Abstract

Anatomy is described of three new organ genera-stem, petiole and leaflet of petrified cycadean plants. In addition, information about a bisexual bennettitalean fructification is given and free nucelli of conifer seeds are recorded. Comparison and critical remarks are given on the fossil plants included in this paper.
