Thomandersia traditionally has been classified within the family Acanthaceae based on morphology by several authors, including APG I 1998, APG II 2003, and in Schlegeliaceae at APG Website Missouri Botanical Garden, in a list of genera of this family, but Stevens argues further that should be considered out of this taxon by weak support and regarded Thomandersiaceae.^[4]

The genus was elevated to family status, previously by Sreemadhavan 1976 ^[5] and 1977 ^[6] on the basis of leaf anatomy and anther morphology, and more recently by Wortley et al. 2005 ^[7] and 2007,^[8] based on phylogenetic analyses of genetic material.

The genus was described with this name in 1892 by French botanist Henri Ernest Baillon.^[9][1]
