Plants that naturally accumulate aluminium (Al) may also inadvertently accumulate rare earth elements (REEs) due to the similar chemical properties of Al and REE trivalent ions, and vice versa. In this study, an Al hyperaccumulator plant species, Melastoma malabathricum, and a species known to have a propensity to hyperaccumulate REEs (in addition to Al), Dicranopteris linearis, were evaluated for potential REE accumulation in a one-year pot dosing trial in Sabah, Malaysia. To test whether the Malaysian accessions of D. linearis and M. malabathricum hyperaccumulate REEs (and Al), both species were grown in pots containing soil treated with solutions containing yttrium (Y), lanthanum (La), neodymium (Nd), and a mixture of these three REEs. The results showed that both M. malabathricum and D. linearis accumulated > 1000 µg g⁻¹ Al in their leaves as expected. The shoots of M. malabathricum contained lower REEs than the roots (50 µg g⁻¹ compared to 905 µg g⁻¹). In D. linearis, the mean foliar REE concentrations ranged from 145 to 315 µg g⁻¹, which is below the hyperaccumulation threshold set for REEs (> 1000 µg g⁻¹ REEs). This study revealed that the Malaysian accessions of both M. malabathricum and D. linearis are Al hyperaccumulators, but their REE hyperaccumulation status requires further testing.

自然积累铝（Al）的植物也可能​​由于铝和稀土元素REE（三价离子）的相似化学性质而无意中积累了稀土元素（REE），反之亦然。在这项研究中，在沙巴州进行了为期一年的盆栽剂量试验，评估了Al过度富集植物物种Melastoma malabathricum和一种已知具有超高积累REE倾向的物种（除Al之外）Dicranopteris linearis。 ，马来西亚。测试马来西亚的D. linearis和M. malabathricum加入超富集稀土元素（和铝），两个物种都在装有土壤的盆中生长，这些土壤经过含钇（Y），镧（La），钕（Nd）和这三种稀土元素的混合溶液处理。结果表明，按预期，M。malabathricum和D. linearis的叶片中积累的铝> 1000 µg g ^-1 Al。的芽M. malabathricum含有低稀土元素比根部（50微克克^-1相比905微克克^-1）。在线性线虫中，平均叶片REE浓度范围为145至315 µg g ^-1，低于为REEs设置的超积累阈值（> 1000 µg g ^-1REEs）。这项研究表明，马来西亚马拉巴毛霉和线虫D.的种质 都是铝的超积累物，但是它们的稀土超积累状况需要进一步测试。
