I do not know of any such case in _Utricularia_. Such a species is
assumedly not in cultivation. Only few species of _U._ are restricted to
one or few mountains but all of which were either recently confirmed to
still exist where they belong or not seen for a while because nobody
managed to access their remote homes. Where should the species you
mentioned have come from? Most rare species of _Utricularia_ are threatened
by the various enterprises by _Homo sapiens_.
