Sequential (‘automatic’) reiteration and gradual trends in architectural, morphological and anatomical features according to stages of development. (A) Trends in leaf size and form for the main axis during the ontogeny of Artocarpus elasticus (from Edelin, 1984). (B) From left to right: trends in stem and leaf anatomy, in leaf and short shoot size and structure, in a main stem branching complexity (branching grade) and size (length of the latest G.U. in black and position of short shoots in dark grey on maximum expanded branching system in grey) and in architecture according to successive stages of development in Fagus sylvatica (after Nicolini, 1997; Nicolini and Chanson, 1999).
