"This large, caespitose species is similar to Stelis nutans Lindl., but is distinguished by a stouter habit with twice larger flowers. The dorsal sepal is three-veined, and barely five-veined at the base of one collection. The synsepal is rounded and shallowly concave. The lip is triangular and obtuse with a deep glenion descending from a cleft across the bar." Luer & Vasquez 2018
