Hi Dave!
My name is Marcello, not Marco :)))))
I think you can get a good idea of the thorelii problem as it is at
the moment (Your plants, Tom's plants, the Nong's "tigers" etc)
reading the page on my nepenthesofthailand.com about "Trat", in
the "centre" map. There I explain some personal thoughts about what
seems to be the situation with the 3-4 plants that could be
considered N. thorelii.
N. globosa has nothing to do with N. thorelii or N. smilesii, but it
has to do with N. mirabilis. That's sure. Plus, in Thailand there
seems to be more than the 2-3 species we know. And all the new,
undescribed species that we now start to discover seem to derive
from these two ancestors: mirabilis and smilesii/thorelii (sanguinea
from the extreme south of Thailand being an even older ancestor of
smilesii/thorelii??).
The whole problem you say about the herbarium sheet of N.
mirabilis/anamensis is, as you say, what I explain in my site's
chapter "a long research", repeating Cheek's "theory", which
actually I consider to be only true one. If you read my "smilesii
chronology", that makes things even easier.
Oh, I just checked Tom's photos of "Thorelii Trat". Yes, that's not
smilesii, but as you read in my "Trat" page, we could still being in
front of two similar species (are they two forms of N. thorelii?):
the thorelii I found in Trat (0 m), Ko Chang (400 m) and Bangkok
herbariums (with the note "nothorelii" on the sheet) are in fact
different from the thorelii I found on Pha Taem (200 m) and from
Tom's Trat thorelii (which comes from a different location in Trat).
And by the way, my Trat/Ko Chang plants are really similar to Nong's
tigers, while the other two are more similar to Nong's Cambodia
thorelii/Dave's plants. But yes, maybe they're all true thorelii and
maybe just growing in different conditions (I still have strong
doubts about that...): it's strange how Tom's plants have wide
leaves in cultivation (probably lack of light? but the plants I saw
in the wild were often growing in shade!) and long linear leaves in
the dry specimens (and in the natural habitat).
Tom, you seemed to have disappeared for months!! Please write me
about yor thorelii findings in Trat and other places !! :)
In the mean time, please all of you make all the efforts you can to
give some of your plants/seedlings to worldwide distribution
nurseries, as while we talk these plants are disappearing quite
fast. In some cases just 5-15 plants were surviving in the locations
I visited. Because of rice paddies or new buildings, not because of
the 1-2 illegal poachers, but anyway...
