Foliar epidermal features of three known taxa of Fittonia Coemans belonging to the family Acanthaceae have been studied. The genus shows typical features of Acanthaceae (sub‐family Acanthoideae) like diacytic stomata, sub‐sessile glandular hairs with globular head and the presence of cystoliths. While all the three taxa show broadly similar epidermal features, there are distinct variations which help in distinguishing them from one another. The presence of ocelli (lens cells) on the upper epidermis of F. verschaffeltii var. pearcei is significant and indicates that the latter might be a distinct species.
