  We report the detection and localization of X-ray emitting ejecta in the
middle-aged Galactic supernova remnant Puppis A using five observations with
the Suzaku X-ray Imaging Spectrometer to survey the eastern and middle portions
of the remnant. A roughly 3' by 5', double-peaked region in the north center is
found to be highly enriched in Si and other elements relative to the rest of
the remnant. The X-ray fitted abundances are otherwise well below the solar
values. While the ejecta-enhanced regions show some variation of relative
element abundances, there is little evidence for a very strong enhancement of
one element over the others in the imaged portion of the remnant, except
possibly for a region of O and Ne enhancement in the remnant's south center.
There is no spatial correlation between the compact [O III] emitting ejecta
knots seen optically and the abundance enhancements seen in X-rays, although
they are located in the same vicinity. The map of fitted column density shows
strong variations across the remnant that echo earlier X-ray spectral hardness
maps. The ionization age (as fitted for single temperature models) is sharply
higher in a ridge behind the northeast-east boundary of the remnant, and is
probably related to the strong molecular cloud interaction along that boundary.
The temperature map, by comparison, shows relatively weak variations.
