Fig. 1a, b.

Water absorption by excised leaves or photosynthetic shoots of each species during submergence in deionized water for 180 min (n = 7). a The mean (±SE) foliar uptake quantity standardized by projected leaf area. b The mean (±SE) % increase in leaf water content. The asterisk indicates the foliage of each species a absorbed significantly more than 0 mg H₂O cm⁻² or b significantly increased in leaf water content as determined by a one-sample t-test (α = 0.05)
