Original diagnosis: Davey, 1982, p. 21: Batioladinium radiculatum
Shape: Basically elongate, dorso-ventrally flattened; broadest in the paracingular region. Apical horn long, gradually tapering and proximally merges with the main part of the cyst body; distal part is solid with internal vacuoles. Two relatively short antapical horns are present; they taper rapidly distally and are strongly vacuolate throughout. They may give rise to irregular branches or may be bifurcate.
Wall: Apparently autophragm only.
Paratabulation: Paracingulum may be defined by aligned granules.
Ornament: Epicyst mainly smooth to lightly punctate. Granules and tubercles gradually start to appear towards or in the paracingular region and become more abundant on the hypocyst.
Archaeopyle: Apical with deep parasulcal notch.
