Anatomy in P. strombulifera is closely related to the nature of ions in the medium.
Total alleviation of SO42− toxicity occurred when Cl− is present in the medium.
Specific anatomical alterations in root, stem and leaflets were induced by salt-mixture.
Treated plants presented reduction in cortical tissues in response to salt-mixture.
Induced tannin accumulation was directly correlated with the presence of SO42−.
