Evolution of fruit dehiscence types across the mimosoid clade. Character states were defined as: indehiscent; inertly dehiscent along one or both sutures; explosively dehiscent, whereby the woody valves twist and split along both sutures along whole length of pod simultaneously; elastically dehiscent from the apex, the valves recurving, but not laterally twisting; craspedium, i.e. fruits breaking up into free-falling one-seeded articles leaving a persistent replum or whole valve breaking away intact from replum (valvately dehiscent); lomentiform fruit, i.e. the valves readily cracking between the seeds into one-seeded articles, taken here to include crypto-lomentiform fruits. Branch lengths are not informative in this figure. Photos a–e elastically dehiscent a Acacia argyraea Tindale b Calliandra prostrata Benth. c Calliandropsis nervosa (Britton & Rose) H.M. Hern. & P.
