Surface with narrowly rounded longitudinal leaf cushion ribs ; 

 about 80 cm from the base of the tree. 



Detail from area, a little higher, in which the cushions are in a 

 distinctly costate arrangement on the right (near the middle 

 of the stem), though on the left they assume a rhomboidal 

 form, an aspect like those of Lepidodendron. The leaf scars, 

 including the parichnoian cicatricules, are more distinct on the 

 ribs, whose sharp configuration is probably due in part to 

 lateral pressure. 



Fragment of the impression of the counterpart, or upper side of 

 the stem, at about 90 cm above the base, showing favularian 

 cushion rows, with traces of hypodermal strands along the 

 intermediate furrows.
