Belongs within: Apocynoidina.
Contains: Periplocoideae, Echiteae, SarcostemmaDuvaliaEchidnopsis, Asclepiadoideae.

The Euapocynoidina were defined by Sennblad & Bremer (2002) as the largest clade within Apocynaceae including Apocynum and Echites but not Malouetieae, Wrightieae or Nerieae. They are united by the possession of anthers that are adnate to the style head both by the retinacle and by the thecae (Sennblad & Bremer 2002).

As well as more traditionally apocynaceous taxa, the euapocynoids include the milkwort clade Asclepiadacina, previously treated by many authors as a separate family Asclepiadaceae. In most Asclepiadacina (except Baissea) the pollen is agglutinated into pollinia that are connected to a clasping translator. The Secamonoideae are characterised within the Asclepiadacina by four pollinia per translator (Sennblad & Bremer 2002).

The Apocyneae are a clade of species with a style head lacking a stigmatic hollow, in combination with thecae adnate to the style head. The Mesechiteae have anthers with obtuse, truncated tails and a retinacle lacking hairs, and also a strongly pentagonal style head with a stigmatic hollow (Sennblad & Bremer 2002).
