Original diagnosis: Davey, 1982, p. 21: Batioladinium pomum
Shape: Basically elongate - ovoidal with some dorso-ventral flattening; broadest in the paracingular region. Apical horn moderately long, slender, gradually tapering and arising relatively abruptly from the main part of the cyst. Typically two low, rounded antapical horns.
Wall: Apparently autophragm only.
Paratabulation: Paracingulum sometimes indicated by alignment of granules. Other paratabulation absent.
Ornament: Increases in coarseness from apical to antapical region. Pitting and low granules are typical of the apical region; the granulation becomes more pronounced towards the paracingulum and particularly on the hypocyst. Irregular spinules and small tubercles may be present here.
Archaeopyle: Apical with deep parasulcal notch; operculum usually remains attached.

Original description: Davey, 1982, p. 21: Batioladinium pomum
The length of the apical horn is typically 1/4 to 1/3 Of the overall cyst length.
