Ionidium from South America were studied by SEM (scanning electronic microscopy). Three different levels of sculpture were observed on the seed coat. The micro-morphological patterns showed great variation between the species and should be considered as additional characters in future taxonomic treatments. The presence of a conspicuous elaiosome was observed; this structure is well known in the genus Viola and is most likely related to seed dispersal mediated by ants. References Ballard, H.
