- Main stem and axes of the first or
der straight, with 2–6 longitudinal ribs and oblique
slightly curve nodal lines. Stems in the nodes are clear
ly expanded. Axes of terminal order long, unclearly
ribbed, with whorls of bifurcated leaves. Lamina of leaf
terminal segments is undivided, from narrow obcu
neate to linear in shape. The anatomical structure of
stems of different orders is similar and consists of nar
row, long, rarely short tracheids with spiral, annular
and scalariform thickenings both on radial and on tan
gential walls. The tracheid pitting is uniseriate. Pits
round to rectangular in shape, common 7 μm in diam
eter on radial walls, and 6 μm – on tangential walls.
Pith rays were absent.
