Dendrobium agathodaemonis is a tiny plant, only a couple of centimeters tall with a mat thin little stems, each with a few leaves, but it produces flowers that dwarf the plant, about three centimeters long and in this case a cherry red color. I have another clone that is pink with a white lip, but these flowers are completely red. The plant is blooming from seed for the first time.
Dendrobium agathodaemonis is closely related to Dendrobium cutherbertsonii and some consider it a variety of that species. There are obvious differences, though perhaps not enough to make it a species in its own right. The lip does not have the dark coloration of Dendrobium cuthbertsonii and the growths are thin and wiry rather than having distinct pseudobulbs.
