FIGURE 2: The cross-sections through the edgerolling on T. cordata (a – d) and erineum on T. tomenosa (e-f) leaves at the early phase of development (a-c) and at the more expanded phase (d – f). Phenolics (deep-red in colour) are localised in the cells of the outer layer of the nutritive tissue of both gall types. Starch grains (arrow) dominate within the cells of hypertrophied parenchyma (d). The P. tetratrichus specimens are localised within distinguishable cavities of roll-gall (b, c, d). The presence of red coloured deposits within eriophyoid bodies (d, arrow) suggests that phenolics can be sequestered. Magnification: 90x (a, b, c, e, f); 180x (d).
