SITF confirms this plant is Dendrobium luzonense (Apr 2023). This plant is a good match in both form and color and the distinctive markings on the lip and column on an otherwise concolor flower; plant and flower measurements closely fit the description; plant is an excellent match to the original detailed description and drawing of D. luzonense in the Taiwania Journal published in 2007; good supporting photos may be found in several sources, including the IOSPE and OW; flower color is somewhat variable.
