The combination of characters present in this taxon: small pentamerous flowers with cupulate hypanthium ending in a thick presumably nectariferous rim, triangular sepals with a prominent midvein or keel, thin clawed cucullate petals alternating with the sepals, and stamens opposite to the petals is not found in the Solanaceae or even in the Asteridae, but in the Rhamnaceae, a family that is today classified with the Order Rosales in the Rosid clade (APG, 1998, 2003).

For example, let us accept that the name Asteraceae is to be defined as "the taxon at the rank of family inclusive of the genus Aster:" Let us also assume that the taxonomist, using the name Asteraceae, constructs a cladistic classification from a well-resolved phylogeny for the Asteridae. Under this scenario, the definition of Asteraceae does not indicate to the worker to which dade the name Asteraceae should be applied.
