If you can help ID these plants please contact the owner at the email address shown after the pictures
All those pictures were taken on the Inca trail near Machu Picchu at an altitude between 9000 and 13000 ft (2700 to 3900 m)
Most were growing terrestrially or as lithophytes
Any help of identifying these species will be appreciated .
Except for one whixh is clearly an Oncidium and one that is a Maxillaria I think the rest are Epidendrums.
If you can help with the ID of the above plants please contact Ed at "firstname.lastname@example.org" . Thanks, Ed
