Although the pollinia were traditionally considered to be attached directly to the corpuscle in the Secamonoideae, recent studies in Secamone (Civeyrel, 1995, 1996) have shown that in several cases there is a short caudicle between the pollinia and the corpuscle.
The statement that the pollinia are attached to the caudicle at their apex is not correct for the Asclepiadeae.
The Fockeeae was separated from the Marsdenieae by the lack of caudicles and the lack of a floor in the lower third of the corpuscle.
Upon removal of whole pollinarium by a pollinator the pollinia may change their angle of orientation as the caudicles and/or stipes dry out and change positions (see also, Darwin, 1877).
The fact that the Periplocoideae, Secamone, and Fockea Endlicher all lack structures that could be precursors of the caudicles or translator arms found in the rest of the Asclepiadaceae also lays a monophyletic evolution open to some doubt.
