Developmental and Structural Section Mathieu, Millan [1], Edelin, Claude [2]. Is architectural analysis efficient for the analysis of all growth forms? During the 70’s Hallé & Oldeman presented their architectural models for trees. This essay was not written as an attempt of growth forms classification but it can be seen as a structural classification of trees growth forms. Based on the principles given in Hallé & Oldeman (1970) a method of plant architecture analysis has been developed, but mostly on tree. In this presentation, we investigate if the architectural analysis is efficient for the description of species belonging to different life form than trees. We describe the architecture of 10 species belonging to different life forms such as treelets, bushes, lianas, hemi-epiphytes and herbaceous plants. The architectural analysis of the presented species was performed according to the concepts and recently revisited by Barthélémy and Caraglio (2007). The method consists of (i) selecting individuals at various growth stages from seedling to adult to senescent individuals and (ii) qualitatively describing the structure of all stems for each individual at each stage of development. The structural and ontogenic properties of each species are presented. On the basis of theses descriptions, we discuss the efficiency of architectural analysis for the description of plant belonging to other growth forms than trees, we highlight the common points between the species and we discuss the interest of a structural trait focused approach in growth forms classification research.
