Rungia latior Nees var. anamalayana Chandrab. & V. Chandras., examined as part of the revisionary studies on the Acanthaceae of Western Ghats, have shown some taxonomic ambiguity. As the original authors rightly pointed out, the variety ‘does not fit within the circumscription of the typical species’. Based on our recent collections, we also felt that the varietal status is superfluous as the same has got some merits to be recognized as a distinct species. As such the status of the variety has been reassessed; elevated to the specific rank and a new combination has been set, conserving the varietal name as the specific epithet. Accordingly, the species is renamed as Rungia anamalayana (Chandrab. & V. Chandras.) A. Nazarudeen & G. Rajkumar comb. et stat. nov. The distinctive features and alliance of the species is discussed and a full account of the species is presented with illustrations.
