Traits related to general fitness and mating system.

Means (and standard deviations) of traits related to general fitness and mating system for four populations of Collinsia heterophylla originating from two regions. For onset of stigma receptivity and timing of anther-stigma contact population estimates were calculated as the floral developmental stage (and 95% confidence interval) when 50% of the plants had receptive stigmas or stigmas contacting the anthers, respectively. N = number of maternal families/plant individuals. Differences between populations and regions were tested for significance using ANOVA with population nested within region (means of maternal families/plant individuals represent individual data points in this analysis).
aArcsine transformed.
bThe day the first plant started flowering represents day 1.
cStage 0 = day of flower opening, stage 1-4 equals the number of dehisced anthers (one per day).
