Is cayenne pepper the same as capsicum?

Cayenne pepper and capsicum are not the same, but they are related. Capsicum refers to the genus of plants that includes various types of peppers, including bell peppers, jalapeños, and cayenne. Cayenne pepper specifically refers to the dried and ground fruit of the Capsicum annuum species, known for its heat and flavor. So while cayenne is a type of capsicum, not all capsicum are cayenne peppers.
