day’s demonstration. Let the national flag float over every schoolhouse in the country and the exercises be such as shall impress upon our youth the patriotic duties of American citizenship.
    Benjamin Harrison (1833–1901)
