Wrightia pubescens, copyright Johannes Lundberg.

Belongs within: Apocynaceae.
Contains: Euapocynoidina.

The Apocynoidina are a clade of flowering plants combining taxa historically separated as the subfamily Apocynoideae and the family Asclepiadaceae. Members of this clade are united by molecular phylogenetic analysis, as well as by the basal part of the anther connective (the retinacle) being adnate to the style head (Sennblad & Bremer 2002). Subgroups include the Wrightieae, characterised by presence of a chalazal and absence of micropylar coma, left contorted aestivation, and absence of air spaces in the anthers (Sennblad & Bremer 2002).
