The first presumably means that the entire name is uncertain, but the infraspecific name may be appropriate, the second indicates that the genus is certain, the species uncertain, and the final that the species in certain and only the infraspecific rank is uncertain. To achieve this level of expressiveness, it is recommended that an additional data element '
