Incompressible magnetohydrodynamic turbulence is considered in a geometry in which the fields are all independent of the z coordinate, e.g., but have all three components. This is a limit frequently called ''two-and-a-half-dimensional.'' It is conjectured that simultaneous inverse cascades of magnetic helicity and mean square z-component of vector potential may exist. At high Reynolds numbers, selective decays to states of finite pressure gradients appear to be possible. Anti-dynamo theorems are difficult to prove for this geometry.
