sentences:  The Bennettitales bore remarkably flower-like organs, protected by whorls of bracts which may have played a similar role to the petals and sepals of true flowers; however, these flower-like structures evolved independently, as the Bennettitales are more closely related to cycads and ginkgos than to the angiosperms.However, no true flowers are found in any groups save those extant today.Most morphological and molecular analyses place "Amborella", the nymphaeales and Austrobaileyaceae in a basal clade called "ANA".
