Figure 4 from: Noblick LR, Sant'anna-Santos BF (2021) Diversity of leaf anatomy within a single leaflet and between leaflets of four Butia (Arecaceae, Arecoideae) species. PhytoKeys 180: 31-52. https://doi.org/10.3897/phytokeys.180.66018

Figure 4 Anatomical changes of the leaflet margins in a 10 cm region to either side of the leaflet centre: Butia paraguayensis. PVB-SVB = primary vascular bundles transitioning to secondary vascular bundles; SVB-PVB = secondary vascular bundles transitioning to primary vascular bundles. Gone = vascular bundle has disappeared or nearly ended. Scale bar: 0.5 mm.
