The genus Spathiphyllum appears to be monophyletic (e.g. one origin) even if it presents actually =C2=A0a disjunct distribution.
Also Holochlamys seems to be included within Spathiphyllum and not a sister genus!

An interesting question. If you are speaking of potential fossil record and the like, I haven=E2=80=99t a clue. However, plants were being collected that would later be included in Spathiphyllum back in the mid-1800=E2=80=99s. Interesting also that this genus has several Old World representatives in Southeastern Asia =E2=80=93 at least listed in such a way as to make one thing that there are some species native to the Phillipines and Solomon Islands, and that it is not strictly a Neotropical genus. But it seems that with relatively little pushing you could have arrived at this same information, so this may not be what you=E2=80=99re looking for at all. However, this answer may cause someone to respond, simply because they want to demonstrate that they know more, and that might provide you with a closer answer to your query. Hopefully it will be shared in this venue. Good Growing!
Would anyone have any information about the age of the genus Spathiphyllum?
Thank you very much.
