Biography

In 1807 he was appointed teacher of mathematics at Lund University, in 1812 appointed professor of botany and natural sciences,[1] and was elected a member of the Royal Swedish Academy of Sciences in 1817, and of the Swedish Academy in 1831.

He was ordained a clergyman in 1816, received two parishes as prebend, and was a representative in the clerical chamber of the Swedish Parliament on several occasions from 1817. He was rector magnificus of Lund University 1819-1820 and was appointed bishop of Karlstad in 1835, where he remained until his death.[2] He was the father of Jacob Georg Agardh, also a botanist.[1]

System of plant classification

The Classes Plantarum[3] has nine primary divisions into which his classes and natural orders are grouped. These are, with class numbers;

1. Acotyledonae 1–3 (Algae, Lichenes, Fungi)
2. Pseudocotyledonae 4–7 (Muscoideae, Tetradidymae, Filices, Equisetaceae)
3. Cryptocotyledonae 8–12 (Macropodae, Spadicinae, Glumiflorae, Liliiflorae, Gynandrae)
4. Phanerocotyledonae incompletae 13–16 (Micranthae, Oleraceae, Epichlamydeae, Columnantherae)
5. Phanerocotyledonae completae, hypogynae, monopetalae 17 (Tubiflorae)
6. Phanerocotyledonae completae, hypogynae, polypetalae 18–22 (Centrisporae, Brevistylae, Polycarpellae, Valvisporae, Columniferae)
7. Phanerocotyledonae completae, discigynae, monopetalae 23 (Tetraspermae)
8. Phanerocotyledonae completae, discigynae, polypetalae 24–26 (Gynobaseae, Trihilitae, Hypodicarpae)
9. Phanerocotyledonae completae, porigynae 27–33 (Subaggregatae, Aridifoliae, Succulentae, Calycanthemae, Peponiferae, Icosandrae, Leguminosae)

Each class then contains a number of orders (families). For instance, Liliiflorae contains 11 orders;

• Liliiflorae
  • 43 Asparageae
  • 44 Asphodeleae
  • 45 Coronariae[lower-alpha 1]
  • 46 Veratreae
  • 47 Commelineae
  • 48 Pontedereae
  • 49 Dioscorinae
  • 50 Haemodoreae
  • 51 Irideae
  • 52 Narcisseae
  • 53 Bromeliaceae

Publications

He devoted considerable attention to political economy and as "a leading liberal", he "succeeded in improving and raising the standards of education in Sweden".[4] He also wrote on theological and other subjects, but his reputation chiefly rests on his botanical works, especially Systema algarum, Species algarum rite cognitae and Classes plantarum[3] on biological classification, and Icones Algarum (1824, 1820–28, and 1828–35). The greatest part of his Manual of Botany (2 vols., Malmoe, 1829–32) has been translated into German.[1]
