Abstract
  • Silica bodies in short cell epidermal leaf cells of the Early Cretaceous Programinis laminatus (Poales) in Burmese amber are characterized. The great majority are rondels and elongated quadrates aligned horizontally in relation to the leaf axis. Rondel types include circular, elliptical, oblong, long and short forms. Quadrate types include short and long rectangles, trapezoids and pentagons. A comparison of P. laminatus silica bodies with those in extant epidermal leaf cells of the Poales aligns the fossil with the family Poaceae and representatives of the subfamily Pooidae.
