Abstract

This study examines the heterogeneity of the Mn-hyperaccumulative trait in natural stands of the Australian rainforest tree species Gossia bidwillii (Myrtaceae). It is the only known Mn hyperaccumulator from Australia, and has an unusual spatial distribution of Mn in its leaves. G. bidwillii occurs naturally on a range of Mn-containing substrates including ultramafic soils. Leaf samples were collected from individual trees and four small stands, over a longitudinal range of ∼600 km. While no variation in the spatial distribution of foliar Mn was detected, considerable variation in Mn concentration was found. G. bidwillii was shown to accumulate Mn when growing on a variety of substrates, and..
