I once inquired, preceding a trip to Chile, what aroids I might find
there.  I was told none, though there were plenty in various yards and
gardens around Santiago.  I understand that this is one aroid which lives
very close, on the Argentinian side of the Andes (where I understand one
might find Gorgonidium vermicidum also) near Salta.  This is the next
town from our site for the ALMA telescope array on the Jama road over
the Andes from Calama, Chile; sites near Salta were proposed also, being
touted as very dry.  Higher is best, so the site was chosen at Chajnantor
near San Pedro de Atacama.  If the weather in Salta is similar to that
at Chajnantor, the southern summer, sometimes called the 'Bolivian winter'
or more politically correctly the 'altiplanic winter' is the wet season.
During this period the wind shifts from a constant westerly flow over the
Atacama desert to an occasioal easterly flow up from the Amazon basin
bringing moisture to the peaks (and snowfall to Chajnantor, where there was
a several inch accumulation last week).

I'm not sure how much the weather at Chajnantor applies to Salta, but
we operate extensive weather monitoring equipment there, the data from which
may be examined at http://www.tuc.nrao.edu/mma/sites/sites.html
including photos etc.

I would be interested sometime in taking a field trip and hiking around Salta.
If anyone knows how common these aroids are or what sort of microclimate
they enjoy, I would like to hear about that also.  There are descriptions
on page 164 in The Genera of Araceae by Mayo, Bogner and Boyce, with color 
photos of the flowers in Plate 115.  The local climate is indeed described
as thorn country.
