    Gus, izumiae, like quite a few other Sumatran species from the same area like jacquelineae, aristolochioides, bongso and inermis, are found on 2, 3 or more mountains, so there are slight differences between the areas within some of these species.

    Hi Hamish: thanks for the info. The reason behind my argument is that both of these plants are from the same mountain gunung talakmau, as far as i know.

    Gus, given they're both from Talakmau, and not from Lusung Tungkut or another location, you wouldn't know without field observations whether there is consistent different populations, or whether there is another factor involved such as hybridisation. It's always highly possible that there is some differentiation with a small population, even in a very restriction geographical range. I'll have a word with someone who collected seed from those mountains the year before last to see whether he has photos which may give clues.

    Hi Hamish:

    Yes, I agree that without field observations, nothing is certain. I still tend to believe that the "hooded izumiae" is in fact a variant of the other species, definitely not a hybrid since this plant has been examined thoroughly by Dr. Clarke himself.

    The hooded izumiae is very interesting as far as i know, no other species have such a hood-shaped lid with a distinctive groove in the middle. Hybrids don't usually show unique characteristics.

    Hi Nong and all:

    nice plant you've got there. I like the word "wok" for the lid.
    do you have photos of the leaves, upper pitchers or is that an upper?

    I am sure there are other species with the wok shaped lid, but there are not many i can think of.
