Summary of leaf Ψ for H. anomalus and H. deserticola. Data for native plants Experiment (1), and the two transplant garden experiments (Experiment 2) are separated by a solid black line. The first letter of all abbreviations refer to species (H. anomalus=A and H. deserticola=D) and for Experiment 1 the month and year are noted. For Experiment 2, the second and third letters refer to treatments: off-dune and NO H₂O (=FN); off-dune and +H₂O (=FY); on-dune and +H₂O (=NY); on-dune and NO H₂O (=NN). Bars are means (n=4–7 for Experiment (1) and n=4 for Experiment (2) ±SE). Standard errors are based on a pooled estimate of the error variance for a one-way ANOVA. Note that H. deserticola transplant data were collected in July 2003 and H. anomalus transplant data were collected in Augusr 2003.
