Dear Friends,

Well said, Michael---any confusion that might have existed concerning the 
'correct'  Philo. species on which to place this name was cleared up by Dr. 
Eduardo Gonclaves' EXCELLENT article and scientific description of this 
wonderful plant as a 'good' species'. The article  featured both photos AND 
fantastic line-drawings of this extremely now-rare-in-the wild plant, less 
than 20 specimens are known to exist in the wild, all isolated from each 
other on remanant  trees left over from forest clearing and now standing  in 
cattle pastures, no pollenators, hence so sexual reproduction is taking 
The one question I have is how many independent collcections were originally 
made, and if there was variability in say leaf-shape or color to these 
different collections that were all presumably the same species, and to say 
that perhaps someone could start a discussion-group where photos could be 
posted of individually-owned plants of this species, we could then confirm 
if a particular plant is indeed this species.
I once more make a call to those in the USA who may be fortunate enough to 
own a plant or plants of this species to make every effort to hand-pollinate 
it and so get some seed w/ some genitic var., the same urgent request  is 
now made to aroid loves in its native Brazil, Dr. Eduardo Goncalves and 
others,  please try to hand-pollinate a couple of  wild blooming plants to 
obtain seeds, without this effort NOW,  this wonderful species is doomed to 
extinction.   Perhaps we could once more discuss some limited tissue-culture 
of the remaining plants.
Julius Boos,

Without the natural pollinators, even hand pollination is only a stopgap.  Did anyone ever observe the pollinator before the habitat was destroyed?  I don't suppose there are any living, captive stock of it?  If so, that would be one of our first conservation measures.  If the elements of the species' natural history can be reassembled, there may be hope of one day re-establishing wild populations, whether by restoration of the original site, or construction of a new one; but without these interrelationships, it will become extinct in the wild, perpetuated only in cultivation.
