چکیده انگلیسی
The secondary tissues of both species are characterized by a high portion of parenchyma (around 45%). Sometimes irregular growth rings were recognized that may reflect some kind of seasonality and/or environmental influence. We suspect the leafy branches, which were free of any secondary growth in both species, were probably grown and abscised seasonally. Comparisons are made with both different calamitean species and other preservational forms.
