These plants were growing at a quota of 2600 ft. and photographed on the 28th.April 2013. Browsing through various books and the photographs of a couple of sites, I havn't been able to identify this plant. Hoping for help.
Thanks lila for coming to my aid. In a few minutes I am going to post a new thread. I could do with your help and that of Andrey. Best wishes, duffy
