Today I came across this very interesting quote in Deni Bown's
excellent book Aroids, Plants of the Arum Family. On page
219 Deni writes: "In addition to these species, many elephant's ears in
cultivation come under the name Philodendron domesticum (synonym P.
hastatum). No one seems to know where this species came from
either". The assertion Philodendron domesticum was formerly
known as Philodendron hastatum is then repeated on page
Personally, I would not consider P. hastatum an
"elephant's ear". Numerous websites, including the USDA, now assert P.
hastatum is a synonym of P. domesticum. It appears the
belief Philodendron hastatum is now known as Philodendron
domesticum may have originated from this text. Philodendron
hastatum was identified 112 years before Philodendron
domesticum. All photos on the internet described as Philodendron
domesticum do not even look like Philodendron hastatum (P.
hastatum has distinctive blue green leaf blades). No official
database I can locate has a photo of P. domesticum. I have also
tracked down other names (i.e. Philodendron elongatum, Philodendron
hastifolium) that are stated on botanical sites to be synonyms of
Philodendron hastatum. I am trying to get to the source of this
belief and if it is even possible it is factual the older name has
been replaced with a much newer name. According to numerous
emails exchanged with Dr. Croat and a few with Dr. Eduardo Gonçalves we know
exactly where P. hastatum originated: Brazil. Philodendron
elongatum appears to be a variant of P. hastatum and one source
says that plant originates from Guiana.
I can find nothing on TROPICOS, ePIC, IPNI, or other databases
to verify the belief the name has been changed. Dr. Croat's logic appears
distinctly to the contrary. Despite checking every available database I
cannot find where P. domesticum originated. Does anyone have
contact with Deni Brown and, if possible, can we gather a clarification as
to where this belief Philodendron hastatum is now Philodendron
