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.
