- Diagnosis
- Fossil tree fern stem with attached petiole bases and adventitious roots. Stem solenostelic, without medullary bundles and sclerenchyma sheath; with margins of leaf gap pointing centrifugally. Cortex narrow, surrounded by hypodermis and epidermis, from where an indument of multicellular hairs emerge. Pith and cortex parenchymatous, with interspersed sclerotic nests and mucilague cells. Petiole bases circular to oval; vascular strand single, with a modified omega-shaped morphology, presenting a wavy morphology due to repetition of V-shaped units. Abaxial arc smaller than adaxial arc. Lateral folds in the abaxial half of the strand, with the superior series approximately five times longer than inferior series. Adventitious roots diarch, presenting inner sclerenchymatous and outer parenchymatous cortex.
