There is no clear pattern in the arrangement of the pseudohydrothecae in the material studied. For example, in the material from Stn 17 the pseudohydrothecae are approximately alternate at the basal part of the stems, forming two longitudinal rows. However, they are curved to the same side, forming two planes separated by an obtuse angle. More distally, there are verticils of three or four pseudohydrothecae, roughly forming three or four longitudinal rows. In other parts, the pseudohydrothecae are more irregularly distributed, but can be found all around the stem.
