Abstract

Logically we have in geobotany three great problems of research: space, habitat, and change; and two objects of study: the plant and the plant community. That gives us six branches of our science: (1) autochorologic geobotany; (2) autecologic geobotany; (3) autogenetic geobotany (combining with the study of the flora); and (4) synchorologic geobotany or chorologic sociology; (5) synecologic geobotany or ecologic sociology; (6) syngenetic geobotany or genetic sociology, study of succession (combining with the study of vegetation or plant sociology). Historically plant geography, plant ecology, and geobotany are synonymous and include all six branches. Geobotany (Grisebach) always does this; the two other terms are ambiguous, because often used in narrower and wider senses. The different meanings are discussed.
