Description
They were forest trees with almost horizontal standing leafy lateral shoots and with vertical tribes. They were generally small trees.[2] At least with Utrechtia piniformis the side shoots are in whorls.[3]
Like other Voltzialean plants, they had compact ovulate cones bearing bilateral bract-scale complexes. The leaves are scale-like, arranged spirally and only a few millimeters long.
