Hier stellen wir eine kombinierte Kiassifikation vor fur die Apocynaceae, mit 424 Gattungen, die in f[ddot{u}]nf Unterfamilien gegliedert sind: Rauvolfioideae, Apocynoideae, Periplocoideae, Secamonoideae und Asclepiadoideae.
Therefore, the statement of Kunze (1996: 576) that "the jump from sticky tetrads to well-defined pollinia could be considered to be quite large," which was used as a justification for separating the Periplocoideae and the Asclepiadoideae at the level of family, is unjustified.
For the Asclepiadoideae he concluded that "the border between a receptacular base of the staminal column and an upper part in which the filaments are fused cannot be made out.
In his later paper Kunze (1996: 567) stated that the filament tube in the Asclepiadoideae has evolved by "replacement of the original free filaments by new elements originating from the inward[ly] protruding base[s] of the filaments.
Another important fact is that while the situation described in the third stage leads naturally (in our view) to that in the Asclepiadoideae, the arrangement in first stage is similar to that in various Rauvolfioideae and Apocynoideae (cf.
Further aspects lend support to the existence of a cline from the Periplocoideae to the Asclepiadoideae.
This situation again bears considerable similarity to many coronas found in the Asclepiadoideae.
In the Asclepiadoideae the primary nectaries are located behind the guide rail at the top of the so-called filament tube and above the filaments.
Morphologically, the Secamonoideae fall somewhere between the Periplocoideae and the Asclepiadoideae and share characters with both of these subfamilies.
However, in the Secamonoideae with functionally bisporangiate anthers, it is the two inner (ventral) ones that are reduced (Civeyrel, 1995, 1996), whereas in the Asclepiadoideae it is the two outer (dorsal) ones that have become obsolete.
That is, the equal locular development TABULAR DATA OMITTED of the Plumerioideae could have given rise to the four-pollinial state in Secamone while the trend towards the underdevelopment of the two adaxial locules in the Apocynoideae (Demeter, 1922) could have resulted, if taken to its ultimate conclusion, in the two-locular state found in the Asclepiadoideae.
