During Passover, what are some distinctions of what is and is not Kosher?

Typically, there are two main branches of Judaism based on geography. Ashkenazy, predominately from Europe, and Sephardic, non-European. Overall grain is prohibited and many other items they may be unholy for the 8 day period. However, within the Sephardic tradition, certain allowances are made that are not observed by Ashkenazy, such as beans and corn. In some practices, dependent on the degree of religious practice, the observant will share the tradition of the community in which they reside rather than the geographical definition.
