(A) The geographic locations of the six populations that were represented in the seed germination experiment, which collectively span the geographic range (shaded area) of L. fremontii in the Central Valley of the California Floristic Province. (B) The 32 year average (± 1 s.e.) for total precipitation in November (the germination period for L. fremontii) at the locations corresponding to each population included in the experiment (generated from daily precipitation data obtained from the PRISM database). (C) The 32 year averages for the minimum and maximum temperature in November for the geographic position of each population (obtained from interpolated climate data from the Worldclim database).
