Micro X-Ray Fluorescence (μXRF) image of a Glochidion cf. sericeum leaf displaying elemental maps for Ca, Mn, Co and Ni. Scan area is 14.9 × 9 mm, with a step size of 2 μm and a per-pixel dwell of 0.98 ms. The maps were flattened to the Compton map to correct for differences in sample thickness and density. Scale bar 1000 μm.
