Data were analysed from just one side of the leaf or leaflet, ignoring the margin and midrib. Leaves were numbered using an indelible marker pen, close to the midrib and c. 1 cm from the petiole. The tents that we observed had cuts in the lateral veins and interconnecting tissue of the leaf along both sides of the midrib. The modified leaves had cuts in the secondary veins and interstitial tissues along the midrib. Thickness of tissue layers was measured from the sections near the midrib using a light microscope with an ocular micrometer.
