A reconstruction of this plant shows slender, unbranched, densely spaced leafy shoots 1.5 - 2.00 m heigh. Their needle-shaped leaves are very large (up to 30 cm long), bifurcated, single veined, and are decurrent on helically arranged, closely spaced leaf cushions. Dried leaves in hte lower part of the shoots remain attached with their bases to the stems. The plant was monoecious and caulifloral, axially cones consist of spirally arranged bracts, different in shape and size.

(mainly deduced from Barthel et al., 1998): Probably rather shallowly rooted bushes with slender aerial axes up to 2m tall, unbranched or once bifurcate, showing spirally arranged rhombic leaf cushions with permanently attached, repeatedly dichotomised, simple veined leaves. Seed and pollen bearing organs constituting small strobili occur interspersed with and in substitution of leaves; both female and male strobili being found on the same axes. winged seeds of Samaropsis aspect.

Woody, branched plants; shoots bearing elongate-linear leaves, helically disposed, dichotomously divided and univeined. Female organs lax, compound, with sessile or pedunculate ovules placed on leaves or axillary to leaves.

Ce sont, avant tout, des feuilles linéaires de longueur variable, une et deux fois bifurquées d'une manière constante dans une même plan; feuilles, à part cela , plissées en longueur et rappelant un peu, quoique plus courtes et plus étroites, celles des Lépidodendrons et de quelques Sigillaires, mais autrementcoriaces, de nature au moins plus fibreuse et marquées de plusieurs nervures plus fortes, saillantes, et de nervules intermédiaires plus ou moin noyées dans l'épaisseur du parenchyme.
