A major division of plant science which is concerned with all aspects of the spatial distribution of vegetation: Geographical botany
, plant geography
, and phytogeography
all involve the study of the spatial distributions of plant life and of the environmental relationships which may influence these distributions.
Plant geography has emphasized the mapping of such regions and the interpretation of the terms of environmental (ecological) influences.
