Crataegus sylvestris is listed in the index without an authorship and has a reference to p. 96 (C. pyrifolia subsp. sylvestris Schuette). It is construed here that it is the journal’s practice to index all epithets under the genus name regardless of rank; therefore, the intention to publish the taxon at the rank of species in the index is not demonstrated.
