The Potentilla breweri complex (Rosaceae) has been giving systematists headaches since at least 1940, and introducing molecular data has not especially smoothed out the problems. This group’s rampant putative hybridization, geographically fragmented distribution, and bizarre karyology are well reflected in our GBS results — that is to say, despite analysis with several different phylogenetic approaches, the resulting trees fail to make very much sense at all. Even so, though, patterns do begin to emerge. We will discuss the interpretation of the most interesting morphological, cytological, and biogeographic themes that appear in our work so far, with an eye to future inference from larger (but probably equally odd) datasets still being developed.
