The following points highlight the three main lines of evolution in angiosperms. Angiosperm: Evolution # 1. The First Line: I. It consists of Rhoeadales, Sarraceniales, Parietales, Malvales, Geraniales, Sapindales, Rhamnales and some Tubiferales. In this case the hypogynous condition remained unchanged. II. Labiatae is the most advanced family of this line. It is characterized by fusion of sepals, petals and [...]
