Studies were made in forests already described in three plots of contrasting density and site index: (a) 1600 stems/ha, site index 40; (b) 8600 stems/ha, 60; and (c) 3800 stems/ha, 90. Foliage biomass and surface area were measured on felled sample trees in five d.b.h. classes. Although the mean dry weight of fascicles varied with dominance, crown position and fascicle age, no consistent pattern of variation was found in all three plots.
