Abstract Iron (Fe) deficiency appears as interveinal or uniform chlorosis of the newest leaves (Figure 1). Older leaves remain green. In palms suffering from chronic Fe deficiency, the entire canopy may be chlorotic (Figures 4 and 5). In severely Fe-deficient palms, new leaflets may have necrotic tips, growth will be stunted, and the meristem may eventually die (Figure 2). Early symptoms in Syagrus romanzoffiana (queen palm), Rhapis spp. (lady palms), and some Licuala spp. may appear as chlorotic new leaves covered with green spots 2 to 4 mm in diameter (Figure 3).
