Genome size estimates are least-square means from the ANOVA for that species. Standard error (s.e.) is the same for all genome size estimates within a species. Estimates with the same letter within a species are not significantly different, Tukey's HSD, α = 0·05. Numbers in bold are significant values (P < 0·05).
