Table 2.

Species are listed with family, geographic origin, growth habit, and calculated pressure–volume curve parameters, including water potential at turgor loss point (Ψ_tlp), modulus of elasticity (ε), osmotic potential at full turgor (π _o), and the relative water content at turgor loss point (RWC_tlp)
