Mark, I can say only that I have difficulties to find one single reference which supports the splitting Cornus. Cornus is recognized in the broad sense in the taxonomic databases I mentioned above (GRIN and NCBI), in Heywood et al. (2007): "Flowering Plant Families of the World" and also in the Angiosperm Phylogeny Website which is usually a very good general source about the angiosperm taxonomy/phylogeny:
http://www.mobot.org/mobot/research/APweb/orders/cornalesweb.htm#Cornales Some references supporting the split are mentioned here (first seems to be in 1942): http://www4.ncsu.edu/~qyxiang/Cornus.new/tax.history.html - Kouta On Nov 24, 3:50 pm, Mark Binder <[email protected]> wrote: > 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 -- Eastern Native Tree Society http://www.nativetreesociety.org Send email to [email protected] Visit this group at http://groups.google.com/group/entstrees?hl=en To unsubscribe send email to [email protected]
