Hedyotis is a very problematic genus or group of genera. Neither the overall identity and limits of this lineage, nor the evolutionary patterns within it, are at all understood or delineated. Widely differing treatments have long been used in different regions and floras. The situation is far from resolution or even general consensus and so many authors treat the genus very broadly[]. In line with several recent (up to 2013) molecular and phylogenic studies, the Kew ‘World Checklist of Selected Plant Families’ has recognised a number of distinct genera and this is the treatment we are adopting here[].
