Ovuliferous cone consisting of decussately arranged ovuliferous complexes. Each ovuliferous complex lanceolate, with broad base, and pointed apex consisting of a bract and ovuliferous cone scale that is differentiated into woody basal part and parenchymatous and bulging apical part. Ovuliferous scale bearing single inverted seed, covered by parenchymatous and bulging structure. Margins of basal parts of bract with marginal papillae. Terminal ovuliferous complexes consisting of sterile bracts, devoid of seeds. Stomata on adaxial cuticle surrounded by structures resembling Florin rings. Seed wall consists of thickly cutinised cells.
The specific epithet lusitanica is derived from Lusitania, the name for the imperial Roman province covering the central part of Portugal, where the fossil specimen was collected.
