Most specimens of _U.quelchii_ have scarlet red flowers. I have seen
pictures of almost orange flowers. So there may be some variation in flower
colour.

Is there any other difference (in your plant) besides size and flower colour?
You should examine "leaf" size and texture, number of scales on scape,
shape of bracts and bracteoles, pollen colour, seed shape, etc.

The only other known species of _Utricularia_ related and similar to
_U.quelchii_ is _U.campbelliana_ (said to be a more delicate plant,
differing in the number of scales on the peduncle and the width of bracts
and bracteoles).

However, if the differences you mentioned were found in several
geographically separated populations, and especially if they are
non-overlapping (with _U.quelchii_ s.str.) and constant even in
cultivation, your plant could perhaps be considered a new species
(_U.asplundii_ is also not very much more than a large _U.jamesoniana_). Do
you have living specimens of the plant? Do in any case not forget to
preserve specimens (preferably in liquid) of it, so it may eventually be
described validly!

Kind regards
