From JOY: Chipotle (dried smoked jalapenos) come in two different types both made from different cultivars of the jalapeno. First is a black -red chili chipotle (also known as the colorado,mora, or morita) Second is chipotle meco which is larger (3-4 inches long by an inch wide)
I see the first one more than the second, and would also recommend it.
