"This species and the closely related Stelis megaloglossa are unusual members of section Nexipous. Stelis uribeorum is characterized by a narrow, elliptical leaf and a shorter, double-ranked raceme of shiny, dark purple flowers. The rows crowded flowers with a large, rounded dorsal sepal are reminiscent of shelves lined with a collection of human skulls in a museum. The smaller lateral sepals are connate below the middle. The central apparatus is minute, the petals are 3-veined, and the apex of the lip is triangular. Stelis uribeorum is similar to Stelis megaloglossa, but it is distinguished from the latter by the raceme that does not exceed the leaf, and larger flowers with twice larger, spreading lateral sepals that are connate only toward the base."
