Bentham and Hooker
A taxonomic system, the Bentham & Hooker system for seed plants was published in :
The system recognises the following main groups:
Note that this system was published well before there were internationally accepted rules for botanical nomenclature. It indicates a family by "ordo"; an order is indicated by "cohors" (in the first two volumes) or "series" (in the third volume); in the first two volumes “series” refers to a rank above that of order. Terminations for families are not what they are now. Neither of these phenomena is a problem from a nomenclatural perspective: the ICBN provides for this.
Note: This is a selected list of the more influential systems. There are many other systems, for instance a review of earlier systems, published by Lindley in his 1853 edition, and Dahlgren (1982). Examples include the works of Scopoli, Batsch and Grisebach.
