A taxonomic system for seed plants was published in Bentham and Hooker's Genera plantarum ad exemplaria imprimis in herbariis kewensibus servata definita in three volumes between 1862 and 1883.
4-430: Gamopetalae is an artificial historical group used in the identification of plants based on Bentham and Hooker's classification system. George Bentham and Joseph Dalton Hooker published this as Genera plantarum ad exemplaria imprimis in herbariis kewensibus servata definita in three volumes between 1862 and 1883. As a natural system of classification, it does not reflect evolutionary relationships between plants but
8-418: Is considered as pre-Darwinian as it does not take evolution into account. The Genera plantarum classified an estimated 97,205 species into 202 families and 7,569 genera. 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
12-515: The dicotyledon class into three subclasses; Under that system Gamopetalae is a Sub Class and comprises; Bentham %26 Hooker system George Bentham (1800–1884) and Joseph Dalton Hooker (1817–1911) were British botanists who were closely affiliated to the Royal Botanic Gardens, Kew , in England. Their system of botanical taxonomy was based on the principle of natural affinities and
16-412: Was a useful and popular system of classification based on a dichotomous key especially for the flowering plant groups ( angiosperms ). It was based on key characteristics enabling taxonomic students to quickly identify plant groups based only on physical characteristics. However, it is not a scientific group and is used for identification purposes only based on similar plant characteristics. They divided
