Description max 80 words

Maxwell T. Masters presents a comprehensive scientific account of plant deviations, exploring how flora diverge from standard construction through cohesion, adhesion, fission, and metamorphosis. This 1869 volume offers detailed illustrations and rigorous botanical analysis, appealing to scholars and enthusiasts of natural history seeking insight into the variability and structural anomalies of the plant kingdom.

Vegetable Teratology, authored by Maxwell T. Masters, M.D., F.L.S., serves as a comprehensive catalog of the principal deviations from the usual construction of plants. Published in 1869 for the Ray Society, the work systematically investigates botanical anomalies, distinguishing them from normal variations to understand the laws governing plant morphology. The text is organized into four distinct books, each addressing a specific category of deviation: arrangement, form, number, and size/consistence. The first book examines deviations in organ arrangement. Masters details the union or adhesion of parts, such as fasciation (flattened stems) and synanthy (fusion of floral organs), alongside their independence through fission and dialysis. He also explores alterations in position, including displacement of leaves and flowers, heterotaxy (adventitious growth in unusual locations), and heterogamy (changes in the position of male and female flowers). The second book focuses on deviations in form, covering stasimorphy (the persistence of juvenile structures), pleiomorphy, and metamorphy. This section extensively documents phyllody, where floral organs transform into leaf-like structures, and other metamorphoses where petals become sepal-like or stamens become pistil-like. The third book addresses deviations in the number of organs. Masters describes the multiplication of axile and foliar organs, such as the addition of extra carpels or whorls of petals, as well as the suppression of organs like stamens or petals. He notes that increased numbers often result from luxuriant growth or the development of rudimentary florets. The fourth book covers deviations in size and consistence, including hypertrophy (enlargement), elongation, and enation (growth of warts or excrescences), as well as atrophy and degeneration where parts become scales or hairs. Throughout the volume, Masters relies on extensive illustrations and references to contemporary literature to support his observations on diverse species, including orchids, roses, tulips, and various fruit trees. The work concludes with general conclusions on morphology, discussing homology, co-relation, and compensation, followed by an appendix on double flowers. Vegetable Teratology stands as a foundational reference for understanding plant variability, providing detailed insights into the structural anomalies that challenge the standard botanical construction.
