Comparative embryology of basal angiosperms.
Recent phylogenetic analyses of basal angiosperms have identified those lineages central to the study of the origin and early diversification of flowering plants. As we begin to understand the early evolution of endosperm developmental patterns in flowering plants, it is apparent that we know little about the other basic embryological features of basal angiosperms, such as the nature of the female gametophyte and even whether a process of double fertilization occurs.
