Dendrobium agathodaemonis is considered by many to be a synonym of Dendrobium cuthbertsonii. To the untrained eye, however, there are obvious differences, though they may not warrant species status. Dend. agathodaemonis, though the flowers are of the same shape and size as Dendrobium cuthbertsonii, lacks the dark markings on the lip and has growths that are much thinner. Both of these features are obvious in the following photos. Like its near relative it is a prolific bloomer when grown well and has flowers that come in a rainbow of colors ( I have a red clone as well) and last many months.
