G'day CPUK,
here's another update from U.humboldtii vs. H. folliculara.
First of all, many thanks to James O'Neill for helping to determine the microorganisms. And for Mobile for the tip of
David Attenborough. These reports, I already knew.
In the meantime, I've made contact with Stewart McPherson. And he told me, that he has in his expeditions to the Tepuis in different species of Heliamphora observed Utricularia humboldtii in their pitchers.
Following now the latest photo of the growth progress.
Finally, thank you, Stewart McPherson.
Greetings
Richard
