Lindley system

Taxonomic system of plant classification, by John Lindley (1799–1865) From Wikipedia, the free encyclopedia

Remove ads

An early system of plant taxonomy, the Lindley system, was first published by John Lindley as An Introduction to the Natural System of Botany (Natural History, 1830).[1] This was a minor modification of that of de Candolle (1813).[2] He developed this further over a number of publications, including the Nixus plantarum (1833)[3][4] and a second edition of Natural History (1836), in which he introduced the concept of a higher order of taxonomic rank, the Alliances, in which he embedded the Tribes (families).[5][6] He also expanded his ideas on Exogens in his entry of that name in the Penny Cyclopedia (1838).[7][8] In 1839 he revised his division of the plant kingdom into classes in an article in the Botanical Register.[9][10] Lindley's system culminated in the three editions of his Vegetable Kingdom (1846, 1847, 1853).[11][12][13]

The schema of the Natural History is shown on pages xxxv and xxxvii-xlviii.[14] In the Vegetable Kingdom,[13] the schema for the first edition is on pp. lv–lxviii. The third and final edition was published in 1853,[13] with the schema on p. lv.[15] Cross references from Natural History to Vegetable Kingdom in [Square brackets].
