Pencil Tree

[Martin]

I recently recieved a clipping of what I only know as a Pencil Tree.  It is
a very cool tree, and I am currently trying to root it.  I have looked
everywhere and can find no one who has heard of it.  If you know anything
about this plant, or how I could find out about it, please contact  me.
Thanks,
