Vegetable Teratology / An Account of the Principal Deviations from the Usual Construction of Plants

This work presents a systematic survey of abnormal plant development, cataloguing and explaining principal deviations from typical organization. It organizes anomalies into groups—unions and adhesions of organs, independence phenomena including fission and dialysis, and positional changes such as displacement, prolification, and heterotaxy—and examines causes, variants, and illustrative cases. The author draws on published records and personal observations, provides detailed descriptions and illustrations, and situates teratological examples within morphological theory and comparative study, aiming to make anomalous forms intelligible rather than mere curiosities.
