ment an investigation of ovule and seed structure in Achariaceae. a tri-generic family comprising three species of herbaceous
perennials endemic to southern Africa. Tests for myrmecochory suggest that seed of Ceratiosicyos Nees is not dispersed by ants
like those of Acharia Thunb. and Guthriea Bolus. Structural differences include the absence of a raphal ridge and imbibition lid
and the presence of long funicles and medium-sized embryos in Ceratiosicyos.
