What specific points should I ask my professors to include in my LOR?

I want to apply for a PhD in anthropology, and I spoke to some departments who said they want letters detailing how well the professors know me and my work. What else can I ask them to include aside from prior research, my interests, my ability to undertake grad work, etc?

Evidence of your maturity, professionalism, work ethic and self-motivation, using specific examples.
