The ability of Australian native metallophytes to tolerate extreme metal concentrations in the soil and other difficult edaphic conditions is still not well understood. Copper is an essential micronutrient for plants to survive, but at high concentrations (> 20 µg g⁻¹) in plant tissues, it can cause foliar chlorosis, stunted growth, and ultimately plant death. The Roseby Corridor in Central Queensland (near Cloncurry) is host to copper metallophytes (Polycarpaea spirostylis, Bulbostylis barbata, Tephrosia virens, Eriachne mucronata) which are able to tolerate soils with total copper concentrations up to 12,700 µg g⁻¹_. Even with these high levels of copper in the rhizosphere, the maximum copper in all species is relatively low when compared to Cu concentrations in the soil (leaf/stem: Bulbostylis barbata: 40.9 µg g⁻¹, Eriachne mucronata: 12.3 µg g⁻¹, Polycarpaea spirostylis: 10.9 µg g⁻¹, Tephrosia virens: 128 µg g⁻¹). Therefore, all of these species can be classified as copper Excluder-type metallophytes. Their affinity to copper makes these metallophytes useful indicators of copper surface mineralisation within the Roseby Corridor.

澳大利亚原生金属植物对土壤和其他困难的土壤条件中的极端金属浓度的耐受能力仍未得到很好的理解。铜是植物生存所必需的微量营养素，但是在植物组织中高浓度（> 20 µg g ^-1）时，铜会导致叶绿化，生长受阻，最终导致植物死亡。所述Roseby走廊昆士兰中部（克伦克里附近）是主人对铜metallophytes（白鼓丁属spirostylis，球柱草属半枝莲，灰叶霉，鹧鸪草属mucronata），其能够耐受与总铜浓度土壤高达12700微克克^-1 _。即使根际中的铜含量很高，与土壤中的铜浓度相比，所有物种中的最大铜含量还是相对较低的（叶/茎：Bulbostylis barbata：40.9 µg g ^-1；Eriachne mucronata：12.3 µg g ^-1，白鼓丁属spirostylis：10.9微克克^-1，灰叶霉：128微克克^-1）。因此，所有这些物种都可以归类为铜排除型金属植物。它们对铜的亲和力使这些金属植物成为Roseby走廊内铜表面矿化的有用指示。
