SITF has determined this plant to be Aerangis spiculata, not A. modesta (Dec 2025). The key in the Field Guide to Orchids of Madagascar keys this to either A. articulata or A. spiculata. The spur of A. modesta is no more than 8cm and the spur on this plant is at least 14 or 15cm. According to the key, If the inflorescence opens from the apex first, it would be spiculata, otherwise it would be A. articulata. The exhibitor confirmed that it bloomed from the distal (apical) end of the inflorescence and moved up (pendent) to the basal (attached) end; technically blooming basipetally. (moving or developing from the apex toward the base). Also, the nectary length (spur) is consistent with A. spiculata.
