I recently made this offer to one LJ friend but I feel I should extend this offer to the general world at large -
I'm no botanist so I am not even sure I'd be much help however if my dreams are someday realized of having a gas chromatagraph mass spectrometer, I will be sure to test any and every thing you throw at me :D
