    Study Notes

    Historia Plantarum

    • Theophrastus, a student of Aristotle and Plato, contributed to the field of botany
    • He described habit, duration, inflorescence growth, ovary position, and petal fusion
    • Dioscorides gathered knowledge on medicinal plants and wrote De Materia Medica, which described around 600 species, mostly from the Mediterranean region
    • Dioscorides' work was used until the Middle Ages

    Early Botanical Contributions

    • Pliny the Elder discussed diverse plant topics in Historia Naturalis, including horticultural practices, medicinal uses, plant anatomy, and trees used for timber
    • Albertus Magnus described various garden vegetables and introduced the concept of monocots and dicots in de Vegetabilis
    • Otto Brunfels wrote Herbarium Vivae Eicones, which included illustrated descriptions of plants and their medicinal uses
    • Jerome Bock wrote New Kreuterbuch, detailing around 700 plants and their medicinal uses
    • Leonhart Fuchs wrote De Historia Stirpium, attempting to outdo Brunfels' work and including illustrations of native plants from the Americas

    Developments in Botanical Classification

    • Charles Clusius researched indigenous plants and animals, translated medicinal treatises, and established the Leiden Botanical Garden
    • Matthias de L'Obel emphasized the importance of exact observations in botany and wrote Stirpium Adversaria Nova
    • Gaspard Bauhin attempted to use a binomial system in Prodromus Theatri Botanici and Pinax Theatri Botanici
    • Andrea Caesalpino wrote De Plantis Libri, describing around 1,520 plant species and emphasizing the value of flower and fruit characters over habit
    • John Ray dealt with around 18,000 species and emphasized the importance of considering all plant parts in classification
    • Pierre Magnol developed the concept of "family" and classified plants into 76 families in Prodromus Historiae Generalis

    Modern Botanical Classification

    • Carl Linnaeus is considered the starting point of modern botanical and zoological taxonomy
    • He introduced the concept of binomial nomenclature in Species Plantarum and Systema Naturae
    • Georges-Louis Leclerc de Buffon criticized Linnaeus' artificial classification system and paved the way for evolutionary theory
    • Michel Adanson developed a classification system that emphasized the importance of using a wide range of characters in Families des Plantes
