Ok. I will do some more research and re-evaluate later. When Owen reported the D. punctata in October, I noticed a lot of the D. dendrobioides that had been reported looked like they could actually be D. punctata, so I might need to double check them.
Yellow callus notwithstanding, these look like D dendrobioides to me. Some dendrobioides appear to have a yellowish callus although it doesn't appear as strong as in punctata. Otherwise seems to fit though?
