Monopodial stem with once-pinnate compound leaves and pseudostrobili forming a crown. Stem eustele with pith; cauline primary xylem strand adaxially curved; secondary xylem pycnoxylic; leaf traces tangentially elongated.

Pinnules with radiate venation, arranged in four rows, with two rows of large, lanceolate pinnules on lower surface, two rows of small, oblong pinnules on upper surface of the axis. Pseudostrobilus heterosporous; sporophylls whorled, proximally disk-shaped or dissected into segments, distally upturned and dissected.
