[3] The trunks of this plant are solitary, spherical, or reach up to 1.2 meters in height and 60 cm in width.

These leaves are 0.9 - 1.8 meters long and 34 - 44 cm wide, with a flat surface, a rounded tip, and a base that narrows abruptly.

The leaflets are arranged in 30 to 70 pairs and do not overlap, dull green, flexible, and either straight or bent forward.

The stem of the male cones is 15 - 17.5 cm long, hairy, and dull yellow-green with deep red spots.

The sporangia, which are the structures that produce spores, are arranged in a single, somewhat heart-shaped spot within the cone.
