Antirrhineae

In tribe Antirrhineae

The line of evolution is from the less advanced Antirrhinum majus to the more advanced Kickxia aegyptiaca . The latter exhibits a considerable number of advanced characters viz. sepal marginal, petal, staminal and carpel supply evolved from vascular complexes, bilipped corolla tube (2,3), four fertile stamens and one staminode, two ventral carpellary bundles, absence of nectary disc and presence of compitum.

Antirrhinum majus exhibits some of less advanced characters viz. distinct five sepals with sepal median bundles arose from central stele, sepal bundles numerous, five petals, dithecous anthers, five staminal traces, the latter with dorsal carpellary bundles coming from central stele while the lateral carpellary bundles from dorsal carpellary mass. Anarrhinum pubescence and Linaria maroccana are the intermediate spp. of this tribe exhibiting amalgamation between advanced and less advanced characters.
