Pansear evolves by Fire Stone into Simisear.
it is in the desert near relic castle
Petilil will evolve with a sun stone, pansage with a leaf stone, panpour with a water stone, and pansear will evolve with a fire stone.
Pansear uses a fire stone to evolve into Simisear.
Castelia city just as you go into it after the bridge from Pinwheel Forest
So far (although I have completed White not yet Black) all I know are Pansage (Leaf Stone), Pansear (Fire Stone) and Panpour (Water Stone). Sorry if this isn't as helpful as you hoped!
