Individual seed will often germinate much later than others in the same flask or compost . . .
    Thank you very much for the help. I will definitely wait on them. Thanks again!

    Here is another round of seed, getting ready for aseptic germination -- just a few short hours from a FEDEX envelope (a standing project for a good friend of mine with little time on her hands -- something having to do with the care of two teenage girls) . . .

    Good luck BigBella! I hope you get good germination rates from the seed.

    Jeez you just have seeds of everything! When you get AW's Doorman's top 1 and pitopangii into culture, can I have one of each?

    Here is a vial with a single seedling from this morning, in some experimental media I have made for Nepenthes -- particularly low in ammonium compounds (both nitrates and chlorides), to which they are very sensitive. A full strength batch of Muroshige and Skoog (MS) media, for example, has something on the order of 1650 mg/L of ammonium nitrate; whereas, the mix currently being used has less than ten percent of that amount.

    The first true leaves are just developing as the cotyledons begin to darken . . .

    Here is an update on one of the highland Nepenthes species illustrated at the beginning of this post; and I am still getting new germination almost six months out. The most successful seed batches to date were kept under highland conditions from the very start: relatively warm days (as high as 24˚ C) and cold nights (as low as 10˚ C) . . .
