    Well, N. X 'Ventrata' usually has a wider peristome than plain N. Alata. Ventrata is also usually more colorful in lower light than Alata.

    Hi Cindy,
    The same question we all asking in Singapore.
    Make a little research; the following are my findings (open for correction):


    N. Ventricosa has smooth swollen pitchers, irregular peristome, wider mouth often with a narrowed 'waist' and the pitcher overall is shorter but wider than N. Alata.

    While N. Alata is typically bulbous in the lower half and cylindrical above, smaller mouth with a smoother peristome.

    N. Ventrata takes on a mix of both parentsí traits:
    From Ventricpsa; irregular peristome and slight wider mount than Alata.
    From Alata; pitcher length and bulbous in the lower half and slightly cylindrical above.

    Please discuss

    Hi Jalan Kayu, thanks for the phone call yesterday.
    The nepenthes labelled N. alata from Island nursery, the one you and I bought, was confirmed to be N. ventrata by Tony Paroubek in the identify that plant forum I posted on 27th June.
    I quote from Tony < " Hi Neil,
    I would start off with the N. alata pictured on that link. This appears to be N. xVentrata. >"
    Which is what you've believed all along.
    As for the number of pitchers, yesterday I was wrong when I said 20. I counted it yesterday evening and there were 39!!
    Best wishes and happy growing, Neil.
    A &#39;pitcher gallery&#39; is where the art is drawn by Mother Nature and a &#39;pitcher says a thousand words&#39;.
    My pitcher gallery is at: http://community.webshots.com/user/neilsingapore

    Keep an eye on the peristome. N. xVentrata will show some of the pointy spots along the outer edge like N. ventricosa while N. alata doesn't. Leaf structure is also useful. N. ventricosa looks like one tapered leaf with the leaf edge going all the way down to the stem and wrapping around. N. alata has a clear petiole.

    Is that a Nepenthes in your pocket or you just happy to see me?
