Morphometric study of retinacula from the members of Acanthoideae has been done to understand the significance of its shape variation in phylogentic context. The monophyly of the sub-tribes Andrographinae and Barleriinae of Acanthoideae are supported by their unique kinds of retinacular shape. The overlapping distribution of the species of Ruellinae and Justiciinae in 2D scattered plot based on retinacular shape is also supported the link between these two sub-tribes which was established by molecular phylogenetic studies. Therefore retinacular shape variations within Acanthoideae are important for its phylogenetic interpretation. Copyright@ International Science Community Association
