The contribution of embryogeny to the systematics of Polycarpi cae and Helobiae
Abstract
The study of embryogenesis in 27 genera of Polycarpicae and Helobiae allows to determine the embryological characters of these two taxa and determine their phylogenetic bonds by comparison with other morphologic criteria. This study suggests that 'there is no direct relationship between Ranunculales and Helobiae, whereas the latter, in spite of their appearance, show some relationship with Magnoliaceae.
