I don`t believe that you have been following in detail the long-winded
discussion of the use (and missuse!!) of the COMPLETELY useless name,
Philodendron "Santa Leopoldina' which was and is being bantered about and
added on to, or in some cases in place of, the correct scientific name for
ONE of the plants it has been associated with, namely Philodendron
I believe that what Eduardo is saying, tongue-in-cheek, is that one can NOT
extract DNA or identify a 'horticultural legend' (Philodendron "Santa
Leopoldina"), root-tip, leaf or otherwise, as today no one knows what this
plant was or is!
People, PLEASE---DROP this name!!
However, I am certain that Eduardo will be sucessful with extracting the DNA
from the scientifically described and easily identified plant he is working
with, namely Philodendron spiritus-sancti.
What do you mean you can't take a DNA sample of Kautsky's plant?
Does one have to use leaves for DNA? Could one not simply collect a
root tip to get DNA?

Dear Tom, Eduardo, Pete, Alistair, Wilbert, etc.,
I think it fitting that on behalf of all the members of aroid-l, that we
just say a simple word of thanks to all the professionals, a few of whom
have mentioned above (forgive me those of you who I have not mentioned!)
take time from their busy lives and professional duties to share some of
their hard-learned knowledge with us who do this 'plant thing' just as
I can only hope that all of us 'out there' recognize what a valuable
resource aroid-l provides to all of us who seek information on this
plants we so love, to have persons of this caliber literally at our
fingertips to respond where possible to our questions!
Thanks again, friends.
We visited Robert Kautsky, the original collector of the
type of P. spiritus-sancti. He gave the plant George Bunting described.
observed the cultivated specimen he still keeps on his farm (from which
specimens were prepared) and we spotted similar material around. We have
been collecting in Espirito Santo state for years and we could only
this species in Kautsky's farm. Obviously we used classic taxonomic
characters to ID it, including sections on flowers. That was not that
because there is no other species that could be REALLY confused with P.
spiritus-sancti, although you can confuse many species under the popular
"loose" definition of "Santa Leopoldina". Right now we are using clones
the type specimen to make a profile based on the "DNA barcode" concept,
order to make identifications of P. spiritus-sancti more reliable.
Unfortunately, the "real" identity of P. "Santa Leopoldina" will be hard
find out, mainly because you can't extract DNA from an horticultural

OK. So how reliable are the reports of the remaining P. spiritu-sancti
the wild? What distinguishing marks should we be looking for? I have
looking at the pictures in the postings and they vary quite a bit. How
I know a real one when I see it? On what basis do the searchers in
make their determinations? Maybe the only plants left are examples of
or another of the sham plants.
