Engler system
From Wikipedia, the free encyclopedia
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
- 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).
