Engler System

One of the prime systems of plant taxonomy, the Engler system was devised by Adolf Engler.

According to Engler, Syllabus der Pflanzenfamilien (1924) the main groups of plants are:

• I. divisio Schizophyta
• II. divisio Phytosarcodina
• III. divisio Flagellatae
• IV. divisio Dinoflagellatae
• V. divisio Bacillariophyta
• VI. divisio Conjugatae
• VII. divisio Chlorophyceae
• VIII. divisio Charophyta
• IX. divisio Phaeophyceae
• X. divisio Rhodophyceae
• XI. divisio Eumycetes
• XII. divisio Embryophyta asiphonogama

  1 subdivisio Bryophyta

  2 subdivisio Pteridophyta

• XIII. divisio Embryophyta siphonogama

  1 subdivisio Gymnospermae

  2 subdivisio Angiospermae

  1 classis Monocotyledoneae

  1. ordo Helobiae
  2. ordo Triuridales
  3. ordo Liliiflorae
  4. ordo Juncales
  5. ordo Bromeliales
  6. ordo Commelinales
  7. ordo Graminales
  8. ordo Principes
  9. ordo Synanthae
  10. ordo Spathiflorae
  11. ordo Pandanales
  12. ordo Cyperales
  13. ordo Scitamineae
  14. ordo Microspermae

  2 classis Dicotyledoneae

In modern classifications, Engler's divisions I - XI are not considered plants but are classified in other groups (although some botanists do accept Engler's divisions VII and VIII, the "green algae", as plants).
