 | | Spathanthus is sister to all other genera of Rapateaceae, with the tribes Rapateae and Monotremae representing successively divergent lineages within Rapateoideae. |
 | | Saxofridericia/Stegolepis/ Epidryos/Marahuacaea, which have yellow, cup-shaped flowers and bee pollination, are sister to the tribe Schoenocephalieae, which have reddish, tubular flowers, the only nectaries in the family, and hummingbird pollination. |
 | | Branch lengths are consistent with the operation of a molecular clock; Maschalocephalus is only slightly divergent from other Monotremae, suggesting that it is the product of a relatively recent, long-distance dispersal event, NOT continental drift. |
