Although most of the features of the genus diagnosis are compatible with our fossil, some differences have to be pointed out: the aliform to confluent parenchyma with only a few vessels, marginal ray cells can be subdivided and contain crystals (presence of which is ambiguous in the present fossil as it is hard to determine if crystals belong to ray cells or the underneath axial parenchyma cells). Moreover, intervessel pits are vestured in previously described specimens of
