Fig. 6. Age at onset of dormancy (A), % flowering (B) and panicles per plant (C) in P. bulbosa plants with leaves of different shape (C, curved, n = 55; sC, slightly curved, n = 34; S, straight, n = 52) or colour (gy, grey, n = 66; gy‐gn, greyish‐green, n = 44; gn, green, n = 31). Populations were sampled along an aridity gradient of 110–810 mm rain year^–1. Data in A and C are means ± s.e.; bars in B are 95 % confidence intervals.
