Abstract

Nine genera of fossil palm and palm-like leaves are recognized in this study. Amesoneuron H. R. Goeppert, Bactrites E. W. Berry, Palmacites A. Brongniart, Phoenicites A. Brongniart, and Sabalites G. Saporta are considered to be true palms. Some specimens, because of their uniquely recognizable characteristics, have been identified with the modern genus Phoenix Linnaeus. Sanmiguelia R. W. Brown, Paloreodoxites F. Knowlton and Propalmophyllum O. Lignier are also included in this study because of their superficial resemblance to palms. However, they lack one or more characters essential for their recognition as true palms (i.e. hastula, primary costa, and two orders of venation paralleling a prominent but uniform mid-vein in the individual segments). A diagnostic key and a synopsis of accepted form and organ genera, with appropriate synonymies and new combinations complete the paper. A list of genera to be excluded from the Palmae is appended.
