Not knowing a funicle from a furuncle, I would have to opt for Wilbert's
explanation of the feature found in Roy's seed which he thought might be a
developing radicle, even as the seed was coming off the seedhead.

It seems totally out of character for any seed to start germinating before
being shed, and there doesn't seem to be much question that the Arisaema
berry contains a germination inhibitor, which should at least be effective
until the seed comes out of the berry.

I suppose someone will discount my sweeping generalization  by citing some
kind of plant that sheds seeds that have started to germinate, but I'll be
happy to be enlightened.
