Table 5.

Counts of genera with indicated haploid (gametic) chromosome numbers, by subfamily or clade.

Each cell (except for the count summaries in the last three columns) contains the number of genera with a chromosome count indicated (column), for that clade (row). For example, in the Caesalpinioideae (which includes the mimosoid clade), 31 genera have a chromosome count of 13. (For most genera, all species have the same chromosome count, but where count differences are reported in the literature, the modal value is used for the genus). For each clade, the most frequent chromosome count is highlighted in bold, and the most frequent count values are listed on the right. Species and count details are given in Supplementary Table S2.
