    I've been looking at pictures of N.hamata and I'm wondering if there are different forms of this species, take a look at these two pictures:


    picture from www.plantarara.com


    picture from www.wistuba.com

    Are these genetic differences, upper pitcher vs. lower pitcher or response to growing conditions?

    Hi Vagabond,

    George hit the nail dead center. The first picture however is the red flush of an N. hamata. It has a red peristome rather than the brownish-purple. I have the black peristome variety but my light is low and the peristomes and pitchers aren't nearly as colorful as they should be. Anyhow here's a picture of a newly opened pitcher. Pitcher is a few days old.

    There seems to be some variation in color of the pitchers. It does take a week or so for them to color up and growing conditions will affect it somewhat. Also small plants (pitchers a couple inches or smaller) look alot more similar and don't always have fully developed coloration and markings.

    The first picture is one that I call red flush. As it gets larger and is grown under good light the color between the red veins fills in. Much different than the typical dark spotted ones. These types can vary also with the base pitcher color varying from green to light purple.


    You can see the younger pitchers only displaying the red veining in the background.

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

    It does get a little more purplish as it ages. But it seems to retain that suffused look rather than the distinct spotting seen in the other pictures. It also does need to be a decent sized plant before it really starts to show it's stuff. Not sure how it would respond to underlights growers either as far as coloring up.

    I guess I'll have to join in the fun too! I guess I've got a got a "purple" variety from Tony. I like the almost black peristome! Nep hamta is my favorite cos it's got those stiff wiry hairs and teeth.

    Heres the pitcher which formed in January (the peristome is almost expanded). The pitcher is 3 3/4" tall.


    Here is the whole plant in a plastic net pot the pot is about 9" across


    Once it settled in it's growing pretty quickly (all the pitchers you see are ones made since it arrived to me in June or so). The original pitchers dried up very fast due to my lack of adequte humidity (now my tank is filled with a dense white fog from the humidifier most of the time). I'm very anxious to see the large pitchers on my plant.

    It's a great highlander if you can replicate the environment of very humid (this guy will snap his lids shut within hours if it doesn't have the humidty it wants and within a few days you will loose the pitcher altogether) and cool nights, cool days doen't hurt either as most of my highlanders are doing better in winter with the cooler days which are never more than 75*F
    whereas august daytime temps can hit 85*F.

    Hmm interesting information here, I personally prefer the red flush but even the typical one looks very nice. I'm putting together a highland terrarium to start into gorwing highland neps again and I think I'll add this species to the list of prospective tenants.

    Swords, I've heard that its very sensitive to humidity changes, apparently the leaves are quite thin and loose moisture very quickly?
