Mark, There is no rest for the mind, indeed: There were proposals for combining Aronia and Photinia years ago, but new molecular studies show, the two genera are not close relatives.
http://www.bergianska.se/pub/publikationer/Eriksson/Potter_et_al_2007_Rosaceae.pdf See figures 2-4 (pages 29-31): number of genera are closer to Aronia than to Photinia, and number of other genera are closer to Photinia than to Aronia. An another study: http://biology.umaine.edu/Amelanchier/Pyrinae_2007.pdf See figure 1 in page 128. This study arrives at a little bit different phylogeny but again Aronia is not close to Photinia. An interesting finding by these (and also other) studies is that Sorbus is not a monophyletic group, and consequently it is divided to five genera: Sorbus, Aria, Torminalis, Cormus and Chamaemespilus. - Kouta On 23 marras, 18:44, Mark Binder <[email protected]> wrote: > Hey Steve, I don't want to be the bringer of bad news, but, Aronia -at least > arbutifolia and melanocarpa- have been merged in to Photinia!
