|Abstract||Each plant can be recognized by its general shape. Nevertheless, this physiognomy is the result of a very precise structure that expresses the existence of a strong organization. The architecture of a plant depends on the nature and relative arrangement of each of its parts; it is at any given time the result of an equilibrium between endogenous growth processes and the constraints exerted by the environment. Architectural studies have been carried out for some twenty years and have led to the definition of several concepts that provide a powerful tool for studying plant form. The results obtained in this field show that the architecture of a plant can be summarized by a small number of elementary structures: internode, growth unit, axis, architectural model,... In the course of ontogenesis, these structures are repeated and reveal several levels of organization that seem to be only different stages of a common process of growth and transformation|
