Yes, thank you Kouta, the mind does continue to spin, Interesting articles. I do notice that Photinia's placement is still a little isolated in relation to others in its clade, and that the fruit character does distance it from Aronia. I'm wondering what your thoughts are about the fracturing of the genus Cornus. Mark

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!
