The optical emission lines of N49, observed at very high angular and spectral resolutions, show that this supernova remnant evolves in a cloudy, heterogeneous interstellar medium. Measured line-of-sight velocity dispersions of individual line profiles range from 5 to 130 km s-1. The smaller velocity dispersions of 5 - 15 km s-1 are associated with a photoionized shell that is at rest with respect to the LMC. The larger velocity dispersions of 30 - 130 km s-1 are associated with smaller, shock-ionized regions that form a spherically expanding system in the shell's rest frame. The projected expansion velocities, as large as 280 km s-1, indicate that N49 is at most 16×103yr old.
