EDIT: 3/9/2014 I now believe this to be Dendrobium calamiforme and I have changed the thread title accordingly. After reviewing Marni's post from 2009 ( http://www.orchidsforum.com/threads/dockrillia-teretifolia.909/ ) I should be embarrassed to post my plant, but here it is anyway. Grown bright, mounted, intermediate. I reduce the water in the winter but don't give it a dry rest. This plant struggled for a few years until I found its niche but is doing fine now. There appear to be at least 3 more spikes starting.
