A recent study in the family Linderniaceae - Fischer E.; Schäferhoff B. & Müller K.: The Phylogeny of Linderniaceae - The New Genus Linderniella, and new combinations within Bonnaya, Craterostigma, Lindernia, Micranthemum, Torenia and Vandellia. Willdenowia 43: 209 - 238. December 2013. ISSN 0511-9618 - has proposed moving several genera from Scrophulariaceae into Lindernia; resurrecting the genera Bonnaya and Vandellia from within Lindernia; and describes a new genus Linderniella. These changes have not yet been accepted - if they do then this species will become Vandellia diffusa L.
