Because of the above-mentioned uncertainties in the region of the interface between the former families we wish to maintain the asclepiads as three subfamilies: Periplocoideae, Secamonoideae, and Asclepiadoideae, with the last further divided into the three tribes: Marsdenieae, Ceropegieae, and Asclepiadeae.
Key characters at the interface of the apocynacs and the asclepiads.
However, because of the lack of resolution at the interface, we believe that it would be injudicious at this stage to include all of the asclepiads in the Apocynoideae, as proposed by Sennblad (1997).
In order to fulfill the criterion of monophyly, Sennblad (1997) proposed that all the asclepiads be included in the Apocynoideae, an arrangement that would at least make the resultant taxon monophyletic.
There are three possible solutions: it is one all-embracing family; all monophyletic units are given the rank of family; or an intermediate limit is drawn between the Apocynoideae and the Rauvolfioideae, with the Apocynoideae and asclepiads becoming the new Apocynaceae and giving the remaining polymorphic Rauvolfioideae groups the rank of family.
In addition, the asclepiads formed a monophyletic group.
Taking the above data into consideration, we find (as suggested informally by Bruyns [1994]) that there is little morphological support for the separation of the Periplocoideae from the remainder of the asclepiads at the level of family.
In the higher asclepiads the corpuscle also has a rigid and much harder consistency.
Preeminent among these thinkers were the members of the Asclepiad medical community on the island of Cos, the most noteworthy of whom was Hippocrates (460-370 B.
