Abstract

For land-based plant communities four divisions of potential restraints on growth exist, viz. climatic, topographic, edaphic and biotic restrictions (Watts 1971). Of these four, climatic restrictions are usually the most important — certainly for biogeographical and ecological studies on a subcontinental scale — for plants depend directly or indirectly on the atmosphere for certain fundamental materials, for their successful growth and reproduction. Different species, for instance, vary in their minimum requirements for, and in their tolerance of, particular climatic conditions and these conditions therefore play a major role in determining where a particular plant can or cannot exist (Tivy 1971).
