Resumen:
Specimens of a new lycopod were colected in the Pallero Member of the late Carboniferous-early Pennian Bajo de Vé1iz Fonnation at the Bajo de Véliz locality (San Luis province). They are undecorticated stems differentiated into steri1e and fertile zones, and dense1y covered by helically disposed microphyles that produced false scars after shedding. Strobilar structures tenninally attached to the stems have also been found. Based on these morphological features a possible relationship of this southem lycopod to the norhtem family Chaloneriaceae is suggested. This new finding enlarges our knowledge on Gondwana lycopods, a group scarcely represented in the southem hemisphere.
