Trisetella regia is, relatively speaking, the giant of the genus, and well-named regia or "regal." Most of the plants in the genus are tiny, only a few centimeters tall, with small flowers (1.5-2 cm) on short flower spikes. This species is 7 cm tall with long 20 cm flower spikes and 4 cm flowers. The flowers are typical in shape and color for the genus and have the long "tails" for which the genus is named. Their obvious resemblance to Masdevallias had them classified as Masdevallias at one time.
