Of course, some of the beans in the photo look very similar to other. Judging by appearance, only about 33 of the 42 culitivars look distinctly different. For example #5 looks very much like number 22. Number 6 looks very much like #18. #15 and #38.
Does that mean of the 7,359 cultivars, only 5,782 are really distinctly different from each other?
