Wood type help

Submitted to Community Café

These are my hideous cabinets!  They're in my kitchen, living room, bathrooms, and laundry room. I was wondering if anyone can tell what type of wood they are?  They're stained darker than what the pictures look like. One set in the hall bath are painted, but the rest are all like this. I'm not sure what I'm going to do with them, but I am curious to know the type of wood.
