In further continuing studies, which include more taxa and additional genes, resolution at the interface is still unsatisfactory (Potgieter & Albert, 1 998b; Potgieter, 1999), and there is even some indication that the asclepiads may be biphyletic (Sennblad, pers.
The combination of Cryptorneria and Cunninghamia as sister taxa and their branching [ILLUSTRATION FOR FIGURE 8 OMITTED] from a position basal to the Dolmitia-Sciadopitys-Cupressus-Taxodium subclade suggests that the Taxodiaceae may have had a biphyletic origin, because the different genera appear to have originated from different Paleozoic ancestors within the Majonicaceae.
Thus the Taxodiaceae appears to have had a biphyletic origin.
