Diagnosis

Bifariala with a spoon-shaped, narrowly elliptical to lanceolate receptacle. Primary wing broadly fluted and finely striate perpendicular to receptacle margin, contracted and discontinuous at the apex, forming a rounded lobe on either side of pedicel at base of receptacle. Robust secondary wing broadest in apical region; acute to acuminate apex; base narrowly tapered toward pedicel; bearing fine striae arched towards apex. Attached Glossopteris leaf with cuneate base and obtuse apex; midrib persistent and well defined; lateral veins emerging acutely, arching gently and continuously across lamina, sparsely anastomosing, forming narrow meshes at an angle of about 50° to midrib.
