Using Wnuk at al. consideration (C. Wnuk - Ontogeny and paleoecology of the middle Pennsylvanian arborescent lycopod Bothrodendron punctatum, Amer. J. Bot., 1989) I calculated the diameter of the stem - some 14,9 cm and length of the stem above this fragment (from these branches to the top of the tree) - some 6,2 meters. New branch and stem detailes:
