I stand to be corrected, but I think it is one fewer than the number
of leaves in the final tree.

I'm puzzled by the interaction.depth argument to the gbm() function, and
whether it specifies just the tree depth, or also (implicitly) the number of
distinct features used in splits.
From some version of the documentation I have:
interaction.depth The maximum depth of variable interactions.
