    @jeff 2: I will have no spur picture for this year. The blooming is over. I think we will get confirmation with the DNA pretty soon now.

    Also, I really ponder about the resistance to the cold of this plant. I mean, the still water gets totally frozen over 2m of depth here during water. Thus, it means that the plant freezes hard every winter, thaw in April/May and keeps going for about 4 months before freezing again. When you think about it, this plant spends more time frozen than not. wow !
    this plant make turion ( small buds resting, in fact young foliage balls tightly clamped.)
    In winter, in situ, they descend to the bottom of the pond (Where there is open water) to return to spring on the surface .

    ex situ ,in winter , if in your tank you have no open water , They must be returned to shelter.

    I think we will get confirmation with the DNA pretty soon now.
    for me with a DNA ( genome) difficult to make a determination , but with a consensus tree by phylogenetic , yes .

    If I'm not mistaken, it's usually possible to ID a species using a "genetic barcode"--a gene that's unique for each species, but fairly homogenous within a species (usually a mitochondrial gene, I think). It's not terribly useful for phylogenies on its own, because for those you need multiple genes, but it's useful if all you want to do is ID to the species level.
