of organisms in which there is a high level of predictivity, as opposed to artificial classifications, which tend to be very unpredictive. Most taxonomists strive towards the production of natural classifications, although their approaches and interpretations of the data may vary greatly. Natural classifications can best be achieved by exploring the fields of cytogenetics, microanatomy, and phytochemistry in addition to morphology, anatomy, and plant geography, thus broadening the base on which classifications are founded.
Many phylogenists believe that only those classifications based on *monophyletic
taxa are natural.
