R. J. Taylor, when he collected this plant, needed a name for it to differentiate it from the rest of the Echeveria affins he was finding, because it looked so much different. However, he couldn't name it an entirely different species because, although it was different from E. affinis, it wasn't different enough to justify a brand new species name. Therefore, for some reason, he decided on attaching the cultivar name "Black Knight" that we know despite the norm being to create a form like was done for Haworthia retusa to make Haworthia retusa f. geraldii when the latter differed slightly from the former.
Why he picked that particular cultivar name, we'll never know, and many people don't think we should even attach the name 'Black Knight' to the plant. They think it should just be called E. affinis. However, we use it because it is known generally by people as Echeveria affinis 'Black Knight'.
