Is Cephalotus a more evolved Nepenthes? Are they related in any sense? They seem very familar that is pitcher attachment
but isn't similar in flowers, those useless traps. could be a ancient form of nepenthes or a more evolved?
In what respect are the traps "useless?" They still function as pit-fall traps like those of other pitcher plants.
As has been mentioned, cephs are not closely related to any of the other cps. In the murky science that is taxonomy, according to the ITIS:
cephs belong to the CLASS: Magnoliatae (aka Magnoliopsida),ORDER: Rosales indicating they are distantly related to such plants as magnolia and roses.
Dionaea muscipula belong to the CLASS Magnoliopsida, SUPERORDER: Caryophyllanae (which includes carnations), Order Caryophyllales, Family Droseraceae
Drosera belong to the CLASS Magnoliopsida, SUPERORDER: Caryophyllanae , Order Caryophyllales, Family Droseraceae
Neps belong to the CLASS Magnoliopsida, SUPERORDER: Caryophyllanae, ORDER: Caryophyllales, FAMILY: Nepenthaceae
Sarracenia belong to the CLASS: Magnoliatae (aka Magnoliopsida), SUPERORDER: Asteranae (name derived from the flowering plants known as asters) ORDER: Ericales.
In this regard, cephs are related to other cps -- if one goes back as far as the CLASS. However, in taxonomic terms, that is not a close relationship at all. (Consider that humans, mice, and whales are all members of the CLASS: Mammalia.)
