|Wow, great info Julius! Yeah, the fact that these aroids depend on non-existent pollinators certainly puts a damper on feral colonies escaping into the suburban landscape, although it would be cool to see Philos like this climbing the occassional building, to the horror of its occupants...|

[Aroid-l] Origins of Philodendron x evansii
Good to see you on aroid-l again!
I`m certain that Ron Weeks, Russ Hammer, ESPECIALLY John Banta, and Steve Lucas
may be able to add information about the history of this Meconostigma
Philodendron hybrid, and of Mr. Bill Evans, it`s creator. We have had several
discussions about this Philo. hybrid.
It is surmised that Mr. Evans may have used P. bipinnatifidium crossed to P.
speciosum as the parents of P. x evansii, but this is not known for certain, it
may have been P. mello-barettoanum instead of P. bipinnatifidium. We also do
not know which species was used as the seed parent, and which one as the pollen
parent. Also bear in mind that what is presently being called P. speciosum
just may eventually be determined to consist of several distinct species, as
the plants being called P. speciosum certainly present a broad range of sizes
leaf blade shapes! (to me that is!) We do not know which one (if any) of
these were used by Mr. Evans.
What I can add is that no species of Philodendron has established itself as a
feral plant (escaped from cultivation) as a self sustaining species, as the
pollinators (small scrab beetles) are not present, so sexual reproduction in
the U.S.A. is not known to take place except by hand pollination. There are
a few plants of climbing Philodendron sps. I sometimes see on a tree, most
appear to have originated from trash thrown out and which somehow survive and
climb and multiply vegetativly, but I have never seen a sizable colony of any
Philodendron sp. anywhere, and certainly no Meconostigmas. The closest to
this is a report I received of a large group of a smaller Meconostigma hybrid
which might be a P. corcovadense X P. speciosum or P. paludicola cross. This
large group of plants, all from vegetative
divisions, was reportedly covering
the base of a BIG Cypress tree in W. Florida. I have a plant from this
colony, and it likes to scramle and climb (like P. corcovadense),
and produces off-shoots quite readly. A friend also told me of a no-longer
existing ''hedge'' in the S. Miami area which consisted of a
smaller Meconostigma Philodendron which was seemingly close to this one.
Syngonium podophyllum (and possibly other species of Syngonium) have become
established as a reproducing feral and invasive pest aroid species in S.
Florida, the pollinators of this are PROBABLY fruit flies, and I have collected
viable fruit and seed in a lot of areas of S. Florida, and the juicy fruit and
large black seeds are probably distributed by native birds.
Colocasia sp. and Xanthosoma sp. can be seen as invasive, VERY abundant plants
in many areas of Florida, Colocasia more so than Xanthosoma. These colonies
are all from
vegetative reproduction/spread. All probably originated from
discarded food leftovers consisting of peelings thrown out as trash, or plants
put out by homeowners. No sexual reproduction/seed production has not been
observed in these two genera, though blooms have been observed on both, which
might result in seed production at some point.
Large feral plants/colonies of Xanthosoma robustum (6'-8'+) might be
mistaked for P. x evansii??
>> Hi all,
> I am reorganizing the meconostigma site so it has more articles (in
english similar to the leafcutter ant site i maintain, because my malay is not
deep enough to write very well in that language), and am hoping to put together
a post in the meconostigma site about the origins of P. x evansii.

the major historical figures in Disney history.

which i doubt, but you never know.
