Bonaventure,

With the Lilium it produces a shoot that heads down to the desired depth
and then swells to form a small bulby thing. With the Scadoxus the shoot
comes from the seed in a similar way to things like Amaryllis belladonna
but the bulb forms right at the surface and never produces a leaf
initially.  For a while you have a small seed sitting on the surface with
an attachment to this growing green bulb next to it.  Slowly the seed
atrophies until there is nothing left of it. I would imagine that this is
just like what happens with the Arisaemas, it is just that with the
Arisaemas the bulb is produced at a depth instead of at ground level.

The only distance from the seed would be depth..... they don't shoot
laterally a distance before producing the bulb as this would be a waste o=f
valuable energy I'd imagine?


Cheers.
