Elementome of Endemic Dolomitic Flora: <i>Pterocephalus spathulatus</i> (Lag.) Coult

Unusual dolomite substrates present a phenomenon known as dolomitophily, which refers to the specificity of the flora that grows on them. Within the dolomitic flora, one of the most widespread plants in Spain is the characteristic species <i>Pterocephalus spathulatus</i> (Lag.) Coult., w...

In addition, it was observed that the plant can accumulate metals in the stem and leaves (TF), thus proving that it is capable of transporting them from the root to the aerial part of the plant.
