Eichler system

A system of plant taxonomy, the Eichler system was the first phylogenetic (phyletic) or evolutionary system. It was developed by August W. Eichler (1839–1887), initially in his Blüthendiagramme (1875–1878) and then in successive editions of his Syllabus (1876–1890). After his death his colleague Adolf Engler (1844–1930) continued its development, and it became widely accepted.

A. W. Eichler

The system was based on dividing the plant kingdom into those plants with concealed reproductive organs (non-floral), the (Cryptogamae, = hidden reproduction) and those with visible reproductive organs (floral), the (Phanerogamae, = visible reproduction). Moreover, Eichler was the first taxonomist to separate the Phanerogamae into Angiosperms and Gymnosperms and the former into Monocotyledonae and Dicotyledonae. His primary ranks were Divisions (Abtheilung), followed by orders (Reihe).

Blüthendiagramme (1875–1878)

Volume I (1875)

Contents pp. VI–VIII
Synopsis:

• Division I Gymnospermae p. 54
• Division II Monocotyledoneae p. 73
• Division III Dicotyledoneae p. 187 (part)

Volume II (1878)

Contents pp. V–VIII
Synopsis:

• Division III Dicotyledoneae p. 187 (continued)

Syllabus (Fourth edition 1886)

The system (here taken from the 4th edition of the Syllabus, 1886) divides plants into divisions, classes and groups. Groups were further divided into orders.
