Magnoliid clade - Laurales

This clade comprises predominantly tropical, woody angiosperms. They share flowers with many spirally arranged stamens and predominantly apocarpous gynoecia with many pistils that develop into single-seeded fruitlets.



Calycanthaceae - A small family of four genera, of which Calycanthus is the only North American one. Double fertilization absent; the endosperm is exclusively maternal in origin. [use your browser's BACK button to return to this page]
