    Henry, thanks for the respective explanations. What a muddles mess this whole area is! In light of all that, it makes me wonder why some fuss over location data?

    Well, different locations can still have different genes, even with gene flow, if there's natural selection acting on those genes. Ergo, even if they're all the same species, some regions may have brighter colors, larger traps, etc.

    The populations can also be adapted to local conditions for example Drosera intermedia "Cuba" and Drosera anglica "Hawaii".

    Two reasons:

    1) Conservation initiatives, like NASC; and,
    2) Some people are crazy about collecting.

    I agree with #2, but in light of what we know about how things change, is it really important, in the larger picture?

    Actually, it can be; there are numerous fossil examples (mostly in snails and clams, because the preserve so well) when a particular adaptation has arisen in a sub-population then spread throughout the whole population or species.

    A vital part of a species long-term survival is preserving the genetic variability it needs to evolve in the face of new challenges, and preserving regional varieties preserves this natural variation.

    Humans go to great lengths to preserve aesthetically pleasing genetic characteristics, which often end up in inbreeding and unhealthy animals and plants. I've seen that with chickens, tropical fish and goldfish. They are susceptible to anything that comes along and wipes them out. I think the emphasis should be more with the variation, rather than preserving certain characteristics.
