Membrane systems with dividing and dissolving membranes
are known to solve PSPACE problems in polynomial time. However,
we give a P upperbound on an important restriction of such systems. In
particular we examine systems with dissolution, elementary division and
where each membrane initially has at most one child membrane. Even
though such systems may create exponentially many membranes, each
with dierent contents, we show that their power is upperbounded by P.
