text: Theophrastus (390–280 BC) was a disciple of Aristotle and a philosopher of natural history, considered by historians as the Father of Botany. He wrote a treatise entitled Historia Plantarium about 300 BC. It was the first attempt to organize and classify plants, plant lore, and botanical morphology in Greece. It provided physicians with a rough taxonomy of plants and details of medicinal herbs and herbal concoctions.
