  We search for a charged partner of the X(3872) in the decay B --> X- K, X-
--> J/psi pi- pi0, using 234 million BBbar events collected at the Y(4S)
resonance with the BaBar detector at the PEP-II e+e- asymmetric-energy storage
ring. The resulting product branching fraction upper limits are BR(B0 --> X-
K+, X- --> J/psi pi- pi0) < 5.4 x 10(-6) and BR(B- --> X- K0bar,X- --> J/psi
pi- pi0) < 22 x 10(-6) at the 90% confidence level.
