Seven years old Sengon (Paraserianthes falcataria) and Jabon (Anthocephalus cadamba) trees were harvested from plantation forest in West Java, Indonesia aiming to characterize radial pattern of selected physical and anatomical properties. One disk from log section in length of 2m (bottom part) and 6m (upper part) was taken from each tree of the tree stem, the sample from pith to bark (2.6cm x 2.0cm) was prepared from disk. Each sample was divided in 1cm wide segments (segmented ring) numbered from pith to bark. Anatomical parameters and density were measured for each segmented ring to investigate the juvenile and mature pattern of radial variation for each property. Observed patterns were described using three different models: I linearly increase or decrease, II exponential, III lineary equal to intercept. By using measured profiles, a typology of variations was defined from statistical modeling. The pattern of radial variation showed in both species, all properties in vessel elements (vessel frequency and vessel area), fiber length and density in Jabon had model II. Lumen diameter, cell wall thickness and density in Jabon had model I and also for fiber diameter of bottom part in both of species, diameter lumen of upper part Sengon and cell wall thickness of bottom part Sengon. Model III had found in fiber diameter of upper part in both species and lumen diameter of bottom part Sengon.
