Hi Joanna,
Tell me if you agree with this, or if you have seen a clear exception to
this "rule":
Spikes form on the trunk in a position parallel to the leaves on one
side or the other. A new growth in that position can still be either
spike or root but something new growing in a different position around
the trunk has to be a root.
