Does manganese play a role in the distribution of the eucalypts?

Abstract

Two subgenera, Symphyomyrtus and Monocalyptus, within the genus Eucalyptus have been traditionally regarded as nutritionally different, although comparisons in the literature of foliar concentrations of nutrients in symphyomyrts and monocalypts do not support this hypothesis for the major nutrients N, P and K. However, the literature shows that concentrations of Mn in the leaves, stem and bark of symphyomyrts are consistently greater than those in monocalypts. The greater concentration of Mn in leaves of symphyomyrts compared with monocalypts was confirmed in both field and glasshouse studies and therefore appears to be a general response. However, in paired sites at the Black Range State Fo..
