Here's a wider view of ox-eyes, and and explanation of DYC. Damned and yellow are self evident. But composite? I suspect you have to have been around as long as Sam and I for that one. Now days, it would be DYA. Damned yellow aster. The aster family (Asteraceae) was once the composite family(Compositae). Modern more exacting rules have brought a lot of changes. Whatever the generation, DYCs are fun.
