    Just curious if anyone has noticed any plant morphological features that can help in deciding a plant whether its a male or female?
    Internode length? Way that side branches/shoots develop?, shape of pitcher?, [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/confused.gif[/img]
    Any keen eyes in this group?

    Hmmm, I reckon my female aristolochioides leans towards me when I enter the greenhouse, and my male lowii dunks me with water too often for my liking .... But seriously...

    Not that I have ever been able to pick. It would be great if there were, but they all look the same to me. I wonder if someone could produce any easy DNA sex test

    Do you know how much DNA sexing cost these days?!?!!?

    But maybe a kit like a pH kit that changes the water of sap in water to show gametes of either male or female. How do they test (before ultra sound and light waves) for the sex of an unborn child?

    From what I know, before ultrasounds, people didn't know the sex of their child was going to be till it was born. Not scientifically anyway. They do have old wives tales on how to tell what the baby is going to be. Heres a link on some of the ways to tell...

    There is no way to know what sex the plant is before it flowers (unless it has been used as a parent plant in other crosses such as our N. bicalcarata clone #38 'Big Mama'=female, N. wrigleyana= female, N. morganiana= female, etc...)

    After the flower spike begins to form you can tell the difference between male and female flowers. At least you have some time in advance to find the other sex. Besides, the sex doesn't really matter until it is in bloom.

    The female flowers are slightly elongated. Here is a pic of our female N. thorelii x densiflora developing flower spike:


    The male flowers are round. Here is a pic of N. 'Gentle' (male developing flower spike).

    Trent great photos.
    I sort of knew that from my plants, but was curious if anyone has noticed something like a sheath shape or maybe how the plant grows.

    One method I used to use was that if a plant made a lot of offsets, this was a great potential that this was a male plant where as a plant that doesn't produce much side pups or maybe just one side pup was a female plant. Anyone seen any of this (strange cases of did you notice or do you care?) besides me? For many of my plants this has worked, but perhaps just a lucky strike.

    Wow, I never noticed that! But now that you brought it up, I realized it is true! Good info.

    Anyway, for the offsets method, I dont THINK it would work...but if it does, you will need 2 plants of the same species and age in order to sex them, and how if both were the same sex!
