  1. Ca, K, Na, Mg, and P contents are presented as g kg−1 DW; K/Na mass ratios are calculated from weight. Species are abbreviated: C. canescens (can), C. hispida (his), and C. tomentosa (tom). Sample size was n = 8 for the element analysis. Different letters indicate significant differences in element content (Tukey HSD post hoc test, p < 0.05)
