  Name that plant
From: Lester Kallus <lkallus at earthlink.net> on 1997.06.13 at 13:14:40(841)
I recall seeing a syngonium a few years ago that had variegated leaves and
a tip that curved up creating a little cup. Could someone please name it
and let me know if it's the type of plant that could survive easily indoors
during our Long Island winters?

Les,
You might be getting your genera mixed up... Check Exotica for Xanthosoma
atrovirens albo-marginatum.. Surviving indoors... depends on how warm you
keep your house and how much light... Needs warmth and lots of light...

Dear Julius, Les and Dewey,

Based on Les' description it seems to be a specimen of the
unmistakable Xanthosoma atrovirens Koch var. appendiculatum Engler, called
"tambataja" by the Brazilian natives. It is a Brazilian subspecies of the
"standard" X. atrovirens from Venezuela and adjacent areas (possibly the
yellow fleshed Xanthosoma quoted by Julius). Whereas the
Venezuelan subspecies has "normal" sagittate leaves, the Brazilian plants
have somewhat degenerated leaves, with white portions, appendices in the
end of the nerves and cup-like structures in the blade's apex. In
horticulture, there are a miriad of other names, like: X. atrovirens var.
monstruosum and X. atrovirens var. albo-marginatum, but as far as I know,
the only botanicaly correct name of it is that I already cited. It inhabit
northern Brazil, in the state of Para and I think I should say that
such state is one of the wettest and hottest of Brazil so don't let the
conditions go too cold, too dry or too dark.

Good luck (you'll need some ;-)),

Eduardo.

Quandry.... Eduardo.. I have both... or at least I thought I had both X.
atrovierens var. appendiculatum and X. atrovirens var. albo-marginatum....

Now, the quandry... the ....appendic.. has, under the leaf an appendage
that grows along the midrib... and is completely green... all of the leaf
and appendage... now, the albo-marginatum that I have is variegaged and
the base of the leaf has grown together to form a small cup... which forms
on the top of the leaf

I might like to disagree with you on what Les has... of course, based on
the above and what I have been told....

Dear Dewey,

Your observation is quite opportune and accurate, but I have some
interesting information about such plants. These names are very usefull
there overseas, since most material are clones of a few wild collected
plants, usually those with most odd characters. Here in Brazil (the center
of origin) we have some cultivated material that seems to be different
clones from yours and I have seen some rare plants with variegated leaves
(and with white margins) bearing the cited appendix, and completely green
plants with no appendix. Thus, probably the varietal taxonomy isn't that
easy. Now and then I'll listen such species more closely. I also think
that even if there is a true var. albo-marginatum, it is only a
horticultural name, not valid taxonomically speaking.

Best wishes,

Eduardo.
