Stems of tree ferns of the Order Marattiales and Family Psaroniaceae are abundant in the
fossiliferous record of the Parnaíba Basin, at the Integral Conservation Unit Tocantins Fossil
Trees Natural Monument, and are represented by Psaronius sp. and Tietea sp. Specimens
collected in 2007 favored the description of petioles; through the anatomy and morphology of
the vascular bundles, three specimens were selected and described by means of cross-section
analysis using a stereomicroscope. Achieving the results of diverse morphology forms and
varying cell lengths. The descriptions provided in this work contribute to the presentation of
new genus and species in the literature and indicate a relationship of origin with the stems of
the genus Tietea sp. |
