Barleria rigida var. ilicina with elliptic-ovate or ovate leaves appears to be an intermediate taxon between B. rigida var. latibracteatus and B. rigida var. rigida. It is differentiated from B. rigida var. latibracteatus by its hardened narrow single-veined bracteoles while it is differentiated from B. rigida var. rigida by its ovate leaves and conspicuously spiny sinuate leaf margins (with spines evenly distributed).
