    I'm having trouble imagining what this plant will ultimately look like, or if I've seen it before. Right now, the leaves look like a pinwheel with tendrils at the ends, and there's a jack-in-the-pulpit shaped flower about to open (or maybe that's open). I neglected to get size info - maybe 50cm tall, leaves 12cm? I'm not at all sure of my memory on this. Are they even leaves or leaflets I'm looking at?

    There were two of these, and I think the other did not even have leaves open, on the south side of the main path in the Asian Garden.

    It is an Arisaema sp.
    Possibly Arisaema consanguineum.

    Agree, and what you're looking at are leaflets. The entire structure supported by the petiole is the leaf.

    I should have said that your pic 2 is it! That is as good as it gets.
    The wonderful single leaf is divided into 12 or so leaflets that end with long fine points.
    The flowering structure of the spathe/ spadix also shows in your pic
    They can sometimes get tall to 6ft. Ours just get to about 3.5ft
    I find them all Arisaema fascinating.

    This one-leafed Arisaema consanguineum on the main path at UBCBG still looks the same, but today I got to see the developing fruit. I wasn't originally sure if it was coming or going, but I read that they're supposed to turn red, so coming. A photo I found shows seeds ranging from green to red, and all a similar size, so I'm assuming all those little seeds will expand to be like the larger ones.

    Not necessarily all of them - it will depend on the thoroughness of the pollination for that spadix.

    Oh, so maybe this is it. Now I wonder if they'll all turn red. I'll have to go out there more often and remember to look, since we don't seem to have any Arisaema scouts.
