(a) Seeds from hermaphrodite (hermaph.) carobs are lighter than those from females (ANOVA: F1,26=5.5, p=0.027) but have similar variability (box plot shows median, 1 and 1.5 times the interquartile range, and extremes); (b) Coefficients of variation for 63 species collected from the literature with the overall mean (dotted line), filled square, carob; open squares, other Fabaceae; open circles, non-Fabaceae species; (c) CVs of individual carobs decline with mean seed mass (regression: F1,26=15.9, p=0.0005, R2=0.34), filled, hermaphrodite; open, female.
