Fig. 5. Proportions (%) of P. bulbosa plants with different leaf shapes (C, curved, sC, slightly curved and S, straight) and leaf colours (gy, greyish; gy‐gn, greyish‐green; gn, green) in populations sampled at arid habitats (110–310 mm rain year^–1, n = 107) and at mesic habitats (500–810 mm rain year^–1, n = 35). Bars are 95 % confidence intervals. Proportions of plants with different combinations of leaf shape and colour were calculated separately for the arid and mesic populations.
