Ecological studies upon a physiognomic basis

Resumo

Published descriptions of vegetation-types in the American tropics have not so far been very numerous. We know less scientifically about the tropical regions. Studies of this kind are gradually increasing, however, and it will eventually be possible to piece together a complete picture of the vege-tation, framing a classification into which all the types will fit, and which will clarify their 'ecological relationships. This epoch will be brought nearer if we ensure that ecological studies give us all the information we require, presented in the right manner, and do not omit to deal with important questions.
