An anatomically preserved stem from the Carboniferous of Gondwana: Phyllocladopitys petriellae Brea and Césari, sp. nov.

Phyllocladopitys petriellae Brea and Césari, sp. nov. occurs in the early Late Carboniferous Jejenes Formation, Argentina. The description of the taxon is based on one anatomically preserved stem, a few centimeters in diameter. The primary xylem is mesarch. The secondary xylem shows only inconspicuo...
