Hi Ivan!

    Very interesting your theory, but sorry I am not so convinced yet...
:-)
    I agree about the absortive cotyledons of Drosera and Dionaea. It
hapens in Drosophyllum and Aldrovanda as well, as I have noticed in my
recent investigations. Thus, the seedlings retain usually one of the
cotyledons inside of the sead coat, producing enzymes to degrade the
nutrients (starch, in this case) and so absorbing them. It is noticed
when we note the cotyledon cells with huge nucleus, this way indicating
the high metabolic activity. I have some photos taken using microscope,
I can send some if you are interested.
    You say about some "nubs" at the cotyledon tips. In my study, I
could not see this one. Did you observe yourself or you saw in any
paper?

Best regards

Vitor.
