Early Efforts at Plant Classification
Theophrastus (370-288 B.C.) may have been the first to publish on the subject
of plant classification in the work called Enquiry into Plants. Here, he classified
plants into four groups. In addition to botany, Theophrastus had a great
many interests, includingt he causes of wind, scents, and sensations; physics;
ethics; politics; and history. Another of his writings was entitled On the Causes
of Plants. Dioscorides (fl ca A.D. 5) compiled Materia Medica, which illustrated
500 plants of supposed medicinal value. At one time, a plant name was
actually a description of the characteristics of the plant. This often required
the equivalent of an entire sentence and was thus a burdensome system.
