"This species is distinguished by a dense fascicle of slender ramicauls and narrow, acute leaves, and congested racemes of distichous floral bracts. The sepals are purple, broadly obtuse and three-veined as are the petals. The lip is thick and type A with a large glenion. Stelis amethystina is similar to S. rutrum Luer & R.Vásquez, but differs with usually more than one raceme, smaller flowers, sepals minutely pubescent within, and a thick bar of the lip." Luer 2017
